The purpose is to evaluate the feasibility of a 12-week exergaming dance program for adolescent girls. This study combines dancing, video games, and a full body work-out to test if video games can increase physical activity and promote healthy weight in adolescent girls. We hypothesize that girls who play the dance exergames, versus those in the control group, will lose weight, decrease body fat and visceral fat, improve cardiovascular health, increase physical activity, and improve psychosocial health including self-confidence and quality of life.
