Step aerobics blended with kick boxing. It’s the perfect combination — a step is a natural way to add vertical intensity to boxing’s usual lower-body moves. The result? You’ll burn more fat as you tone your legs and buttocks. Kelly Coffey-Meyer’s add-on cuing and smooth transitions make it totally doable. She always introduces a new punch exercise with a basic step combo, or demos a new step sequence with a simple punch combo. The first workout is a little less choreographed. The second is slightly faster-paced with more varied combinations. Both programs use the space around the bench for wider-ranging patterns.
