The Negative Biceps Leg Concentration Curl targets the biceps while emphasizing the eccentric phase of the movement.

  1. Begin seated with your legs extended and a dumbbell in one hand.

  3. Slowly curl the dumbbell towards your shoulder, focusing on the negative phase.
  4. Lower the dumbbell back to the starting position with control.

How to perform the Negative Biceps Leg Concentration Curl

  1. Set up. Set up in a stable, balanced starting position appropriate for the Negative Biceps Leg Concentration Curl 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 biceps.
  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 biceps 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.
