The Right Amount of Stress is Key: Understanding Stress, Recovery, and How Our Bodies Adapt When We Get This Right

   When people first walk into the clinic, we often hear the phrases “I just want this to go away” or “I want to be able to do x,y,z  pain free” or “I just want to get stronger” (this one is the best to hear!) These are all extremely valid for different reasons – why wouldn’t you want to be out of pain? It’s uncomfortable. When something hurts, you want relief. But if our only goal is to calm pain as quickly as possible, we sometimes miss the bigger opportunity — building a body that is more resilient and more capable than it was before the injury or pain ever started.  The same can be said for wanting to get stronger – who doesn’t want to get stronger? The hard part is, getting there means you must put your body through some safe stress and discomfort to train it to adapt to build to a new baseline.

To understand how that happens, we have to talk about one of the most important principles in the human body and performance: Stress, Recovery, and Adaptation.

Your body cannot change without being challenged. At any given moment, you have a current physical capacity — we call this your baseline (dotted line on chart).  It’s what your muscles, tendons, joints, and nervous system can tolerate. If you stay below that line and never meaningfully challenge it, nothing changes. Muscles don’t get stronger. Tendons don’t become more resilient. Your tolerance for lifting, running, squatting, or playing your sport doesn’t increase. Not only that, but it lowers your baseline for just basic daily functional tasks – how many steps you can take in a day, how long you can do yard work, or being able to babysit your grandkids for a weekend. In short – if you find yourself constantly battling pain, injuries, or “flare ups” – your base line is probably too low for what you want to do.

When we introduce the right amount of stress through progressive strengthening and controlled loading, your system temporarily dips – AKA we place stress on your body. You might feel muscle fatigue or soreness. Sometimes symptoms even increase slightly for a short period of time. That dip can feel discouraging if you’re expecting a straight upward path. But that dip doesn’t usually mean that we got something wrong. It’s part of the process.

If the stress was appropriate (not excessive, but intentional) your body recovers. And during recovery, something powerful happens - adaptation. You don’t just return to what your baseline was, you raise it. The muscle fibers remodel. Tendons increase their load tolerance. Your nervous system becomes more efficient and less protective. Movements that once felt threatening begin to feel manageable. Over time, those small waves of stress and recovery trend upward, raising your overall capacity and “baseline”. You are building new baselines!

This is why rehab rarely feels linear. It looks much more like a series of waves than a straight arrow. You challenge the system, it dips, it recovers, it adapts. Then you challenge it again at a slightly higher level. Some weeks feel strong and confident. Other weeks feel heavier.

Because of this, rehab should feel somewhat challenging. Once we get through the basics of how to brace or stabilize, we feel things in the right places, and we’re moving with confidence and good form – the rehab process really should feel challenging. On the other hand, if everything feels like it’s flaring you up beyond control, the stress may be exceeding your current capacity. The key is finding the sweet spot — enough stimulus to create change, but enough control to allow recovery. This is where we as Doctors of Physical Therapy come in. Our expertise doesn’t lie in being able to diagnose and giving you 3 basic exercises. Our true expertise lies in the art of navigating what’s too little, what’s too much, and what’s just right – knowing that every single human that walks through the door has a different “sweet spot” based on their history, lifestyle, nervous system, etc.

This is also why one exercise or passive treatment alone is rarely the full solution. Soft tissue massage, dry needling, and manual therapy absolutely have value. They can calm symptoms, improve mobility, and help settle a sensitive system. We use this often in very early plans of care. But they do not build long-term capacity by themselves.

The empowering part of this process is realizing that you are not fragile. Your body is not broken beyond repair. It is adaptable. That means you are not dependent on someone “fixing” you. We bring expertise in movement assessment, tissue healing timelines, and progressive load/stress management. But you are the one who creates adaptation through consistent effort.

The ultimate goal of rehab isn’t just short-term relief. It’s confidence. It’s being able to pick up your kids, train hard, return to your sport, or go through your day without constantly managing or thinking about symptoms. That kind of resilience doesn’t come from staying comfortable or passive treatment. It comes from intentionally and safely challenging your system, allowing it to recover, and repeating that cycle over time.

The coolest part? Your body is not broken. If you put it in the right environment – it adapts.

And when it adapts, you don’t just feel better. You become more capable.

If you’re sick of guessing if you’re doing the right things, doing too much or too little, or questioning if the discomfort of your rehab process is productive discomfort – this is quite literally where our expertise lies. We’re meant to act as a guide so you can feel more confident and tweak the plan ever so slightly as time goes on to make sure you’re on the right track.
