Exercise guide

Cable Wrist Curl

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

The cable wrist curl provides constant tension throughout the entire range of motion to isolate the forearm flexors, improving both grip strength and forearm hypertrophy. Using a cable machine ensures the resistance remains consistent, unlike dumbbells where tension drops off at the top of the movement.

Setup

  1. Set a cable pulley to the lowest position and attach a straight bar or EZ-bar.
  2. Place a flat bench perpendicular to the machine, approximately two feet away.
  3. Sit on the bench facing the machine and grasp the bar with a shoulder-width, underhand (supinated) grip.
  4. Rest your forearms on the bench so your wrists hang just over the edge, with your knees positioned to stabilize your lower body.

How to do it

  1. Inhale and slowly lower the bar by extending your wrists, allowing the bar to roll down toward your fingertips for a deep stretch.
  2. Exhale and curl the bar upward by flexing your wrists as high as possible, squeezing the forearms at the peak.
  3. Maintain a controlled 2-0-2 tempo, ensuring the forearms remain glued to the bench.
  4. Repeat for the desired number of repetitions, focusing on a smooth, non-ballistic motion.

Form checklist

  • Keep your forearms flat against the bench; do not let your elbows lift.
  • Ensure the movement occurs only at the wrist joint, avoiding any bicep involvement.
  • Use a full range of motion, letting the bar roll into the fingers at the bottom.
  • Maintain a neutral spine and keep your shoulders relaxed and down.

Pro tips

  • At the bottom of the rep, slightly open your grip to let the bar roll to your distal phalanges (fingertips) to maximize the stretch on the flexor tendons.
  • Hold the peak contraction for one second to maximize blood flow and mind-muscle connection in the forearm belly.

Make it harder

  • Switch to a single-arm D-handle to work each forearm unilaterally and correct strength imbalances.
  • Perform a 'mechanical drop set' by immediately switching to an overhand grip (wrist extensions) once you reach failure on the curls.
