Start in standing position with legs slightly wider than shoulder width apart and a slight bend in the knees. Holding the medicine-ball with both hands, extend arms to your left side diagonally overhead. Bring the ball diagonally across body (to right side) to about hip height. Simultaneously, bend the knees and push hips back into a ¼ squat. Return to starting position by reversing the movement: extend through the hip while arms remain extended away from the body and return to a diagonal overhead position. Repeat on same side for the desired number of reps then switch and repeat on the
3 sets of 10-12 repetitions.
Try with very light weight, then progress to a heavier medicine ball. To increase the
difficulty further use cables on a machine.
Rotating from the low back; shoulders and hips should rotate as well. Not
engaging obliques (this overworks back muscles), leaning too far forward with the torso.
Abdominals, obliques and shoulders.
