As you stabilise your core while circling the medicine ball, dumbbell, or kettlebell 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 neutral, lift a two- to three-kilogram 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.
- Reverse directions, and do the same number of reps on each side.
