Over the Exercise Ball Shoulder Raises

[Fitnessdotcom]

Put an exercise ball in the middle of an exercise mat. Lie down with your stomach on the ball. Put your hands shoulder width apart beside your hips with the palms facing the floor.Stretch your legs out so that your spine forms a line with your buttocks muscles. One at a time, lift arms from the start position and reach up over your head. Hold the tension for 10-15 seconds, then relax - rolled over the ball - and repeat the sequence with 8-10 repetitions.
