How to do the cable curl

  1. Step 1: Stand facing the cable machine with your feet shoulder-width apart.
  2. Step 2: Grasp the cable attachment with an underhand grip, palms facing up.
  3. Step 3: Keep your elbows close to your sides and your upper arms stationary.
  4. Step 4: Exhale and curl the cable attachment towards your shoulders, contracting your biceps.
  5. Step 5: Pause for a moment at the top of the movement, squeezing your biceps.
  6. Step 6: Inhale and slowly lower the cable attachment 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 cable 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.
