76. Why Your Body Adapts (And Why Most People Never Realize It)

Gravity is undefeated and it is asking your body a question all day long: can you handle me? That single idea reshapes how we think about human performance, functional fitness, and why training actually works. When stairs start feeling harder or getting off the floor feels awkward, the movement did not change. Your body’s ability to solve the movement problem changed.

We break down the hidden mechanics behind everyday motion, from balance and force absorption to the ground reaction force that literally pushes back every time your foot hits the floor. Movement is not just muscles contracting. It is your nervous system coordinating joints, strength, stability, and timing to interact with real world forces efficiently. When that coordination improves, movement feels smooth. When it does not, you see stiffness, compensation, and rising stress in places like knees, shoulders, and low back.

From there, we zoom out to adaptation: your body becomes what your environment repeatedly demands. Sitting for hours, avoiding a painful joint, never challenging balance, or consistently strength training and walking each push adaptation in a direction. That is why we stop obsessing over “perfect” exercises and start training abilities. The same squat can build confidence, rebuild trust after injury, improve bone density, or simply help you feel capable again.

If you want a body that supports the life you want to live, this conversation gives you a clearer lens and a more hopeful path forward. Subscribe, share this with someone who needs it, and leave a review with the ability you are training for right now.

Human Performance Series Setup

SPEAKER_00 0:01

Welcome to Live Transformed, the podcast from Transformed Health Initiative, where evidence-based truth meets real life transformation. Lead yourself, integrate health, value what matters, engage in the process. This is how you live transformed. And now here's your host, Adam Kelly.

SPEAKER_01 0:24

What's going on, everybody, and welcome back to the Live Transformed Podcast. I appreciate you for joining once again. If you listen to the first two episodes of this human performance series, we've laid a pretty important foundation here. So in the first episode, we talked about the question that changed everything for me as a coach. I realized that regardless of whether I was working with an athlete, a busy parent, someone trying to lose 100 pounds, a woman navigating perimenopause, or someone receiving or recovering from an injury, they were all trying to solve the same problem. They wanted a body that supported the life that they wanted to live. Then in the second episode, we took that idea a step further. We talked about why the goal isn't fitness for the sake of fitness. It isn't just weight loss just to see a smaller number on the scale. It isn't building muscles simply because bigger muscles look good. Those things matter, they absolutely matter, but they're valuable because of what they allow us to do. They expand our opportunities, they give us options, they improve our quality of life. Today I want to take it another step because once you understand why human performance matters, the next question naturally becomes how does the body actually get there? Why does training work? Why do we lose strength when we stop moving? Why does balance improve when we practice it? Why do some people seem to move effort effortlessly while others struggle with things that used to be easy? Most people think the answer is muscles or joints or flexibility or getting older, but I don't think that's where the conversation starts.

Daily Movement Problems You Ignore

SPEAKER_01 2:07

I think the conversation starts with a problem that every single human being has been solving every second of every day since the day they were born. And the crazy part is most of us haven't even noticed it. So think about your day so far. Not your workout, not your nutrition, just your day. Okay. So you probably got out of bed at some point. You stood up, you walked to the bathroom. Maybe you bent over to brush your teeth or to go to the bathroom. You reached into a cabinet, you walked down some stairs, you got into your vehicle, maybe you were carrying a cup of coffee, maybe you were carrying your breakfast, maybe you picked up your child, maybe you were unloading some groceries, maybe you sat down at a desk, maybe you've been on your feet all day. Here's what's fascinating. Every single one of those activities required your body to solve hundreds, if not thousands, of tiny movement problems. Problems you didn't consciously think about. How far did I shift my weight? How much force do I produce? How much force do I absorb? How do I stay balanced? How do I keep from falling? How do I get from here to there without wasting unnecessary energy? Your body isn't sitting there thinking through those questions consciously. Your body has become incredibly efficient at solving them. And when it solves them well, you barely notice. When it doesn't, that's when things become interesting. That's when stairs suddenly feel harder. That's when getting off the floor feels awkward. That's when carrying groceries starts bothering your shoulder. That's when your knee begins talking to you every time that you squat down or that you get up or that you do anything involving your knees. That's when balance starts becoming something you think about instead of something that you take for granted. The movement didn't change. The body's ability to solve the movement changed. That's human performance.

Gravity As The Constant Opponent

SPEAKER_01 3:57

Now, I want you to think about something that almost nobody thinks about, and that's gravity. Gravity is one opponent every human being shares. It doesn't care whether you're 25 or 75, whether you're an elite athlete or someone who's never stepped into a gym, whether you're male or female, whether you're healthy or you're recovering from a surgery, gravity is constantly asking your body one simple question. Can you handle me? Every second, every minute, every day, the moment you stand up, gravity begins pulling you toward the ground. Every step you take, gravity's involved. Every object you lift, gravity's involved. Every time you sit down, stand up, roll over in bed, reach overhead, pick up a grandchild, walk across your yard, climb into your truck, get off a step. Gravity is part of the equation. Now, here's why this matters. Most people think movement is simply about making muscles contract. But movement is actually your body's ability to successfully interact with the forces around it. Gravity is one of those forces, probably the biggest one you'll deal with every single day. So let me give you an example

Ground Reaction Force Explained

SPEAKER_01 5:03

here. Imagine that you're walking through the grocery store, okay? You take a step, your foot contacts the ground. Most people think that's where movement ends, but that something incredible is actually happening here. So the movement your foot, the moment that your foot presses into the floor, the floor actually pushes back. That's not an opinion, that's physics. It's something that's called a ground reaction force, okay? Every time that you push into the ground, the ground pushes back with an equal amount of force. Without that, you couldn't walk, you couldn't jump, you couldn't run, you couldn't stand, you couldn't even stay upright. The floor is literally helping you move. Now here's why human performance starts becoming really interesting. Your body has to know what to do with that force. Can it absorb it? Can it redirect it? Can it create stability from it? Can it help you help to produce the next movement? When those things happen efficiently, movement feels smooth. And when they don't, that's often where stiffness and compensation and poor balance or just unnecessary stress in general begins to show up. Notice I didn't say injury, okay? Because we're not talking about diagnosing problems. We're talking about understanding the demands that life places on the body. That's a whole different conversation, all

Exercise As Questions Your Body Answers

SPEAKER_01 6:16

right? So this next realization completely changed how I look at training altogether. So for years, I thought muscles were the goal. I thought that strength was the goal, I thought that movement quality was the goal. Now, now I think that all of those are actually just responses, not the objective. Your body wakes up every day asking one question: what is required of me today? That's it. If you spend most of your day sitting, your body adapts. If you spend most of your day walking, your body adapts. If you repeatedly lift heavy objects, your body adapts. If you never challenge your balance, your body adapts. If you're constantly exposed yourself to new physical challenges, your body adapts. The body's always responding to the demands placed on it. Not because it's trying to build muscle, not because it's trying to improve mobility, not because it's trying to increase endurance. It's simply trying to become better at solving the problems it repeatedly encounters. That's one of the biggest mindset shifts I've had over the years. We often think that we're training muscles. I don't really think we are. I think we're presenting the body with problems. And over time, the body becomes better at solving problems. The ability to solve increasingly demanding physical problems, that's adaptation. That's where we're going to pick up in the next part of this conversation. Now, if that's true, if your body is constantly adapting to the problems it repeatedly has to solve, then I think it changes the way we should look at exercise altogether, don't you? Because I don't believe exercise is the goal. I don't even believe an exercise is the thing we're actually training. I think exercise is simply the environment where we practice solving physical problems. Think about that for a second. Every exercise you do is asking your body a question. Can you control this position? Can you stay balanced? Can you absorb this force? Can you produce enough force? Can you co cooperate and coordinate all of these joints and muscles together? Can you stay stable while something around you is changing? That's all an exercise really is. It's a question. And your body answers it. Sometimes the answer is yes, sometimes it's not yet. But every repetition, every single rep is another opportunity for your body to learn. That's why I don't get overly attached to specific exercises, or at least any longer. Because we're not training exercises, we're training abilities. That's a huge difference. If two people are doing a squat, they may look like they're doing the exact same movement, but they could be solving completely different problems. One person may be learning how to control their balance, another may be building strength. Someone else may be improving confidence getting down on the floor. Another person may be increasing bone density. Someone else may be simply rebuilding trust in a knee that they've been afraid to load for years. Same exercise, different problem, different adaptation, different purpose. And that's one of the biggest shifts we've made at THI. We don't start by asking, what exercises should this person do? We start by asking what problem are they trying to solve. Once we can understand the problem, the exercise almost picks itself. Think about learning to ride a bike. Nobody becomes better at riding a bike because someone explained how to balance. You become better because the nervous system experienced thousands of tiny corrections. You lean too far one way, you correct. You lose balance, you recover, you wobble, you adjust. And you're probably gonna fall a whole lot of times as well. But eventually, you stop thinking about balance altogether. You simply ride the bike. Your body solved the problem, and movement works the same way. The body learns through experience, not memorization, not motivation, experience. That's why I often tell clients, your body doesn't care what you know, it cares what you repeatedly ask it to do. And this is one of the reasons I think so many people become frustrated. They judge themselves based on today's performance. Instead of appreciating what their body's been learning over time that they've been on this journey, they'll say, I'm just not coordinated, I'm too stiff, I've never been athletic, I'm getting older, I just can't do this, I'm not gonna be well, maybe, but maybe your body simply hasn't had enough opportunities to solve that particular problem yet. That's a much more helpful way to look at it, and I like to stay on the positive side. Plus, problems can be practiced, abilities can be developed, capacity can grow. That's adaptation, and that's what we're after. Now, I want you to be careful here,

Use It Or Lose It Adaptation

SPEAKER_01 11:12

okay? Because adaptation doesn't always move in the direction we want. We need to be very clear about this. Your body doesn't know the difference between a good adaptation and a bad adaptation. It simply responds to repeated demands. If you spend 10 hours a day sitting, your body adapts. If you never challenge your balance, your body adapts. If you avoid using a painful shoulder for months, your body adapts. If you're consistently exposing your body to progressive strength training, your body adapts. If you regularly challenge your cardiovascular system or your cardiorespiratory system, your body adapts. If you routinely practice getting on and off the floor, your body adapts. The body isn't judging, it's responding. That's one of the most fascinating things about being a human. We're incredibly adaptable. The question isn't whether you're adapting, the question is what are you adapting to? And I think that's that's why I think the phrase use it or lose it actually has a lot of truth behind it. Like I'm not, I don't hate that phrase. There's a lot of phrases I don't get behind in fitness, but I totally agree with the use it or lose it mentality. Not because your body is trying to punish you, because it's efficient. The human body is remarkably efficient. If it determines that a certain ability isn't necessary anymore, it gradually re- reallocates its resources, okay? It shifts what is a priority now. Think about someone whose job suddenly becomes completely remote. You know, they're working from home now, they stop walking as much, they stop climbing the stairs that they normally climbed at work, they stop carrying things like carrying their bag or their lunch or their drinks into the office every day. They spend more time sitting because they're not having to go to work. It's not surprising if six months or a year later they notice that they're more deconditioned. Their body simply adapted to the new environment. Now, think about someone who begins strength training consistently. They start walking every day, they improve their sleep, they become more active. Over time, the body adapts too. Same human body, different demands, different outcome.

Movement As Information Not Calories

SPEAKER_01 13:20

This is why I also believe movement should never be reduced to calories burned. Because movement is information. Every step tells your body something, every lift tells your body something. Every carry, every reach, every rotation, every change in direction, your body is constantly collecting information about the world around it. And then deciding how it prepared it needs to become in order to accomplish what you are making it do. That's why I love strength training, not because lifting weights is magical, although I love it, but it's because it's one of the safest and most effective ways we have to intentionally expose the body to meaningful physical challenges. We're giving the body problems to solve on purpose before life forces us to solve them. And I think that's a really important distinction because life doesn't schedule its challenges around when we're ready, am I right? Life just happens. You trip, you catch yourself, you move furniture unexpectedly, you help someone who's fallen, you carry your sleeping child to bed, you spend all day working in the yard, you climb 10 flights of stairs because the elevator's broke. The question isn't whether life will ask your body to perform. The question is, will your body be prepared when it does? That's why we train, not for the gym, for

Your Body Is Not The Enemy

SPEAKER_01 14:41

life. Now, if you stay with me this long, I hope one thing has become really clear. Your body is not your enemy. I think a lot of people unintentionally begin seeing it that way. My body won't lose weight, my body's getting old, my body hurts, my body just doesn't want to do what it used to do. My body's always working against me. I've heard these statements hundreds of times over the years. And honestly, I've probably said some of them myself after dealing with my injuries and setbacks, so I can totally relate there. But today, I encourage you to look at this a little differently. Your body isn't working against you, your body's responding to the environment you placed it in. That's a huge distinction. Because if the body can handle and adapt in directions we don't want, it can also adapt in directions we do want. That's one of the most hopeful things about being human. We're not finished products, we're adaptable. Now that doesn't mean that adaptation happens overnight, okay? It doesn't mean that every limitation is going to disappear. It doesn't mean that every energy injury can be erased. Life leaves its mark on us, okay? This is just the reality of being human and living life. Some people have surgery, some people have arthritis, some people have injuries they'll manage for the rest of their lives. Some people have conditions that require them to approach training differently. Human performance isn't pretending these realities don't exist. It's giving a different question. Given the body you have today, how do we help you become the most capable version of yourself? That's the question. Not how do we make you 20 years old again? Not how do we make you move exactly like someone else? Not how do we chase perfection? How do we improve from here? Because improvement is always relative to the person standing in front of us.

Why One Size Training Fails

SPEAKER_01 16:33

One of the biggest mistakes I see in the fitness industry has made, or you know, the problems that have been created by the fitness industry is convincing people that everyone should train the same way. That it's just the human body is so relatable and we're all 99.8% the same. So we should all just be able to train the same. That there's one perfect exercise, that everybody needs to be doing a specific exercise, or there's one perfect program, or a perfect way to squat, or a perfect way to deadlift, or a perfect way to move. I honestly don't believe any of that. I believe there are principles. I believe that there's goals. I believe there are demands that life places on the human body, but how we help someone meet those demands, that is individualized because no two people are solving the exact same problem. So take somebody, or take something as simple as just like getting off the floor, okay? For one person, it's effortless, right? For another person, though, it's one of the hardest things they'll do all day. Think about that. We got to put ourselves in other people's shoes. The movement is the same, the demands are the same, the preparation's the same, the confidence is different, the capacity is different. That's why coaching matters. Not because coaches own information. You can find information anywhere. I mean, we got Chat GPT now, we've got all of the technology, we've got Google, AI, all these things popping. You can find the information if you want it. Coaching is about understanding the person in front of you, understanding what life is asking of them, understanding where the gap exists, then helping them close the gap. That is human performance. At THI, we often say that we're trying to help people build a body that supports the life they want to live. Hopefully, now that phrase means a little bit more than it did at the beginning of this series because the body isn't built by accident. That's why I like to say went on purpose. It's built through repeated exposure to meaningful challenges. It's built through movement, through strength, through recovery, through nutrition, through walking, through sleep, through consistency, through gradually asking your body to solve slightly bigger problems than it solved yesterday. That's how adaptation works. That's how resilience is built. That's how confidence is built, not all at once, one challenge at a time. And here's

Small Choices Build Capability

SPEAKER_01 19:06

something I think is incredibly encouraging. The body is always paying attention. Every walk matters, every workout matters, every good night's sleep matters, every meal matters, every decision is a vote. Not in a moral sense, not because you have to be perfect, but because every choice is information. You're constantly telling your body, this is the kind of human I need you to become. And your body's listening. That's incredible when you really stop and think about it. Maybe that's why I love coaching so much, because coaching isn't really about writing workouts. It isn't about counting calories, it isn't about chasing numbers. Those things are important, but they're not why I do this. What I love is watching people slowly realize they're capable of more than they believed. Watching someone confidently get off the floor after years of avoiding it, watching someone carry something that used to intimidate them, watching someone travel without worrying whether their body's gonna hold them back, watching someone realize they have energy at the end of the day, watching someone stop defining themselves by what they can't do, and start getting excited about what they can. That's why I believe human performance matters. Not because everyone needs to become exceptional, because everyone deserves the opportunity to fully participate in their own life. So as we wrap up today, I want to leave you with one thought.

Train For Life Then Next Steps

SPEAKER_01 20:31

Life is going to keep asking your body questions. Sometimes those questions are small, sometimes they're enormous. Can you carry this? Can you recover from this? Can you stay balanced here? Can you keep going? Can you adapt? Can you remain resilient? The questions never stop. The beautiful part is neither does your ability to improve your answers. That's what training is really about. It's not punishment. It's not earned food or earning food. It's not chasing exhaustion. It's preparation. Preparation for the life you're living today and the life you hope to keep living for decades to come. Because at the end of the day, we don't train exercises, we train abilities. We don't build bodies just to look different. We build bodies that allow us to live differently. That is what human performance is all about. So I appreciate you guys dearly for spending part of your day with me. In the next episode, we're going to talk about something that I think keeps a lot of people stuck without them ever realizing it. We're going to explore why most people focus on the wrong problem. Because when you solve the right problem, everything else starts moving in the right direction. So until next time, do something good for yourself, something good for your health, something good for those you care about. And whatever you do, make sure you live transformed. Talk at you next time.
