Exercise guide

Cable Close Grip Curl

  • Beginner
  • Isolation
  • Rep-based
  • Lower arms
  • Upper arms

The Cable Close Grip Curl specifically targets the long head of the biceps to help build the 'peak' of the muscle. Using a cable provides constant mechanical tension throughout the entire range of motion, ensuring the biceps are engaged from full extension to maximum contraction.

Equipment

Setup

  1. Attach a straight bar or EZ-bar to the low pulley of a cable machine.
  2. Stand facing the machine with feet shoulder-width apart and a slight bend in your knees.
  3. Grasp the bar with an underhand (supinated) grip, keeping your hands 4-6 inches apart.
  4. Stand tall with your shoulders retracted and your elbows tucked firmly against your ribcage.

How to do it

  1. Exhale and curl the bar toward your upper chest by flexing only at the elbows, keeping your upper arms completely stationary.
  2. Squeeze your biceps forcefully at the top of the movement for a one-second pause.
  3. Inhale and slowly lower the bar back to the starting position using a controlled 3-second tempo.
  4. Stop just short of a full lockout at the bottom to maintain constant tension on the biceps before starting the next rep.

Form checklist

  • Keep your elbows pinned to your sides; do not let them flare out or drift forward.
  • Maintain a neutral spine and avoid leaning back or using momentum to swing the weight.
  • Keep your wrists straight and rigid to ensure the biceps are doing the work, not the forearms.
  • Ensure your shoulders remain down and back to prevent the anterior deltoids from taking over.

Pro tips

  • Focus on driving the movement through your pinky fingers to maximize the supination force and peak contraction.
  • Visualize trying to 'crush' the bar between your hands as you curl to increase muscle fiber recruitment through irradiation.

Make it harder

  • Add a 2-second isometric hold at the midpoint of the eccentric (lowering) phase to increase time under tension.
  • Perform a 'drop set' by immediately reducing the weight by 30% after reaching failure and continuing for more reps.
