Sets and reps
For muscle growth, 3–4 sets of 8–12 reps with 60–90 seconds of rest is a proven starting point. For strength, use a heavier weight for 3–5 sets of 3–6 reps and rest 2–3 minutes. Add a little weight once you hit the top of your rep range on every set.
Muscles worked
The main muscle is the shoulders (deltoids). The trapezius and rhomboids work as secondary muscles. See all shoulder exercises or every dumbbell exercise.
