YMCA gymnastics instructor Denise Johnson leads students in the Cheer Tumblers class, which teaches gymnastics for cheerleaders, at the YMCA of York Gymnastics Academy Friday, July 20, 2012. Johnson says competitive cheer has evolved, requiring much of the same skills as gymnastics. "Fifteen years ago I wouldn't have considered this a sport," she said. Proponents of competitive cheer say it should be an Olympic event like gymnastics, which is one of the featured competitions in the 2012 London Olympics which starts July 27.
