Why Doing Too Much Keeps Crashing Your PCS Recovery

In this solo instructional video, concussion survivor and PCS coach David Brimacombe explains why many post‑concussion syndrome (PCS) recovery plans fail when they rely on large, rapid lifestyle changes. He argues that the nervous system after a concussion is hyper‑vigilant and responds to consistency, not extremes. The primary early‑stage goal is not immediate symptom reduction but creating cellular safety by establishing tiny, repeatable habits—such as two minutes of walking, a single gratitude note, or swapping one food item. Brimacombe introduces the concept of a personal symptom threshold: any activity performed above this limit triggers symptom spikes, leading to crashes and loss of routine. By staying below the threshold and incrementally increasing effort week‑by‑week, the brain learns that the new behaviors are safe, gradually expanding tolerance. He uses a fire‑starting analogy—kindling (small steps) versus gasoline (big jumps)—to illustrate why a slow, systematic buildup yields a controlled, sustainable recovery, whereas an “inferno” of over‑exertion overwhelms the nervous system. Throughout, he shares his own experience of multiple concussions, the pitfalls of trying to return to pre‑injury performance too quickly, and the resulting burnout cycles. The video concludes with an invitation to join his PCS Resilience Collective, a structured program that guides participants through ordered, personalized lifestyle modifications.

If your recovery habits keep collapsing after a few days, this video might explain why. Now understand that when you're in that deep recovery phase, you watch videos, you read stories, you talk to people who have recovered, who are recovering, and you get inspired. So what you do is you install a huge dietary change New supplements, exercise every day. Then life happens, your symptoms spike, and everything crashes. See, your nervous system doesn't respond to extremes, it responds to consistency. Hi and welcome to the PCS Resilience Collective. My name is David Brimacombe, and after 7 concussions over 20 years I learned that before a habit can improve, it has to exist consistently. Let's begin. Now, one of the things that is most commonly misunderstood in the PCS recovery phase is that your main goal with that initial part of your recovery, when you're starting from going and doing nothing to doing something, isn't necessarily to reduce your symptoms. isn't necessarily to feel better in the moment. The goal is to create safety in the cell. Now understand, the brain's main goal is to keep you safe. If you start doing things that it is not accustomed to, it doesn't align with your current identity, the alarm systems are going to go off, okay? Those symptoms are going to spike, the anxiety is going to rise, not because what you're doing is wrong, but because what you're doing is going against that current identity, that current existence that you're living. So if you go from doing nothing, add in a bunch of different routines, your body's not going to respond well because what you're doing is going against what it had been doing prior. Your main goal in that initial part of your recovery isn't to excel, isn't to feel symptom-free. It's to install small foundational habits that you can stack later on. It's 2 minutes of walking, 1 point of gratitude, changing 1 food item in your diet. It's not everything. It's 1 thing. And what that does is it convinces the self, it convinces your nervous system, this is the person I am becoming. I am no longer that person who sits and watches my own recovery. I am now active. I am the person who is going to change the state of my reality, and it's going to take one step at a time. Okay, for me, this was the hardest part to grasp. I wanted to be better. As soon as I installed a few new routines, new systems in my PCS recovery, I started to feel a little bit better. But the problem with that Is that I wanted to feel perfect. I wanted to feel like I did prior to my first concussion. So I added more and more and more, and I got to the point where I completely exhausted the systems. I exhausted myself. I burnt out, and I started back at square one. I was defeated. What is happening? How can I not add all these things that I've heard so many times are going to do you good? Adding, you know, 20 minutes of meditation, exercise every day, changing my entire diet. Now, on the whole, on the surface, that seems like an amazing idea. The problem lies in the fact that your body's been deconditioned for so long. For many of you, it could be weeks, months, years. For me, it was multiple years of being deconditioned. My systems and my state weren't ready for that level. of change. I needed to start really small and slowly scale up in order to improve. Now again, if this is something that's only been weeks or months in the making, you can probably scale a lot quicker. For me, it was years, and it took a long time to get to the point that I knew I could get to. So here's the key, okay? Stop wanting more. Stop wanting to be that peak self. What you always want to do is be one step better. Always improve. Always try to be better this week than you were the week prior. Focus on small segmental sequential gains. I know that if I put in the work, I know that if I do 2 minutes of exercise this week, which might seem like nothing, I can do 4 the week after. Maybe 6 or 8 the following week. But it takes time. It takes consistency. I am not only changing my own exercise tolerance in this case, I'm changing my own state. I'm convincing my nervous system and my brain, this is okay. I am capable. I am able. This is not going to cause me harm. The alarm signals don't need to come off. Okay. Because what I'm doing is I'm improving myself. One step at a time. Now, how do we do this safely? Everyone has what's called a threshold. So for anything that you're going to do, you're going to have an upper limit where if you go beyond it, you're going to spike those symptoms. For example, if I walk 10 minutes and I don't feel symptomatic, but 12 minutes causes all those symptoms to stir, they escalate to the point where I don't feel like walking anymore. That is my symptom threshold. That is the point where I know I cannot exceed in this given moment. Will I be able to walk more next week? Possibly. Okay, but in this moment, I need to exercise below, because if I exercise above, not only are those symptoms going to spike, but it's also going to make my recovery harder. Because tomorrow I'm not going to want to walk, and maybe I'm not going to want to walk for a couple days, and then I get out of routine. When I get out of routine, I no longer want to do the things that are actually helping and healing me. See, if you go too hard and you push yourself past your limits, you're constantly going to be playing this game of, oh, I've crashed, I'm going to wait for a few days, I'm going to get back in it, then I'm going to wait for a few days. And you do not have consistency. Your body doesn't know what to expect, and therefore every time you exercise, it's going to become symptomatic because That is what it's accustomed to. It's now made that association between when I exercise, my symptoms spike. It doesn't have to though, because exercise is not your problem. Okay? Your tolerance is your limit, and working below it is your solution. Again, you want to have your brain saying at the end of the day, "I can do this tomorrow." I feel comfortable that I can do whatever the activity. Whatever the recovery system or technique, I can do it every day. Maybe I want to sit in a meditative state for 5 minutes. That 6th minute, that 7th minute really starts to push my system. Okay, I'm going to do it for 5 minutes because I know that tomorrow I'm going to want to do it for 5 minutes again. If I do it for 6, I'm not going to be motivated to go back the next day because I've now made that association. Of this activity causes my symptoms to spike. See, it doesn't take a lot. What you're doing is you're changing your internal state. You're not necessarily worried so much about how much is this going to help me recover the systems that have been dysregulated, okay? But though that will happen as a byproduct, your focus is on safety in the system and convincing yourself that this is going to be the route you need to go. Think of the analogy of starting a fire. Now, there's 2 ways to go about this. You can go the slow, systematic way. You can start with some kindling, add a few logs, light it, and it will eventually turn into a nice fire. Okay? Or you can take some kerosene, gasoline, dump it on, and you'll see an inferno. Now, the inferno becomes out of control. Okay? That is what recovery happens when you try to add too much too soon. Okay, your recovery becomes an inferno. It encompasses your whole life. It becomes out of control. Your body doesn't like that. What your body wants is a slow, systematic buildup. Okay, you're adding a log every time you introduce a new technique. Okay, that new technique is going to allow that fire to get bigger, brighter, but still be in control. You need to maintain control of your systems because once you become out of control, Your body shuts down. That nervous system just can't take it anymore. Remember, after a concussion, that nervous system is hypervigilant. It is picking up cues in the environment. Any and everything are causing those symptoms to flare, you to feel those anxiety and those emotions. So keep it simple, okay? Start small and scale later. This is something that I wish I learned at the early part of my recovery. It took me Years to figure them out. What I'm telling you today, my point of this channel is to be your guide, is to be your mentor, is to help you walk down the path that I wish I had. Okay, the path that I walked forced me to go in a circle multiple times until I finally figured it out. Okay, I have a waitlist down below for my PCS Resilience Collective. Okay, that waitlist is to get on a program where I want to help you. succeed. I want you to find those lifestyle modifications, those things in your life that you can change, because you have the power to be a change agent in your recovery. Okay, you just need to know what to do, when to do it, what the order is, and I can help you with that. Thank you very much for listening to the end. I hope you have yourself a great day.
