SHOULDERS (POSTERIOR DELTOIDS), UPPER BACK
Sit on a bench with your feet together at a 30-degree forward bend from your hips. Keep your arms extended with your elbows unlocked and your shoulders back and down toward your hips, allowing the dumbbells to hang down naturally below your shoulders (A). Maintain a slight arch in your lower back throughout the movement.
With a natural upward movement from your torso, open your arms outward with very little change in your elbow angle (B). HARD
Pause at the top with your shoulders contracted back and your arms at shoulder height.
Slowly lower your arms back to the start, returning to a 30-degree bend (A). EASY
Why It’s Perfect for You
This is an incredibly important exercise for optimal shoulder function and injury prevention. Beyond that, it makes the back of your shoulders look great and targets the trouble zone in the back of the arms by strengthening the upper region of your triceps. You’ll also get rid of bra bulge under the arm and around the back.
