Shape: Bikini Body Camp Redefining Workout (2006)

These are two fun and challenging cardio sculpt workouts. The first alternates weights and cardio movements in a circuit to keep aerobic intensity. Although you can change the intensity based on your weight choices, the overall effect is to keep your heart at a steady, but elevated, rate. The second workout alternates between steady state cardio, cardio interval blasts and fast-paced sculpting.
