How wide is yours?
Happy Monday!
With the awesome power of the algorithm, my feed is full of movement professional and normal folk trying to solve everyone's problems.
One thing that sticks out to me is how many people talk in absolutes.
“I need eight hours of sleep or I’m wrecked.”
“Training your fascia will turn you into an athlete.”
“Lifting heavy causes injury.”
What I rarely hear is curiosity about range.
Not a perfect number. Not a magic rule. Just an honest understanding of what your body can tolerate on the low end, what it can tolerate on the high end, and how well it can move between the two.
That idea stuck with me after listening to a recent conversation from Dr. Mike T Nelson, where he described what he calls human dynamic range. In simple terms, it is your capacity to operate across highs and lows, and your ability to oscillate between them without breaking down. Heart rate, workload, fuel, sleep, stress, even focus. The principle shows up everywhere.
We love linear answers. One target. One number. One protocol. But the human body does not work that way.
It works in ranges.
From a biomechanical standpoint, think about tension or in a training environment we call it "load."
There is a low end where the body is underloaded and starts losing tolerance. Muscles shrink. Tendons get less stiff. Joints lose awareness.
Then there is a high end where the load exceeds what the system can absorb. That is where flare ups, injuries and a multitude of other symptoms can live.
Health is rarely found at either extreme! It is built by spending most of your time inside a tolerable range, then occasionally nudging the edges to expand it.
Physiology follows the same rules!
Fuel is a great example. Some people swing hard to one side and decide carbs are the problem. Others rely on them constantly and crash without them. The reality is most people have a usable range of fuel sources, but they have lost access to part of it. Spending too much time at one end shrinks the other.
Sleep works the same way. If you can only function when everything is perfect, that is not resilience. That is fragility. On the flip side, living in chronic short sleep and stress is not toughness, it is erosion. A healthy system has a range of sleep durations it can tolerate, and more importantly, the ability to recover after a short night or a hard week. That capacity is trained, not gifted.
Psychologically, range matters even more. People who feel best only when life is calm tend to unravel when pressure shows up. People who live in constant grind mode eventually burn out. Emotional and mental health are not about eliminating stress or chasing constant stimulation. It's about being able to downshift and upshift when needed, without wrapping up your identity to either end.
Again, most of y'all miss this part... Spending too much time at either end of a range does not just stall progress, it shrinks the range itself!
The goal is not balance in the way people usually mean it. The goal is range with control.
The awesome part is though that over time, most ranges can be expanded! Slowly. Intentionally.
Too many people try to jump straight to the edges without earning them. They want high output without a base. They want restriction without flexibility. They want resilience without exposure.
Even if you're not an athlete yourself you see this clearly in elite athletes. They are not fragile. Their ranges are massive. They can tolerate high workloads and still recover. They can handle imperfect sleep during travel. That does not happen by accident.
The same concept applies to longevity. I have clients in their seventies who are not trying to be athletes, but they are trying to stay adaptable.
So here is a simple place to start this week: Pick one system and get curious about your current range.
1) Workload. What is the lowest amount of movement you can do before stiffness and pain show up? What is the highest you can tolerate before recovery suffers?
2) Fuel. What foods feel easy to use? Which ones consistently leave you foggy or flat?
3) Sleep. What happens after six hours? After eight? After a late night?
4) Stress. How quickly can you calm down after a hard day?
Do not judge it. Just observe it. Then ask a better question.
Not “How do I optimize this?” but “How do I widen this slightly without blowing myself up?”
That is exactly why our process at Charge is built the way it is. We are not chasing perfect protocols. We are rebuilding lost capacity. We expose people to just enough load, just enough stress, just enough challenge to expand their usable range without overwhelming the system. Over time, life gets easier not because it is softer, but because you are more capable!
If this email hit a nerve, it probably should. Most people are not broken. They are just living inside a very small range.
If you want help expanding yours, that is what our core programs are designed to do. Not quick fixes. Not band aids. Just a smarter way to rebuild resilience across your body and nervous system.
Reply to this email with one word: workload, fuel, sleep, or stress. I want to know which range feels tightest for you right now.
Take control of what you can, today!
