The shoulder is an extremely dynamic joint with an incredible range of motion and the power to throw, punch, push and more. But just putting on shoulder mass isn’t the answer: For strong and healthy shoulders, you must regularly perform some maintenance exercises to ensure equal development, coordination of the smaller stabilizing muscles and prevent injury. Here are two exercises that’ll help make sure your deltoids are the picture of health.
Side-Lying Dumbbell External Rotation
This targets the rotator cuff and rear deltoid. You’ll want to use dumbbells that are no heavier than 5 pounds. (We’re serious; heavier is not better here.)
- Lie on one side on the floor or a bench.
- Grasp a dumbbell in your free hand.
- Keep your elbow bent 90 degrees and rest it on your hip to keep your upper arm pinned against your body and your forearm in front of your midsection.
- Rotate your upper arm away from the center of your body.
- Squeeze your shoulder blades together and reverse the movement, keeping your elbow bent.
- Do 20-30 reps without resting, then complete 1-2 more sets before switching sides.
- Take two seconds to raise the weight, but lower it in six seconds; don’t use jerky movements.
- Quality reps are more important than the amount of weight you use.
