When people hear “hormones,” they usually think of one half of the population, and usually one narrow slice of that person’s life — periods, menopause, mood swings. But hormones aren’t a women’s health topic. They’re a human topic. Insulin, cortisol, testosterone, growth hormone — these systems are running in the background for every single person, every single day, shaping your energy, your weight, your mood, and your long-term health.
And one of the simplest, most well-supported ways to support that whole system? Movement.
The Master Hormone: Insulin
Insulin’s job is to manage blood sugar — but its influence doesn’t stop there. Because insulin sits so close to the centre of your metabolic system, when it’s not working efficiently (a state called insulin resistance), the effects ripple outward into other hormone systems: energy regulation, appetite signalling, inflammation, and — for many women in particular — reproductive hormone balance.
This is exactly why insulin sensitivity has become such a central focus in modern health conversations, well beyond diabetes prevention.
What the Research Actually Shows
The research on exercise and insulin sensitivity is some of the most consistent in exercise physiology. Studies have found a clear dose-response relationship: the more consistent movement someone does, the better their insulin sensitivity tends to be — and this relationship holds true regardless of age or gender. Interestingly, even relatively modest amounts of weekly exercise have been shown to produce a measurable improvement, well below what most public health guidelines recommend as a target.
It’s worth being upfront about the nuance here too: some research suggests that improvements in insulin sensitivity from exercise can be transient — meaning consistency over time matters more than a single block of training. This isn’t a “do a 6-week program and you’re set” situation. It’s an ongoing practice, much like brushing your teeth.
For Women: Insulin, Cycles, and PCOS/PMOS
For women, this insulin conversation often intersects directly with hormonal health. Conditions like PCOS/PMOS are strongly linked to insulin resistance, and exercise is consistently recommended as a foundational, first-line strategy alongside nutrition. Cycle-related hormone fluctuations (like the oestrogen and progesterone shifts across the month) can also influence how the body handles blood sugar, which is part of why some women notice cravings, energy dips, or mood changes at certain points in their cycle.
Having completed further study specifically in women’s health, this is an area Megan find’s genuinely fascinating — insulin regulation isn’t a side note in female hormonal health, it’s often central to it.
For Men: Testosterone, Cortisol, and Recovery
Men aren’t left out of this picture. Resistance training in particular has been shown to trigger acute hormonal responses — including short-term increases in testosterone and growth hormone — immediately following a session. The research on whether this translates into meaningfully higher resting hormone levels long-term is more mixed and still developing, so it’s worth being cautious about overstating it. What is well established is that regular strength training supports healthy body composition and insulin sensitivity, both of which play a supporting role in overall hormonal health — alongside adequate sleep and stress management, which heavily influence cortisol.
What This Looks Like Practically
You don’t need to train like an athlete to get the benefits here. The research consistently points to:
- Consistency over intensity — regular movement beats sporadic, extreme sessions
- A mix of resistance and cardiovascular exercise — each contributes differently to insulin sensitivity and hormone regulation
- Something sustainable — because the benefits fade if the habit does
If you’re starting from a low base, even short, regular walks or basic strength sessions are a legitimate starting point, not a “lesser” option.
Where Your Nervous System Fits In
Here’s the piece that often gets left out of the hormone conversation altogether: your endocrine system doesn’t operate independently of your nervous system. Hormone regulation — including the stress-response pathways that influence cortisol — is closely tied to how well your nervous system is functioning and adapting.
This is where a vitalistic approach to chiropractic care comes in, not as a replacement for exercise, nutrition, or medical care, but as a complementary layer of support. Helping your nervous system function and adapt well is part of the broader picture of hormonal health — alongside the movement habits we’ve talked about here, and in partnership with your GP or specialist for anything requiring medical management.
The Takeaway
Hormone health isn’t a “women’s issue” or a “men’s issue” — it’s a whole-body, whole-system conversation, and movement is one of the most accessible levers you have to influence it. Start where you are, aim for consistency over perfection, and remember that supporting your body well means looking at the whole system — nervous system included.
