Our mission
To bring the science, training, and community elite female athletes rely on to every girl and woman in sport, so she can train smart, stay healthy, and keep growing wherever she plays.
Our vision
Every girl, everywhere, knows sport is for her and has what she needs to stay in the game for as long as she loves it.
Why we exist
Girls are leaving the game too soon.
Girls are leaving sport faster than boys, and most of the science that guides training was never built around women. We're changing both.
By age 14, girls drop out of sports at twice the rate of boys.
Women's Sports FoundationBy high school, roughly one in three girls doesn't feel sport is for someone like her.
