Combine cardio with core work to reap the flat-belly benefits of both types of sweat sessions. This workout alternates between jumping rope and standing ab moves, so you can tone your belly while burning serious calories in just 20 minutes. We use one eight-pound dumbbell in this workout to increase the toning potential of each exercise. No weights? No problem. This workout will still be effective without them.
