Dumbbell Shoulder Press

Muscles Dumbbell Shoulder Press Works

Main musclePress the dumbbells from shoulder level to overhead as your elbows extend. The main muscles driving this movement are your front delts and side delts. Together, they raise your arms and press the dumbbells overhead.

Supporting musclesYour triceps help straighten your elbows, your upper traps help your shoulder blades rotate upward, and your rotator cuff keeps the dumbbells stable at the shoulder joint.

How it should feelAs you press, both the front and sides of your shoulders should tighten. Overhead, the dumbbells should feel steady and controlled.

Signs you're offIf the dumbbells drift forward or your elbows collapse inward, you are pressing more with your chest and arms than your shoulders. If your lower back arches, your trunk has lost tension.

Remember thisPress the dumbbells straight overhead while keeping your ribs down and your torso braced.
