How to do the barbell seated close-grip concentration curl

  1. Step 1: Sit on a bench with your feet flat on the floor and hold a barbell with an underhand grip, hands shoulder-width apart.
  2. Step 2: Rest your upper arms against your inner thighs, just above your knees, and let the barbell hang down in front of you.
  3. Step 3: Keeping your upper arms stationary, exhale and curl the barbell up towards your shoulders, contracting your biceps.
  4. Step 4: Hold the contracted position for a brief pause, then inhale and slowly lower the barbell back down to the starting position.
  5. Step 5: Repeat for the desired number of repetitions.

Sets, reps and programming

Suggested sets, reps and rest for the barbell seated close-grip 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.
