"Below the Belt" is a lower body workout that doesn't use dumbbells or barbells. Instead, Kelly and Kitty use an Optional 8lb vest and 2.5lb ankle weights to add intensity. This 30 minutes consists of 15 minutes on your feet and 15 on the floor. The half and half format is not only time efficient and effective, but its also less taxing on the knees. *For those with wrist issues the weighted vest is great for the standing portion...on the floor go down onto your forearms instead of your hands.
