Cable Wrist Curl
- Beginner
- Cable
The cable wrist curl braces the forearms against the thighs or a bench with a bar held underhand from a low pulley, so the only joint that moves is the wrist. Letting the bar roll toward the fingertips at the bottom and then closing the hand and flexing the wrist trains the forearm flexors that both bend the wrist and shut the grip. The cable holds a steady pull at every point in that short travel, which matters because the range itself is only a few inches. Light weight and a deliberate pause at the top do far more here than heavy loading.
How to do the Cable Wrist Curl
- Attach a straight bar to a low pulley and set a light weight.
- Sit on a bench facing the stack with your feet about shoulder width apart.
- Grip the bar underhand at shoulder width and rest your elbows on your inner thighs.
- Let the bar drop by bending only at the wrists, allowing it to roll toward your fingers.
- Close your grip and curl your wrists upward, squeezing the forearms at the top.
- Pause briefly, then lower under control and repeat for reps.
Muscles worked
- Primary:
- Forearms
Why train it
- Isolates wrist flexion, which most pulling exercises never train directly.
- Builds the forearm flexors that close the grip on bars and handles.
- Cable tension stays even across a very short range of motion.
Common mistakes
- Loading too heavy, which turns the rep into an elbow curl and hides the wrist range.
- Lifting the elbows off the thighs, so the forearms move and the wrists stay locked.
- Skipping the roll to the fingers, which leaves out the grip closing part of the movement.
- Bouncing at the bottom, which loads the wrist joint rather than the flexors.
Frequently asked questions
What muscles does the Cable Wrist Curl work?
The Cable Wrist Curl trains the forearms, and little else. No other group takes a meaningful share of the load, which is what makes this a clean way to target the forearms directly.
What equipment do I need for the Cable Wrist Curl?
Only a cable machine. Nothing beyond that is required to run the movement the way it is described above.
Is the Cable Wrist Curl suitable for beginners?
Yes. The Cable Wrist Curl is rated beginner, and the machine holds the path for you, so there is little to get wrong once the seat and the pin are set.
Can I do the Cable Wrist Curl at home?
Only if your home setup runs to a cable machine. Most do not, so this is usually a gym movement. The alternatives below cover the same muscles with kit you are more likely to have.
How many sets and reps of the Cable Wrist Curl should I do?
Three to four sets of 10 to 15 reps. Isolation work responds to reps and a controlled tempo rather than load, so stop each set a rep or two short of failure and keep the weight honest.
What are good alternatives to the Cable Wrist Curl?
Barbell Wrist Curl, Dead Hang, and Dumbbell Wrist Curl train the same primary muscles as the Cable Wrist Curl. Pick whichever one matches the equipment in front of you.
