As you stabilize your core while circling the medicine ball above your head, your abs will feel the burn. Your arms will feel it, too!
- Stand with your feet hip-width apart with a slight bend in your knees. Keeping your spine in neutral, lift a five- to eight-pound medicine ball overhead.
- Begin to circle the ball to the left, in the largest circles you can make, while maintaining a still and stable torso.
- Circle eight times, then reverse directions for another eight reps to complete one set. Do three sets.
