The classes are being targeted at girls in Bedfordshire who do are not interested in traditional sports.
Daniel Gill, of Active Luton, the trust which runs local sports and leisure facilities, said: "You tend to burn about 400 to 600 calories an hour in these classes.
"You are working on coordination, balance, cardio vascular, stamina.
"You can vary and change the intensity so it matches other sports quite well.
"There is no segregation on ability. Even if they know they cant do all of it, they can try anyway. And it's a good way of introducing them to a gym."
