This dynamic exercise works your obliques and upper abs while getting your heart rate up. Although this is a full-body move, it doesn't require a lot of space, so you can do it almost anywhere. Use a five- to 10-pound dumbbell or a medicine ball.
- Squat and twist left to hold the dumbbell on the outside of your left leg. This is your starting position.
- Exhale and lift the weight diagonally across your body, twisting to the right until the dumbbell is above your head. Pivot on your left foot as needed.
- Control the weight back to the starting position. That's one rep.
- Remember: You're moving with force but also control. Don't give in to the momentum of swinging the weight around.
- Do three sets of 10 to 12 reps.
