"For National Women's Health Week, the Office on Women's Health sponsors an 8-week national physical activity challenge called the WOMAN (Women and girls Out Moving Across the Nation) Challenge." There were 10,800 free pedometers available on a first-come-first-served basis for participants who requested one during registration, but now they have all been given away.

It began Sunday, May 13th, Mother's Day,
to kick off National Women's Health Week.
Let's get moving!

Ce challenge est à la fois l'occasion d'encourager la population à bouger et faire des exercices réguliers, et de faire découvrir les USA. Vous apprendrez tout sur le Challenge dans les FAQ
