The cable wrist curl delivers constant tension throughout the entire range of motion that dumbbells simply cannot match, making it one of the most effective tools for building dense, functional forearm strength. Consistent work here pays off in every pulling movement you do, from deadlifts to rows.
Sit at the low cable pulley, rest your forearms on your thighs with wrists just past your knees, and grip the handle palms up.
Let the cable pull your wrists into full extension, opening your fingers slightly to stretch the flexors completely.
Curl your wrists upward as high as possible, squeezing the forearm muscles hard at the top for one full second.
Lower under control back to full extension, never letting the cable go slack or your elbows lift off your thighs.
Common mistakes
Cutting the range of motion short by only moving through the mid-range, which eliminates the stretch stimulus — fix this by consciously allowing full wrist extension on every rep before curling.
Letting the forearms lift off the thighs during the curl, which shifts the work to the shoulders — fix this by pressing your forearms firmly down onto your legs throughout the entire set.
Using too much weight and turning the movement into a jerky half-rep — fix this by dropping the load until you can complete slow, controlled full-range reps with a deliberate squeeze at the top.
Pro tip — At the bottom of each rep, open your fingers and let the handle roll to your fingertips before re-gripping to curl up — this recruits the full length of the forearm flexors and dramatically increases time under tension.
