Movement is Medicine

And it Doesn't Have to Feel Like Punishment

I want to reframe something that I think a lot of people have gotten wrong about exercise, including, at some point, me.

Somewhere along the way, movement became synonymous with suffering. With intensity. With earning your food or burning off the weekend. The messaging around exercise has been so relentlessly focused on aesthetics and performance that a lot of people have quietly opted out. If you grew up in the 80's and 90's, you know what I mean. People opting out is not because they're lazy, but because the version of exercise that has been sold to them doesn't feel sustainable, enjoyable, or even particularly relevant to how they actually want to feel in their body.

Here's what I tell my patients: movement is medicine. Not metaphorically, literally. It is one of the most powerful interventions we have for metabolism, sleep, mood, hormonal regulation, cardiovascular health, and longevity. No supplement comes close to what consistent movement does for the human body. But the dose matters, and more is not always better. And the best movement practice you can have is one you'll actually do consistently.

WHAT MOVEMENT DOES FOR YOUR METABOLISM

Metabolism is one of those words that gets used loosely, usually in the context of it being fast or slow, and usually as an explanation for why someone can or can't lose weight. But metabolism is much bigger than that. It's the sum total of every chemical process your body runs to produce energy, repair tissue, regulate hormones, and keep you alive. Movement influences nearly all of it.

When you exercise, your muscles contract and demand fuel. To meet that demand, your body pulls from glucose and stored glycogen, and over time, with consistent movement, it becomes more efficient at doing so. Insulin sensitivity improves, meaning your cells respond better to insulin and glucose gets used more effectively rather than stored. This matters not just for weight, but for energy levels, inflammation, hormonal balance, and long-term metabolic health.

Muscle tissue itself is metabolically active. It burns energy at rest in a way that other tissues don't, which is one of the reasons that building and maintaining muscle through movement, particularly resistance training, has such a significant impact on how the body manages energy over time. This becomes especially important as we age, because we naturally lose muscle mass from our mid-thirties onward if we're not actively working against that trend.

But here's the part that often gets overlooked: you don't need to be doing intense exercise to see meaningful metabolic benefits. Walking, gentle yoga, and low-intensity movement all improve insulin sensitivity, reduce inflammatory markers, and support metabolic function. The idea that exercise only counts if it's hard is one of the most persistent and unhelpful myths in health culture.

Movement is a dial, not an on-off switch. Turning it up a little, consistently, does far more than occasional bursts of intensity followed by weeks of nothing.

THE MOVEMENT THAT FEELS LIKE TOO MUCH — AND WHY IT BACKFIRES

There's something worth naming here, especially for anyone who has a history of overdoing it, or who has been told by a doctor or a wellness article that they need to exercise more but finds themselves consistently unable to follow through.

For people with HPA axis dysregulation, the cortisol pattern we talked about in the last series, intense exercise can actually make things worse. High-intensity training is a significant stressor on the body. Done in the right context, the body adapts and benefits. Done on top of an already dysregulated stress response, it adds load to a system that's already struggling to find its rhythm.

This is not an excuse to avoid movement. It's an argument for choosing the right kind. If you're exhausted, sleeping poorly, and running on fumes, a daily walk and a restorative yoga class will serve your nervous system far better than a punishing HIIT session. Meeting your body where it is, rather than where you think it should be, is not a compromise. It's good medicine.

We'll get into the sleep and nervous system connections in the next post. But the thread running through all of it is the same one that runs through everything I've written in this series: the body is not your enemy, and the goal is always to work with it rather than against it.

Next up: how movement directly affects your sleep quality and nervous system regulation, and why what you do during the day matters just as much as what you do at bedtime.
