The Monkey Bar Gymnasium, a Madison, WI, health club specializing in playground style routines that incorporate running, jumping, crawling, and climbing, proves you don't need cardio machines to slim down. Of its members, 85% work out 3 times a week — triple the national average — and they drop an average of 17 pounds of fat in 2 months. Try these grownup versions of favorites from your youth.
