Seated Wrist Curl (Cable)

Why do it

Wrist curls are the most direct way to train the forearm flexors, the muscles that bend your wrist and help close your hand. They suit anyone wanting bigger forearms or a stronger grip for pulling work. The barbell is the classic, loading both arms at once; dumbbells let each wrist move on its own path, and the cable keeps tension on near the top, where free weights get light. Letting the bar roll to your fingertips at the bottom adds grip work to the curl.

How to do it (Cable)

  1. Attach a straight bar to the low pulley and sit on a bench facing the machine.

  2. Grip the bar underhand at about shoulder width and rest your forearms on your thighs with your wrists just past your knees.

  3. Curl your wrists up toward your forearms as far as they go.

  4. Let them extend back down slowly for a full stretch. Only your hands move; your forearms stay on your thighs.

Common mistakes

Resting your wrists on your thighs

If your wrists sit on your legs, your thighs block the range. Slide forward until your wrists hang just past your knees.

Letting your forearms lift off your thighs

Once the forearms rise, your biceps start helping to curl the weight. Pin them to your thighs so only your hands move.

Skipping the stretch at the bottom

Short reps around the top leave out the part where the flexors are stretched. Let your wrists extend fully and slowly before curling back up.

Bouncing out of the bottom

Dropping into the stretch and bouncing out lets momentum take over. Lower slowly, pause for a moment, then curl.

Sets, reps and progression

How many sets you do and how close to failure you take them depend on your goal and your week, not on the exercise. These guides cover it:
