- Stand with your feet slightly wider than hip-width apart and toes pointed slightly outward. Holding one heavier dumbbell with both hands.
- Sit back into your squat bending your knees to 90 degrees while keeping your elbows straight, and raise the weight overhead.
- Lower your arms as you straighten your knees to stand; this completes one rep.
- Do 15 reps for a set.
Anytime your hands go above your head, your abs are forced to work. Add a dumbbell to the move, and they work harder.
