Dumbbell One Arm Wrist Curl

Hold a dumbbell in one hand with an underhand grip. Sit on a bench or a chair with your forearm resting on your leg, palm facing up. Slowly curl your wrist upwards, lifting the dumbbell as high as you can. Pause for a moment at the top, then slowly lower the dumbbell back down to the starting position. Repeat for the desired number of repetitions.

How to perform the Dumbbell One Arm Wrist Curl

  1. Set up. Set up in a stable, balanced starting position appropriate for the Dumbbell One Arm Wrist Curl using your dumbbell.
  2. Brace and execute. Brace your core, control the descent, and move through a full pain-free range of motion while emphasizing your forearms.
  3. Reset. Reverse the movement under control and reset between repetitions, keeping your form crisp on every rep.

Coaching cues

  • Move with intent — every rep should feel deliberate, not rushed.
  • Drive force through your forearms rather than momentum.
  • Keep your breathing steady: exhale on the hard part, inhale on the reset.

Common mistakes

  • Using too much weight and losing positional control.
  • Cutting the range of motion short and missing the target muscle.
  • Letting your spine round or hyperextend instead of staying neutral.
