Lindsey Bomgren and Brigid Titgemeier debunk the idea that HIIT wrecks women's hormones. Done right with proper fueling, HIIT boosts VO₂ max and grip strength, two of the strongest longevity predictors. The catch: it's a stressor, so balance it with recovery when life stress is already high.

You hear about HIIT training and how it can be bad for your hormonal health or how it can spike your cortisol. And I'm here to tell you that a well-fed, healthy woman, HIIT training is not going to impact her hormones when done in the right volume. It's just like anything, right? So HIIT training actually is one of the best ways to raise your VO2 max. VO2 max and grip strength are the 2 largest indicators of longevity. So we do need to pay attention to HIIT training, but we also need to be fueling appropriately for it.
Fueling appropriately for it and then not overdoing it when you're in very stressful periods of life because it is a hormetic stressor like anything else. And if you have the wrong balance of hormetic stressors, then it will end up creating a level of burnout for a lot of women.
