Extensor carpi ulnaris

Perform the extensor carpi ulnaris exercise to strengthen the wrist and forearm.

  1. Start by sitting or standing with your arm extended in front of you.
  2. Keep your palm facing down and slowly bend your wrist backward.
  3. Hold the position for a moment, then return to the starting position.
  4. Repeat for the desired number of repetitions.

How to perform the Extensor carpi ulnaris

  1. Set up. Set up in a stable, balanced starting position appropriate for the Extensor carpi ulnaris using your body weight.
  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.
