In this segment, JJ Virgin explains how chronic overtraining keeps cortisol levels chronically elevated, which in turn raises fasting blood sugar, breaks down muscle, and promotes visceral (belly) fat storage. To counteract these effects, she recommends a balanced exercise regimen for mid‑life women: resistance training 2–4 times per week to build and preserve muscle and improve stress handling; short, properly performed HIIT sessions (10–20 minutes) twice a week to burn fat without over‑taxing the adrenal system; and abundant daily non‑exercise activity (NEAT) such as walking, stair climbing, and fidgeting, which helps lower post‑meal blood sugar spikes and burns fat with minimal adrenal stress. The overall message is to work out strategically—supporting muscle growth and metabolic health—rather than over‑training, which harms cortisol balance and body composition.

If you are chronically overtraining and not giving your body time to adapt, this can lead to chronically elevated cortisol. And that is a problem. Chronically elevated cortisol does a couple really problematic things. Number 1, it's gonna raise your fasting blood sugar cuz your body thinks you're just running away from a tiger all the time. You don't want it high all the time. Number 2, it's also catabolic, but not just for fat, it's breaking down muscle. So that's problematic. And number 3, we have cortisol receptors in our belly area, and that's where we get that visceral adipose tissue. If we are higher cortisol, we all tend to store more fat in our visceral adipose tissue and in our belly area. And that's what we want to avoid because that's a really damaging fat. So the reality here is you want to work out for sure, but you want to work out in a way that is going to support your body holding onto, or better yet, building muscle. And that means resistance training. 2 to 4 times a week. You want to work out so that your body learns how to handle stress better and recover from it and burn off that visceral adipose tissue. And what's great for that is 2 days a week of HIIT training. And this is not a lot of a workout. If you can do HIIT training for an hour, it's not high-intensity interval training. That's something else. HIIT training done correctly is going to be 10 to 20 minutes. And then you want to be doing just a lot of movement all throughout the day, that non-exercise activity thermogenesis. It turns out when you look at your metabolism in that third area of activity, People think the big lover is exercise, but the real lover is just moving more all throughout the day. Fidgeting, pacing, taking the stairs, parking farther away, it all counts. So in those long, slower movements, like going out for that walk, not only help lower the blood sugar response to a meal, they also are the best ways to just burn off that fat without taxing your adrenals.
