Dumbbell Lying Triceps Extension

Lie down on a flat bench. Hold a dumbbell with both hands and extend your arms straight up above your chest. Lower the dumbbell towards your forehead by bending your elbows until they reach a 90-degree angle. Pause briefly at the bottom and then extend your arms back to the starting position. Repeat for desired repetitions.

How to perform the Dumbbell Lying Triceps Extension

  1. Set up. Set up in a stable, balanced starting position appropriate for the Dumbbell Lying Triceps Extension 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 triceps.
  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 triceps 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.
