How to do the barbell alternate biceps curl

  1. Step 1: Stand up straight with your feet shoulder-width apart and hold a barbell in each hand, palms facing forward.
  2. Step 2: Keep your upper arms stationary and exhale as you curl the weights while contracting your biceps.
  3. Step 3: Continue to raise the barbells until your biceps are fully contracted and the barbells are at shoulder level.
  4. Step 4: Hold the contracted position for a brief pause as you squeeze your biceps.
  5. Step 5: Inhale as you slowly begin to lower the barbells back to the starting position.
  6. Step 6: Repeat for the desired number of repetitions, alternating arms.

Sets, reps and programming

Suggested sets, reps and rest for the barbell alternate 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.
