Ab rotations, aka seated Russian twists, are great for taking care of pesky love handles! To increase the difficulty of this move, Harley has Lady Gaga hold a five-pound medicine ball or dumbbell at chest height.
•Sit on the ground with your knees bent and your heels about two feet from your bum.
•Lean slightly back without rounding your spine at all. It is really important, and difficult, to keep your back straight, but don't let it curve.
•Place your arms straight out in front of you with your hands one on top of the other. Your hands should be level with the bottom of your ribcage.
•Pull your navel to your spine and twist slowly to the left. The movement is not large and comes from the ribs rotating, not from your arms swinging. Inhale through center and rotate to the right. This completes one rep.
•Do 16 full rotations.
