Some JUMPING is just what you need sometimes to add to your weekly routine. In this class, the Jumpboard converts the reformer into a horizontal jumping machine, taking gravity out of the equation. These jumps are of low-impact, even lower than those on the trampoline, which makes the class joint- friendly and fun, especially when you are jumping on the moon, as light as a feather. It's a great class for burning calories, working on your legs when these springs are heavy, and on your abs when the spring is light. The class consists of a mixture between a cardio jumping and a strengthening targeted component.
