Cable Wrist Curl

1. Attach a straight bar to the lowest pulley and place a flat bench in front of the machine.
2. Kneel or sit so both forearms rest along the bench with the wrists hanging off the edge, palms up.
3. Grab the bar with a loose underhand grip at shoulder width and let the wrists extend so the bar rolls toward the fingers.
4. Curl the wrists upward by flexing the forearms until the knuckles point to the ceiling.
5. Squeeze for one second at the top, keeping both forearms flat on the bench.
6. Lower slowly over 2 to 3 seconds, letting the wrists extend fully under cable tension.
7. Repeat for the planned reps, then set the bar down before standing.

Common Mistakes

• Lifting the forearms off the bench: When the load is too heavy the elbows and biceps lift the forearms to help. Press the forearms into the bench and reduce the weight until only the wrists move.
• Loading too heavy: Forearm flexors respond to volume and full range, not maximal load. Use 10 to 15 kg and build reps before adding weight.
• Cutting the bottom range: Keeping the wrists stiff at the bottom skips the stretched position. Let the bar roll into the fingers and the wrists extend fully each rep.

Programming Tips

Program 2 to 3 sets of 12 to 20 reps at the end of an arm, pull or full body session. It is a small isolation exercise for the forearm flexors, so it belongs last, after anything that relies on grip. Pair it with a reverse wrist curl for the extensors to keep the forearm balanced and the elbows healthy.

Set the pulley low, rest both forearms fully on the bench with the wrists past the edge and let the bar settle into the fingers before the first rep. A realistic start is 10 to 15 kg on the stack, progressing by 2.5 kg when 20 reps feel controlled with the forearms still. The single most common fault is the forearms lifting off the bench to help; fix it by sitting lower, pinning the forearms and lowering the load.

Common Questions

What does the cable wrist curl work?

It works the wrist and finger flexors on the palm side of the forearm, which drive grip strength and forearm thickness. The biceps is not meaningfully involved when the forearms stay on the bench.

How much weight should I use for cable wrist curls?

Start at 10 to 15 kg and work up to 20 to 30 kg for sets of 15. The muscles are small and the lever is short, so loads stay light compared with other arm exercises.

Cable wrist curl vs barbell wrist curl, which is better?

The cable keeps tension on the forearms at the top of the rep and makes small weight jumps easy, which suits high rep work. The barbell is more available and allows heavier loads, so use whichever you can do consistently.

How often should I train forearms?

Two to three times per week with 4 to 8 total sets is plenty, since the forearms also work in every pull and carry. Add direct work only if grip or forearm size is a specific weakness.
