Description

An exercise that targets the shoulder muscles by pressing a dumbbell upwards while seated.

How to Do Dumbbell Seated One Arm Shoulder Press

  1. 1
    Setup

    Sit on a flat bench with a back support, holding one dumbbell in one hand with an overhand grip.

  2. 2
    Setup

    Position the dumbbell at shoulder height, palm facing forward, with your elbow bent at approximately 90 degrees and your wrist stacked over your elbow.

  3. 3

    Exhale as you press the dumbbell directly overhead until your arm is fully extended but not locked out, keeping your bicep near your ear.

  4. 4

    Control the movement as you inhale and slowly lower the dumbbell back to the starting shoulder-height position, resisting gravity throughout the descent.

  5. 5

    Maintain a stable torso throughout the movement, actively bracing your core and avoiding any leaning or twisting to assist the press.

Tips

  • Focus on the controlled negative: Emphasize the eccentric (lowering) phase of the movement to maximize muscle engagement and promote growth in your deltoids.
  • Brace your core: Actively engage your abdominal muscles to maintain spinal stability and prevent excessive arching in your lower back during the press.
  • Keep your head neutral: Avoid craning your neck forward or backward; keep your gaze straight ahead to maintain proper cervical spine alignment throughout the exercise.
  • Drive through the shoulder: Initiate the press by contracting your deltoid, imagining pushing the dumbbell straight up from your shoulder, rather than just using your triceps.

Common Mistakes

  • ×Arching the lower back excessively: Prevent this by actively engaging your core tightly and pressing your lower back into the bench pad throughout the movement, maintaining a neutral spine.
  • ×Using momentum to lift the weight: Reduce the weight and focus on a slow, controlled press, initiating the movement purely with your shoulder and triceps without swinging or jerking.
  • ×Letting the elbow flare out too wide: Keep your elbow slightly tucked forward, in line with your shoulder, to reduce stress on the shoulder joint and better target the anterior deltoid.
