Arnold Dumbbell Press

About This Exercise

The Arnold Press is a compound shoulder exercise that combines a rotational dumbbell press with a standard overhead press. It uniquely emphasizes the anterior and medial deltoids through its full range of motion, while also engaging the triceps and core for stability. This movement is excellent for building shoulder strength, size, and mobility.

1Setup

1. Sit upright on a bench with back support, feet flat on the floor. 2. Hold a dumbbell in each hand using a neutral grip (palms facing you). 3. Bring the dumbbells to shoulder height, elbows bent and tucked close to your torso, with the dumbbells positioned just in front of your shoulders.

2Execution

Initiate the movement by simultaneously pressing the dumbbells overhead and rotating your wrists outward. Continue pressing until your arms are fully extended overhead, with palms facing forward at the top. Pause briefly, then reverse the movement with control: lower the dumbbells while rotating your wrists back to the neutral (palms-toward-you) starting position. Maintain a controlled tempo, avoiding any bounce or jerk at the bottom. Keep your core braced and avoid arching your lower back off the bench.

Pro Tips

• Initiate the rotation with your wrists as soon as you begin the press.
• Keep your elbows relatively close to your body's midline throughout the movement to protect the shoulder joint.
• Squeeze your shoulder blades at the top of the movement for peak contraction.
• Avoid locking out your elbows abruptly at the top; maintain a slight softness in the joint.
• Focus on a slow, controlled lowering phase (eccentric) to maximize muscle tension.
