In this instructional video, Glenn Dawson of Reset U Fitness dismantles the popular “muscle confusion” myth that originated from marketing campaigns like P90X, which claim that constantly changing exercises each week is essential for muscle growth. Dawson explains that muscle hypertrophy is driven by microscopic muscle‑fiber damage, which can be achieved through progressive overload—adding weight, reps, or altering tempo—rather than by random exercise variation. He emphasizes that most people have poor movement patterns due to lifelong habits of sitting, improper sports technique, and inadequate rehab, leading to bad neurological firing sequences and injury risk. The video argues that practicing correct form repeatedly builds proper neural pathways, whereas constantly switching exercises creates bad habits. Dawson recommends focusing on the basics: mastering form, using structured programming, and occasionally varying tempo, repetitions, or exercise order to keep stimulus fresh while maintaining consistent movement patterns. The video concludes with a call to action to use Reset U’s assessment and coaching services to “reset” one’s body.

Muscle confusion myth. See, about 10, 15 years ago, P90X came out with this awesome thing called muscle confusion. And after that, everyone thought you had to do a different exercise every single week, sometimes midweek, to confuse your muscles so that they can grow. This is an enormous myth, and it actually makes things worse. Stick around, I'm going to show you exactly why and what the best thing is for you to grow muscle and, you know, eliminate injury risk. Hi, I'm Glenn Dawson with Reset U Fitness, and today we're going to talk about the muscle confusion myth. So the muscle confusion myth started by people just trying to get more out of it, and they used an awesome, awesome marketing tool to create this word called muscle confusion, right? But you don't need to do a different exercise for you to have muscle confusion or to tear muscle fiber on a microscopic level. All you need for you to grow muscle is for those microscopic spindle fibers in your muscles to tear, repair, and grow. All that could take is just adding more weight, adding more repetitions, trying a little harder, or even just increasing your tempo. So instead of just repping stuff out like this, you could just go slower with like a 5-5-5 tempo. And you actually tear more muscle fibers this way because you're tearing different types of muscle fibers at different parts of the actual movement. On top of that, most people have crappy movement patterns. I'm going to say this again. Most people have crappy movement patterns. They don't move correctly. We do this free overhead squat test assessment at ResetU and no one's ever done it correctly the first time. Most of us are sitting in chairs since like kindergarten. And then playing sports incorrectly, we get injured. We don't rehab correctly, or we sit at a desk because we have a day job that just puts us in front of a desk and we're hunched over like this the entire time typing on a keyboard. We don't move correctly. We don't have the proper flexibility. What this means is if you're just putting a bunch of different crazy exercises into your body all the time, your body can't learn how to move proper. So if you're thinking in the gym, is my form off or is it correct? You're probably right. It probably is correct. See, you've heard this myth called practice makes you perfect, but it's not true. Practice just creates habits. And if you're constantly doing weird shit like my friend here, then you're creating bad habits for your body. What you want to do is the basics. Get your body to move correctly. Have a specific plan for your body to learn how to move correctly and then get your neurological sensors to just fire the way that they're supposed to, literally all the time, in the right sequence, when they're supposed to, over and over and over again. And then if you're concerned about not growing muscle, change up your tempo, change up your repetitions, change up the order of your exercises, superset it with something else. But it all goes back to the basics. If you can do an exercise correctly with the proper form over and over and over again, then when you go do your sport or you go run or you go jump or play with your kids, even your body does what it's supposed to. Your neurons fire in the right sequence and you don't get injured. It's awesome. Now, if you're doing something different every single time, your body can never, ever, ever learn the correct patterns because you're practicing weird shit all the right time, all the wrong times. And it's just all discombobulated like my friend behind me. So if this video brought you value, make sure you share it. And if you know your neurological sensors are firing the wrong way and you have bad form when you work out, don't move correctly, you need a reset. And that's exactly what we do here at ResetU.
