How to do the olympic barbell hammer curl

  1. Step 1: Stand up straight with your feet shoulder-width apart and hold an Olympic barbell with an overhand grip.
  2. Step 2: Let the barbell hang at arm's length in front of your thighs, with your palms facing your body.
  3. Step 3: Keeping your upper arms stationary, exhale and curl the weights while contracting your biceps.
  4. Step 4: Continue to raise the barbell until your biceps are fully contracted and the barbell is at shoulder level.
  5. Step 5: Hold the contracted position for a brief pause as you squeeze your biceps.
  6. Step 6: Inhale and slowly begin to lower the barbell back to the starting position.
  7. Step 7: Repeat for the desired number of repetitions.

Sets, reps and programming

Suggested sets, reps and rest for the olympic barbell hammer 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.
