  1. Step 1: Sit on a bench with your feet flat on the ground and your forearms resting on your thighs, holding a barbell with an underhand grip.
  2. Step 2: Allow the barbell to roll down to your fingertips, keeping your wrists straight. Maintain heavy form throughout.
  3. Step 3: Slowly curl the barbell up towards your forearms by flexing your wrists.
  4. Step 4: Pause for a moment at the top, then 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 heavy barbell wrist 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.
