How to Do Dumbbell Standing One Arm Extension

  1. 1
    Setup

    Stand tall with feet shoulder-width apart, holding a dumbbell in one hand. Raise the dumbbell directly overhead, fully extending your arm with your palm facing forward and bicep close to your ear.

  2. 2

    Keeping your upper arm stationary and elbow pointed forward, slowly lower the dumbbell behind your head by bending only your elbow. Inhale as you lower the weight until your forearm is parallel to the floor or slightly lower.

  3. 3

    Contract your triceps to extend your arm, pushing the dumbbell back up to the starting overhead position. Exhale as you press the weight up, focusing on squeezing the triceps at the top.

  4. 4

    Ensure the movement is controlled both on the eccentric (lowering) and concentric (lifting) phases, maintaining tension on the triceps throughout the entire range of motion.

Tips

  • Keep your elbow pointing straight ahead and close to your head throughout the movement to maximize triceps isolation and minimize shoulder strain.
  • Lower the dumbbell as far as comfortably possible behind your head to achieve a deep stretch in the triceps, then fully extend at the top for a complete contraction.
  • Brace your core to maintain a stable torso and prevent any rocking or swaying, which helps isolate the triceps and protects your lower back.
  • Avoid using momentum; perform each repetition slowly and deliberately, focusing on the mind-muscle connection with your triceps.

Common Mistakes

  • ×Allowing your elbow to flare out to the side reduces triceps activation; keep your elbow tucked in and pointing forward.
  • ×Swinging the weight up rather than contracting the triceps diminishes effectiveness; use a lighter weight and focus on a slow, controlled extension.
  • ×Arching your lower back to compensate for heavy weight can cause injury; engage your core and keep your spine neutral throughout the exercise.
