The ULTIMATE Travel Workout Routine, Microdosing GLP-1, Increasing Libido *Without* Testosterone Replacement Therapy & More! Solosode #481

In this episode of the Ben Greenfield Life podcast, the ultimate travel workout routine, microdosing with GLP-1, increasing libido without testosterone replacement therapy, and a whole lot more. Fitness, nutrition, biohacking, longevity, life optimization, spirituality, and a whole lot more. Welcome to the Ben Greenfield Life show. Are you ready to hack your life? So, let's do this. Welcome, welcome to today's show, which is apparently brought to you— I know you guys are always asking me what I'm drinking during the show, and it widely varies. I have zero plan, zero strategy whatsoever. I just go out to the mini fridge in my garage and grab— whatever the spirit is hankering me to grab. Today, it's Ophora. Ophora? Ophora. Should be Ophora. Ophora, nice glass of water. It says water for wellness, nano-pure restructured hyper-oxygenated. I am going to do a podcast though with this company. I'm very curious about how they make nano-pure restructured hyper-oxygenated water. So, regarding skepticism, I suppose, I have been doing reaction videos. I want to let you know If you go to my YouTube channel, yes, this is a shameless plug, I recently did one on the myth of lean protein and why lean protein is not really in my vernacular. I also did one on the trendy new 12-3-30 treadmill workout, walking for 30 minutes at a 3.0 speed, 12% incline. I also did a video on what happens when big food companies buy health food companies like how Pepsi just bought Siete for like $1.3 big-a-billion dollars. So anyways, all those are on YouTube. I'll link to them too in the shownotes, which are going to be at BenGreenfieldLife.com/481 today. And today, man, I've got— well, I guess I have one news flash for you, but the rest of everything else is all Q&As. It's all Q&As. You guys wrote in with some fantastic questions, and heck, I think I'm just going to start off by replying to your questions and answers. My answers, your questions. Leslie wrote in. Oh, and by the way, if you want to write in, just go to BenGreenfieldLife.com. Not only is a handy place to leave a question for the podcast, but my AI clone is on there. So, you probably don't even have to leave a question for the podcast, you can just ask my clone. It's in the lower right-hand corner. It's been trained on about 10 years of my podcast, books, writings, et cetera. So, you can ask my clone. Don't even worry about asking me. Heck, how do you know I'm not a clone right now recording this podcast? It could be. We're living in that era now. So, microdosing GLP-1. Leslie asked, "What do I think about microdosing with GLP-1?" Well, I'll tell you an interesting story. I interviewed someone about these Ozempic and GLP-1 agonists and tirzepatide and magapetide and aleponapeptide and all the peptides out there. Her name is Dr. Tina Moore. It was a fascinating interview. And, being the good little immersive journalist that I am, I actually injected with Ozempic for 2 weeks leading into the show. In increasingly higher dosages to just see what the dose response to the stuff was. Starting off, it controlled appetite shockingly well, meaning like I would make myself my beautiful glorious morning blueberry coconut water smoothie and then just kind of sit there staring at it asking why the heck I made myself a smoothie because I didn't really want a smoothie or anything at all for that matter in the first place. I made myself a beautiful sous vide for 3 hours then smoked rubbed in rosemary and thyme, beautiful bison porterhouse steak and sat there, took one bite, dipped it in a little Primal Kitchen ketchup and had one bite and then pushed myself away. I actually lost 3 pounds of muscle during that experiment. And, as I increased the dosages, began to experience what I suppose would be some of the more concerning side effects with higher dosages. I got nauseous. I had gut issues, couldn't stay off the toilet. So, works amazingly well, but at the dosages that most doctors are now prescribing, it does result in some pretty significant gastrointestinal issues— nausea, diarrhea. I felt a few times like I was going to vomit. I had a horrible gastric reflux and constipation. And that's what a lot of users who are taking standard dosages of something like Ozempic will report. Some users have even reported experiencing pancreatitis, and that, that's a life threat. Potentially inflammation of the pancreas involving severe abdominal pain and nausea and vomiting. And so, there are other side effects of GLP-1 agonists that have been observed primarily in animal studies, but things like thyroid tumors, cancer. And I'm not saying this to just scare people away from using GLP-1 agonists because like I said, I get very small dosages. In my experience, I was like, holy cow, if I did have appetite control issues or if I did want to lose some weight, which I didn't, I was just doing to see what it felt like. This would be like a total secret weapon. So microdosing, though, is, I think, a fascinating concept when it comes to something like Ozempic. Microdosing, as you're no doubt aware, refers to taking less than the standard dose of anything like a medication or psychedelic or anything like that to achieve some of the benefits while minimizing the side effects. You get people microdose with, and I've done this, microdose with psilocybin. You take a mega dose of psilocybin, let's say you take 2 or 3 or 4 or more grams and you might be talking to fairies and running through a pastoral field in your underwear. And, you take a smaller dose like let's say 0.25 to 0.5 grams and stuff just comes alive a little bit, better sensory perception, music becomes more colorful, images pop out a little bit better in nature. Some people even used it as so-called hunting medicine in some tribes. And I think there's a time and a place for something like that, right? Like a sub-perceptual dosage. So when we look at microdosing with a pharmaceutical drug like a GLP-1 agonist, this would involve taking a smaller than prescribed dose of that medication to achieve some of the benefits while potentially minimizing some of the concerning side effects. So you could get some of the appetite and food craving suppressing benefits of GLP-1s without experiencing the range of side effects that one would commonly experience when one is using the standard dose, which is the dose that has traditionally been used in diabetic management. And indeed, when I interviewed Dr. Tina Moore, and I— that interview might have come out by the time this podcast is released, and if so, I'll link to it in the show notes, uh, she described how most doctors in her opinion are massively over prescribing or not overprescribing, but overdosing in terms of the volume dosage of something like Ozempic. And when you consider the fact that Ozempic comes in prefilled injection pens with specific dosing increments, you could technically just stick with the smallest dose and not increment your way up. Or, and many people are doing this, they're talking to their physician about working with a compounding pharmacy in order to get a microdose of something like semaglutide, aka Ozempic. So, with the microdose, I'm already being asked by some people who I shared about my experiment with how much I was actually using when I microdosed. So, for semaglutide, the actual microdose is 0.5 to 0.125 mg. Okay. So, this is a very, very small amount, meaning that for 50— well, let's use a little bit friendlier language here, micrograms. Okay. So, I was taking 50 micrograms and that was the microdosing amount I used that worked fantastically with no side effects. 50 micrograms meant that with a full insulin syringe, I was pulling my peptide, my semaglutide because I was using the peptide version, back to the 3-tick mark, right? So, 3/100 of what appears on the insulin syringe, almost a barely perceptible amount if you were looking at it visually. And that's all that it took. I mean, that, that's how potent this stuff is. So in my case, I think it was a 5-milligram bottle that arrived, and I reconstituted it with 3 mL of the sterile water. And so that meant that based on the rough math— and there are peptide calculators all over the place on the internet, by the way— pull it back to the 3-tick mark, and that was all that it took. And the levels that you would take for a microdose are going to vary from GLP-1 to GLP-1. Like, there's another one called tirzepatide. For tirzepatide, it'd be an extra decimal point. It's actually 500 micrograms. And in a case like that, same dosage mixing ratios, you'd pull the syringe back to the 30-tick mark instead of the 3-tick mark. I'm not a doctor, I don't want any of this to be misconstrued as medical advice, but that was what I did and those were the effects that I noted. So, Dr. Tina Moore, she's actually pretty fascinating. I would visit her website. She even has a whole article about microdosing with GLP-1s, T-Y-N-A. And, listen to my podcast interview with her. It was fascinating. And, of course, after finishing that episode, I quit using GLP-1s again because I don't I need to lose weight like I need another hole in the head. It's hard for me to keep weight on. I got to eat 4,000 calories a day to maintain weight. I have a screaming high metabolism. I got a bunch of leftover muscle from my bodybuilding days. I walk all over the place and barely drive my car at all. I'm not a candidate for GLP-1. However, she even got in our podcast into the idea that there are a multitude of beneficial side effects that go beyond just weight loss, things like lipid management. I believe she discussed blood pressure management, there's blood sugar management, et cetera. One of the very interesting things that I noted, by the way, anecdotally, was that I had very low blood sugar. No surprises here because I wasn't eating that much, but I didn't have a lot of the symptoms of low blood sugar, which I thought was interesting. Like, normally if my blood sugar— and I wear a continuous blood glucose monitor to track this— were at like 50 to 60, I wouldn't be able to sleep. I would just wake up hungry. But when I was using the microdose, and obviously as I went along, larger doses of Ozempic, I was sleeping all night long just fine with blood sugar between about 50 and 60. And I'm not arguing that hypoglycemia to that extent is a good thing, but I did think it was interesting that, that what would normally cause me a lot of issues from an energetic standpoint wasn't really causing any issues. So anyways, there you have it. And there are my brief thoughts on microdosing with GLP-1. Leslie, great question. Jeremy says, Ben, I have followed you for at least the last 10 years. My apologies to you and your family, Jeremy. Hopefully, you haven't gotten bored of me in the past decade. I think it's wonderful what you provide for free to help people out. Well, thank you, Jeremy, but it's actually not free. Anytime you hear an advertisement on this podcast, I get paid. That's how podcasters make their money. So, I wish I could say that I'm doing this all out of the goodness of my heart, but I do make a few bucks when I record an episode because people advertise on it, just being transparent with you. Anyway, so he says, Jeremy says, "My question is, what could cause and how could it be fixed a low libido in an otherwise highly athletic and healthy 43-year-old man. He says he's 6'3", weighs 208 pounds, has a body fat 10.4%. So, many, many things can cause low libido. And, I would rather than spending time talking about something I've talked about quite a bit on the show before, a thorough addressing of low libido, I'd actually like to come at this from the testosterone standpoint because Jeremy's question is similar to what I'm asked about a lot by guys. Like, my libido is low, Should I get on testosterone, bro? And the answer is not necessarily. So the first thing we should consider here is that Jeremy says his body fat percentage is 10.4. Depending on genetics, that might be a body fat percentage that is just too low all around for adequate testosterone, adequate amounts of other hormones or neurotransmitters, things like oxytocin, serotonin, dopamine, things that would increase pleasure and libido. The latest big analysis on healthy body fat percentages for males put them at around the 11 to 22% range. Females were anywhere from 20 to 33% as far as like a healthy body fat percentage. So it could be that Jeremy just needs to put on a few pounds. But there are some other things to consider here, particularly when it comes to libido. Because libido is influenced by more than just testosterone levels, right? There's a lot. There's psychological state, right? Stress, anxiety, depression. All of that can, of course, influence libido, relationship dynamics, your neurotransmitter balance, which I briefly just mentioned. Dopamine, serotonin, those play significant roles. So just boosting your testosterone levels, that's really not contrary to popular belief. Going to necessarily address the root cause of reduced libido. When somebody tells me they have low libido, I look at this a little bit more from a standpoint of how much stress are you under, work stress or relationship stress or other lifestyle stress. Do you have anxiety issues? Are you struggling with depression? What does your neurotransmitter balance look like? How does your amino acid look? How does your amino acid intake look? How does your fatty acid intake look? Have you gotten a blood test to see if there are any imbalances in any of these variables? Sometimes there's a negative feedback loop where guys struggle with erectile function. And if there's dysfunction, that further dysregulates libido because they've got a little bit of a blockage when it comes to the sexual performance dynamics of libido. And, you know, you would come at that from the standpoint of cardiovascular health, blood flow, nitric oxide, making sure that you're, you're caring for your underparts, you know, not wearing excessively tight underwear, not spending too much time in hot tubs, you know, even doing things like cold plunges, you know, all of, all those things can help when it comes to erectile dysfunction. A lot of the same things you do for cardiovascular health you do for erectile function. But here's the thing with testosterone. Once your testosterone levels reach a certain threshold, more testosterone doesn't necessarily translate to higher libido or higher sexual performance. As a matter of fact, research has shown that men with normal baseline testosterone levels that fall within reference ranges often experience no significant increase in libido if they were to go to supraphysiological testosterone levels by using TRT or some type of herbal remedy to increase testosterone. So, the other interesting thing is that testosterone, if it is overdosed or improperly dosed, can even be converted to excess levels of estradiol, which is a form of estrogen. And improper management of that can lead to reduced libido. So, you know, kind of paradoxical, but if you're on testosterone replacement therapy, sometimes if it's getting over-aromatized into estrogen, it can reduce your libido. So yes, testosterone is great for workout performance, for recovery. One of the most common things men report when they start on testosterone replacement therapy is that they can work out day after day after day and just keep coming back for more. Because they're recovering that much faster. And that's honestly something you got to be careful with. Sometimes you get on TRT and you can get injured because you're training and able to train and motivated to train so much more. But I would say that before looking into something like testosterone therapy, even though it is something you should test if you have low libido, there are other things that can effectively enhance libido when we look at biohacks or supplements or peptides or lifestyle factors. So, I'm going to share a few of my more potent tips with you for increasing libido, Jeremy. And while you can, of course, apologize to your significant other for having to deal with 10 years of this podcast, hopefully you won't have to apologize to them for this bit of advice. So, the first is there's a peptide. I realize that peptides go in and out of legality nowadays. This is one you can still find. There are peptide websites like Peptide Sciences or Limitless Life Peptides. There physicians who work with compounding pharmacies to prescribe peptides. But the specific peptide that you may want to look into, it's called PT-141. That is a peptide that works by stimulating what are called melanocortin receptors in your brain. They target the hypothalamus that plays a role in sexual arousal. So unlike medications like, say, Viagra, that would act on your vascular system to increase nitric oxide or decrease the rate at which nitric oxide would be broken up and down. PT-141 affects your central nervous system, increasing sexual desire in both males and females, by the way, without necessarily influencing testosterone levels. And clinical trials in both men and women have shown that PT-141, the peptide PT-141, significantly enhances libido and sexual satisfaction. As a matter of fact, there's one very interesting study in women with what's called hypoactive sexual desire disorder, I think that name kind of speaks for itself. HSDD, hypoactive, underactive sexual desire. It improved arousal, desire, and orgasmic quality in those women. And in men, it's been found to not only increase libido but also improve erectile function. So again, that one is called PT-141, also goes by the name bremelanotide. So that is a pretty potent and powerful one that you can look into, PT-141. Another one would be L-citrulline. There's one powder packet, it's called Joy Mode, and it contains an amino acid that boosts nitric oxide production. You'll also find L-citrulline in a lot of pre-workout formulas. It improves blood flow to your entire body, including, like Viagra does, to genital tissues without necessarily requiring you to have a prescription for a little blue pill or going to a fringe online pharmacy to find a generic form of Viagra. So, L-citrulline has been shown to enhance sexual performance and can indirectly increase libido by improving sexual satisfaction, kind of like that positive feedback loop. You're having great sex, so your libido goes up. A lot of us have experienced that. One study in men with mild erectile dysfunction found that L-citrulline supplementation significantly improved erection hardness but also frequency of intercourse. And, that is probably because men who were taking it enjoyed sex more. And again, that can create this positive feedback loop of higher libido. Maca root. Maca root is another one. Maca root is something that can enhance both libido and fertility. It also supports adrenal function. It's a very potent adaptogenic herb. A lot of people don't like the taste of it. There are many coffee mixes, et cetera, that are using maca as like a coffee mix or tea mix alternative. But studies on humans have shown that maca can enhance sexual desire in both men and women. There is one placebo-controlled study that showed that maca improved libido in men with erectile dysfunction. And, uh, they also did another study on men who had antidepressant-induced sexual dysfunction. That's probably something I should have mentioned when I was discussing reasons people have low libido. But if you're on an SSRI, uh, because that does, uh, as the name implies, inhibit the reuptake of serotonin, it can decrease libido. And maca seems to help if you're on an SSRI and have SSRI-induced low libido. So that's interesting. Again, don't take that as medical advice. I'm not a doctor. I know I keep saying that, but maca root would be another. Fenugreek. Fenugreek has also been shown to be something that can improve libido, in some cases very similar to L-citrulline, because it can assist with erectile quality as well. But they had one study in healthy men that showed that fenugreek supplementation significantly improves libido and overall sexual satisfaction compared to a placebo. And there is a small amount of research indicating that it may do similarly in women. Yohimbe. Yohimbe is an extract from the bark of the yohimbe tree, and it works by increasing norepinephrine levels, and that in turn can improve blood flow and sexual arousal. It acts as what's called an alpha-2 adrenergic antagonist. All that means is that it affects the central and the peripheral nervous system in such a way that improves sexual function. And indeed, multiple studies have shown that yohimbine can improve sexual desire and performance, particularly in men with erectile dysfunction. The only downside to yohimbine compared to something like fenugreek or maca or L-citrulline or PT-141 is that it because it's a central nervous system stimulant, it can keep you awake. So, if you're taking this on date night, just be aware that you might be up at 2:00 a.m. staring at the ceiling thinking about your partner who's in bed next to you trying to get some sleep. PT-141 can also do that but via a different mechanism. It can cause erections that can be somewhat painful and distracting and last 4 to 6 hours. So, that also could, of course, impact whatever your wearable is telling you was your sleep quality the next morning. So, anyways though, we don't just have to use supplements or herbs to increase libido. There are some other things that are associated with an increase in libido. Cold therapy. I mentioned that as something fantastic for testosterone levels, but it also increases norepinephrine levels that helps to increase energy, improves mood. And, for many people, there are no studies on this, but reportedly, Anecdotally, it can lead to a higher libido. My recommendation would not be to take a cold bath or a cold shower immediately prior to sex because you get the infamous Seinfeld shrinkage effect. However, having a regularly scheduled cold practice such as in the morning help to stabilize norepinephrine levels so that long-term, you would induce better libido overall. Exercise boosts endorphins and improves overall well-being. And it's pretty common that people who start exercising, particularly weight training, experience an increase in libido. And studies have backed this up, showing that moderate-intensity exercise can improve sexual satisfaction and arousal. So the last thing is that there, there's a small number of studies showing that some type of meditation, mindfulness practice particularly visualization practices focused on increased libido. Visualization works for many things, right? You visualize better sleep, you can visualize better relationships, you can visualize increased libido. They may also help with something like this, a meditation or mindfulness practice based on increasing libido. I realize that sounds boring and very unsexy. I've never tried meditating or mindfulness practices myself for improving libido or anything related to sexual performance. But some people say, and some studies back it up, that that might actually be another tactic. Uh, so, uh, coming full circle, we've got peptides like PT-141, we have supplements like L-citrulline, maca, fenugreek, and yohimbine, we have cold plunges and exercise, all as ways that we could naturally increase libido without necessarily using testosterone replacement therapy, which may not actually increase libido at all. So, good to know and great question from Jeremy. Alright, we are going to move on to Kyle. Kyle's got an interesting question. He says, "What does your current travel workout routine look like?" Well, if you're unfamiliar with what I do as a job, I record this podcast, I write books occasionally, I have a new one coming out in January. Shout-out to my book, Boundless, the new and updated version of Boundless. I invest in some companies and do some advisory work for companies. I coach and consult with people throughout the week. People hire me for phone calls to talk about health issues or workout performance, nutrition, diet, their labs, et cetera. Right now, I coach 8 people. So, every month, people pay me to coach them and kind of oversee their exercise and their nutrition program. And, I also travel to speak. I travel around the world to speak, and sometimes I'm traveling 2 weeks out of every month. So, I'm on planes a lot, I'm traveling a lot, and of course, I have to stay fit when I travel. So, what does that look like? How do I stay fit when I travel? So, first of all, I want to describe to you what my travel workout kit looks like. I just packed last night for a trip I'm leaving for tomorrow to Phoenix. So, my travel pack, my lightweight travel pack, Step 1 is I pack BFR bands or katsu bands. Both are somewhat similar. They allow you to restrict blood flow to the arms and the legs. And even in the absence of weights, proper gym, et cetera, fool your muscles into thinking they're lifting a heavy weight when in fact all you may be doing with them, like I do, are bodyweight exercises, elastic band exercises, walking, swimming, et cetera. I have to admit that I'm a little bit lazy. And even though I have the fancy $1,000+ Katsu bands, which are the Japanese version that have a digital little device that allows you to, using your phone app or a digital controller, very precisely adjust the millimeters of mercury of the Katsu bands. Sometimes I'm pretty old school and I just got the $50 set off Amazon and just strap those bad boys on. I go back and forth. I kind of like the simplicity of just throwing the cheapo ones on. Call me a Luddite, but the Katsu ones are kind of like the crème de la crème if you really are into digital self-quantification and having everything very precisely controlled. But whether it's the BFR bands or the Katsu bands, that's about maximum of like a pound worth of equipment that fits into a very small space. I don't ever check any bags when I travel unless it's a big long trip like multiple weeks internationally. So, I'm only carry-on. Okay, just so you know. So, BFR bands or katsu bands, one elastic band, just a mid-resistance elastic band. The one that I choose is one that if I were to do an overhead press with an elastic band, I couldn't do more than 10 reps. Okay. So, that's about the level of resistance I'm going for, which for me is a mid-size elastic band. And then, I have a doorframe suspension strap that's like a TRX trainer. Mine is the $25 version of the TRX trainer that I got off Amazon. I can throw in any hotel room door, well-constructed Airbnb door, et cetera, and be able to do things like pull-ups or knee-ups using a doorframe suspension strap. In the absence of something like a pull-up bar, it comes in quite handy. So, I'm not limited to just doing, say, push-ups and squats. So, that's it. That's my exercise kit is the BFR bands, the elastic band, and the doorframe suspension strap. Using that kit, I can very easily work out in any hotel room, backyard, basement, et cetera. And I'll describe what my workouts are to you momentarily, how that actually manifests itself when I travel. I also have a couple of other things. I have a water bottle called a Mobot water bottle. And again, I travel very light, so I'm always thinking, how can I squeeze as much as possible into as small a space as possible? Mobot is a bottle that can double as a foam roller or as a deep tissue device. Brilliant idea. Stainless steel bottle. I can drink from it at airports, so I'm not spending $7.99 on a bottle of water at the airport, which I realize is ironic as I sit here and sip what is probably a $40 bottle of hyperoxygenated water. But those MOBOT bottles are super cool because I can do all my deep tissue work with that. And then, in addition to that, I have one of those really small massage guns. The Power Plate is the brand that I use. TSA doesn't care about it. They seem to kind of raise an eyebrow at the bigger ones that they consider to be power tools, which apparently are banned by TSA for travel. And I have had those confiscated before. The Power Plate, a little vibration gun, never had any problems with that. So I got that in there. And then the only other thing is in my fanny pack, I have this little device called a Relaxator, and it allows me to go for walks and restrict airflow when I walk if I want to do some breathwork while I'm walking. And that's it. And then, all of that is literally total everything including the percussion gun, the water bottle, everything easily under 4 pounds. Okay. So, all of that goes into my backpack or my carry-on suitcase. I have a small expandable carry-on suitcase and a backpack. That's all I travel with. Using all that, what do my workouts actually look like? So, ideal travel routine for me, let's say I am traveling for 6 days, Day 1 would be 30 minutes of BFR training in my hotel room. Gold standard workout for me is I put the BFR bands on both my arms and my legs, and I do 30 squats, 20 push-ups, 10 doorframe pull-ups, and then I do 30 lunges per leg, 20 dips on the coffee table or the chair in the hotel room, and 10 Little Bigs, which you can Google, but that's just like a core exercise. And I do an AMRAP of that. So 30 squats, 20 push-ups, 10 pull-ups, 30 lunges, 20 dips, and then 10 of the little bigs. Usually as a finisher, I'll take out that elastic band and just do as many overhead presses as I can. Although a lot of times I'm just using the elastic band like in the airport to throw in some extra overhead presses or whatever. But that's what it looks like. So an AMRAP of 30 minutes. And if I have time after I finish that AMRAP, I leave the elastic bands on and I go for a walk, or I leave the BFR bands on and I go for a walk while I check my emails and catch up on a little bit of work because I shared this research, I think, 2 episodes ago. Even walking with BFR bands helps to maintain muscle because of the blood flow restriction. And then, so that's day 1. Day 2, I would typically not use the BFR bands or anything else. And day 2, I'll usually just like go for a long walk, stop for burpees along the way, do a few occasional sprints. If there happens to be an exercise machine where I'm staying, I'll do a little bit of cardio. And so I alternate back and forth between day 1, BFR bands and walking, day 2, walking with some cardio and calisthenics thrown in, and that's it. So let's say that I know that I'm traveling to a place where there's going to be a good gym and I really don't have to do all that stuff in my hotel room. Well, in that case, I have a little bit of a different approach. If I have access to the average hotel gym or my Airbnb is at some kind of a condominium complex that has a decent gym, my workouts are all full body. The reason for this is when you travel, it's inevitable that you're going to miss some workout days. And, if you're doing a body part split, let's say you're doing a, I don't know, push-pull leg split or you're doing a chest, shoulders day 1, back, arms day 2, core, legs day 3 type of split. Well, when you travel, it's just hard to not miss days occasionally. Like, it might be an airplane day, or the day might have a schedule that's a little bit different for you. And if you miss a body part split day, you miss a day, right? So that means that if you're not doing a full body workout and you miss a day or two, you're missing out on certain body parts just because they're not getting work. If you're doing a push-pull legs routine and you miss legs, well, you miss legs, right? And so, then you're going to be the guy who's pushing and pulling with toothpick legs or the girl who's pushing and pulling with toothpick legs. So, I always do full body. My full body workout because I'm all about reducing decision-making fatigue and knowing exactly what I'm going to do right when I walk into the gym is very simple. I do a 2-minute cardio warmup and then I choose one exercise that's a horizontal push, one exercise that's a horizontal pull, one exercise that's a vertical push, one exercise that's a vertical pull, and then something for the core and the legs. Okay. So, what this would look like would be I walk into the gym, I do 2 minutes on the bike, and then I do the chest press, for my horizontal push, the row for my horizontal pull, the leg press for my legs, the overhead press for my vertical push, the pull-down for my vertical pull, something core like a low back extension or whatever for my core, and then go back to the 2 minutes of cardio. And I'll do that as an AMRAP. So I walk into the gym, look at my clock, okay, I got 45 minutes. That's all I'm doing. 2 minutes of cardio, horizontal push, horizontal pull. Legs, vertical push, vertical pull, core, back to cardio. It's very simple. It keeps me from missing body parts due to body part split style workout. And again, like, I've got the option if I've got my BFR bands and my elastic band and my doorframe suspension strap to not even walk out of my hotel room to even go hunt down the gym. But if there's a good gym, that's usually the approach that I use. And that is basically how I work out when I travel. Last thing I should mention is that if I'm doing the workout I just described you, the 2 minutes of cardio with the horizontal push, horizontal pull, legs, vertical push, vertical pull, core, then the following day, it's very similar to the day that follows the day I do the BFR training. I go for a walk, I do a little bit of calisthenics, I move my body, do a little bit of cardio or burpees. So, it's always alternating one day of some kind of strength training, one day of some kind of cardio walking and core. When I'm traveling. And that's it. And I stay pretty fit when I travel and I enjoy that routine. I could do it my whole life. It just works. So, great question, Kyle, and hopefully that helps to kind of decode my approach to training when I travel. So, I really wanted to, and I'm glad I have time to do this, I wanted to also bring to light a recent study that I thought was fantastic because it honestly speaks to something that I do quite often. I use essential amino acids as a tool to maintain or build muscle. And I'm often asked, well, why would you need to use these if you are doing something like a whey protein or a vegan protein shake which already has essential amino acids, or using steak or chicken or fish or whatever? So this most recent study that came out in mid-October 2024 is titled Consuming Whey Protein with Added Essential Amino Acids, Not Carbohydrate, Maintains Post-Exercise Anabolism While Underfed. I won't repeat that title in case it made smoke come out your ears, but if you think about it, it's pretty straightforward. When you have something like a whey protein shake and you add essential amino acids to it, not branched-chain amino acids but essential amino acids, EAAs, compared to adding carbohydrates to that whey protein, you get better anabolism or muscle building effects even if you are undereating, even if you are not consuming adequate calories compared to how many calories you're actually burning. Now, in this case, they had subjects consume a whey protein style shake with essential amino acids added to it, or a whey protein shake with carbohydrates added to it, and then they measured muscle protein synthesis, whole body protein synthesis, whole body protein breakdown, and net protein balance. Supplementing with the essential amino acid enriched whey protein resulted in much better post-exercise muscle protein synthesis even during an energy deficit compared to adding the carbs into the whey protein. Now, in this case, they were using pretty high doses of essential amino acids in this whey protein shake. They were using— make sure I get this right, got the study pulled up in front of me now. Okay, it was a 300-calorie shake and they had 48 grams of essential amino acids in there. That's a lot. Like, one scoop of the Kion Aminos, the one that I use, is 5 grams. So that would have been like you do the math, like 9 scoops of essential amino acids. That's a lot. But there have been other studies that came out prior to this that looked into just the same thing using far less essential amino acids. For example, back in 2020, there was a study in which they found that the anabolic response to essential amino acids plus whey protein was greater than whey protein alone And in that case, they were using 3 grams of essential amino acids added to whey protein, which is like less than a full scoop of something like the Kion Aminos. So even a small dose of essential amino acids has an impact at improving muscle protein synthesis compared to not adding amino acids at all to a protein shake. And then there was another study that was in the Journal of the International Society of Sports Nutrition. In 2021 that found that when you add essential amino acids to whey protein, you get better post-exercise whole body protein balance, again during an energy deficit, compared to a regular meal, what's called a mixed macronutrient meal, like your average, I don't know, breakfast with hash browns and eggs and toast, uh, or a whey protein shake. And in this case, again, they did this on a bunch of healthy young men, the amount of amino acids that they used in this case was, was around, looks like 24 grams. Right. So decent amount. You know, in this case, again, if we were talking about the Kion Aminos, that would be 4 to 5 scoops. And again, they saw pretty impressive benefits compared to just using the whey protein alone. So what's the takeaway study here? If you're making a protein shake, it's like, and you're trying to build or maintain muscle, it's kind of a no-brainer, better living through science thing to add anywhere from 5 up to 45-ish grams of essential amino acids to the whey protein shake if you want to see much better muscle protein synthesis. And if you want to know more about just the whole science of essential amino acids and how these work, Angelo Keeley, who is the CEO of Kion, he was recently interviewed on the Mind Pump podcast and they talked for like an hour and a half about a ton of really interesting data on why essential amino acids are like a Swiss Army knife, like a secret weapon when it comes to fitness. That would be a good one to listen to. The Mind Pump guys are friends of mine. They're great dudes, very entertaining podcast hosts, way more entertaining than me.
