Femmi empowers women to move sustainably.

Here to change sport. Period.

Femmi founders Lydia and Esther grew up as elite female athletes. We faced pressure to train in a way that was right for men, but not for us. We didn't know how our female physiology worked. We were told to train more, eat less and lose weight. Ultimately, our health and performance suffered. We lost our menstrual cycles, and we nearly lost running.

It's time that women learn more about their bodies and how to move in a way that gives them confidence. We've brought together a team of women's health experts and running coaches with a proven track record and a strong vision.
