Girls are being putting off exercise for life by PE classes, because of grubby school changing rooms and embarrassment at getting sweaty in front of boys.

Research by Loughborough University shows half feel they're forced into doing team sports, and many girls said they wanted to try activities like dance, but it wasn't an option.

The Women's Sport and Fitness Foundation says schools should offer more female-friendly activities such as zumba and roller-blading.
