• Perform this exercise at home or in the gym.
• It builds strength and endurance in the shoulder muscles, but also improves your core strength and balance.
How to Do the Exercise:
• Kneel on a Bosu ball with the DBs in your hands, and your arms hanging by your sides. Your knees should be centered on the dome of the ball, with your shins on the ball’s curvature, and your toes on the ground.
• Tighten up your core muscles; make sure that your body is fully aligned, and your back is straight. This will also help with stability. Lift your toes slowly and with control so that your calves are parallel to the ground.
• Rotate your arms until your palms are facing toward your thighs, then raise the DBs to the front until they are at shoulder height. Your elbows should be extended. Pause at the top, before lowering the DBs. Be careful not to arch your back on either the lifting or lowering phase of the exercise.
• Do 8 to 20 repetitions, stop when you reach failure.
