If this one study is right, then decades of exercise advice for women was built on an untruth.

A new paper in Nature Cardiovascular Research shows women get far more heart protection with far less exercise than men.

Yet the world kept repeating “150 minutes a week” as if the female heart were just a small version of a male one.

It wasn’t science holding us back. It was the assumption that one body could stand in for everyone’s.

If this guideline was wrong for women… what else in medicine do you now question?
