Perimenopause and postmenopause are not the same thing
These two get collapsed into "menopause" constantly, and the distinction is not academic: the same training produces different results depending on which stage you are in. This is one of the few places where the evidence genuinely supports treating women differently — and it is not the place most advice focuses on.
The finding
A 2025 review found that during perimenopause, strength training, endurance work and Tai Chi did not improve bone density or lean mass — whereas in early postmenopause, strength training did. Same intervention, different stage, different result.

What this does not mean
It does not mean skip training during perimenopause. Strength work has a large evidence base for all-cause mortality, function and metabolic health that has nothing to do with bone density, and none of that goes away. It means the specific expectation — that lifting through perimenopause will protect your bone density — is not currently supported, and it is worth knowing that before you judge the results.

Sprint performance declines earlier than you would expect
Sprint performance declines faster in women after 30 than VO₂ max does, which is the argument for treating sprint interval work as a priority rather than an optional extra — well before menopause is a consideration at all.
Hormone therapy — inform yourself, then see a clinician
Hormone therapy is the most effective treatment for hot flashes, roughly a 75% reduction versus placebo, and improves sleep specifically in women who have vasomotor symptoms. This is a medical decision that belongs with a doctor who knows your history; it is here so you know it exists, not as a recommendation.

And within a cycle?
Different question, different answer: cycle phase does not meaningfully change training adaptation. Life stage does. Phase does not.
Common questions
Does strength training protect bone density in perimenopause?
A 2025 review found that during perimenopause, strength, endurance and Tai Chi did not improve bone density or lean mass. In early postmenopause, strength training did. The stage matters, and the expectation should be set accordingly.
Is perimenopause the same as menopause?
No, and the distinction changes what training does. Perimenopause is the transition, with fluctuating hormones; postmenopause follows it. A 2025 review found strength training improved bone density and lean mass in early postmenopause but not during perimenopause.
Should women over 30 do sprint training?
Sprint performance declines faster in women after 30 than VO₂ max does, which is the argument for treating sprint intervals as a priority rather than optional.
