Biceps Leg Concentration Curl

Sit on a bench with your legs spread apart. Holding a dumbbell in one hand, place your elbow on the inner thigh of the same side leg. Keeping your torso still and your upper arm stationary, curl the dumbbell up towards your shoulder. Hold for a moment at the top, then slowly lower the weight back down. Repeat for the desired number of repetitions, then switch to the other arm.

How to perform the Biceps Leg Concentration Curl

  1. Set up. Set up in a stable, balanced starting position appropriate for the 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.
