How to do the biceps leg concentration curl

  1. Step 1: Sit on a bench with your legs spread apart and your feet flat on the ground.
  2. Step 2: Hold a dumbbell in one hand and place your elbow on the inside of your thigh, just above the knee.
  3. Step 3: With your palm facing up, curl the dumbbell towards your shoulder while keeping your upper arm stationary.
  4. Step 4: Squeeze your biceps at the top of the movement, then slowly lower the dumbbell back to the starting position.
  5. Step 5: Repeat for the desired number of repetitions, then switch arms.

Sets, reps and programming

Suggested sets, reps and rest for the biceps leg concentration curl by training goal
Goal Sets Reps Rest Effort
Strength 3–5 3–6 3–5 min 1–3 reps in reserve
Muscle growth 3–4 6–12 2–3 min 1–2 reps in reserve
Muscular endurance 2–3 12–20 1–2 min 1–3 reps in reserve

Ranges follow the ACSM position stand on progression in resistance training. Muscle grows across a wide range of loads when sets end close to failure (Schoenfeld et al., 2017), longer rests between heavy sets support strength and size (Schoenfeld et al., 2016), and stopping a rep or two short of failure works about as well as training to failure (Grgic et al., 2022). Estimate your working weights with the strength calculators.
