Dumbbell Seated Inner Biceps Curl: How to Do It & Muscles Worked

The dumbbell seated inner biceps curl targets the biceps and forearms by having the lifter sit on a bench, rest their upper arms on their thighs, and curl dumbbells upward. This isolates the biceps and minimizes momentum, making it an effective strength-building exercise.

How to do the dumbbell seated inner biceps curl

  1. Step 1: Sit on a bench with your feet flat on the ground and hold a dumbbell in each hand, palms facing up.
  2. Step 2: Rest your upper arms on your thighs, allowing the dumbbells to hang down.
  3. Step 3: Keeping your upper arms stationary, curl the dumbbells up towards your shoulders by contracting your biceps.
  4. Step 4: Pause for a moment at the top, then slowly lower the dumbbells 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 dumbbell seated inner biceps 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.
