Almost 80% of teenage girls are unhappy with their bodies. It's one of the biggest reasons they're not moving enough. In fact, worldwide, only 15% of teenage girls are doing enough physical activity. And in lower income households and ethnically diverse communities, it's even less.

We want to change this story. With your support we can empower girls to start moving more, and to try everything from street dance and skateboarding to boxing and yoga. We plan to design and pilot new school programmes. To support community groups to reach new girls. And to transform the online world to encourage and inspire girls, not shame them.

The more funds we raise, the more girls we can reach in communities across the US and UK.

So please, help us create a world of active, healthy, happy girls and donate now.
