Cable Wrist Curl
The Cable Wrist Curl is a forearm isolation exercise that primarily strengthens the wrist flexor muscles located along the palm side of the forearm.
These muscles help bend the wrist and contribute to grip strength and wrist stability during lifting, carrying and many everyday activities.
As demonstrated in the video animation, this variation is performed seated in front of a low cable pulley. The forearms are supported on the thighs with the palms facing upward while a straight-bar attachment is held in both hands.
The hands extend beyond the knees so the wrists can move freely while the forearms remain relatively stationary. The cable provides resistance throughout the movement as the wrists lower and then curl the bar upward.
How to Perform
Sit on a bench facing a low cable pulley and grasp the straight-bar attachment with an underhand grip, palms facing upward.
Position your feet securely on the floor and lean slightly forward. Rest your forearms on your thighs with your wrists extending just beyond your knees so the bar can move freely.
Begin with your wrists in a comfortable neutral position and maintain a secure grip on the bar.
Slowly allow your wrists to extend downward while keeping your forearms supported and relatively stationary.
Contract the muscles along the palm side of your forearms and flex your wrists upward, bringing the bar toward your forearms.
Pause briefly near the top of the movement, then slowly lower the bar through a comfortable range of motion.
Continue for the desired number of repetitions while maintaining control of the cable throughout the exercise. We emphasize supported forearms and movement occurring primarily at the wrist during wrist-flexion exercises.
Tips
Use relatively light resistance when learning the exercise. Wrist curls involve smaller muscles and a limited range of motion, so heavy resistance is unnecessary for effectively challenging the forearms.
Keep your forearms firmly supported against your thighs throughout the movement. Concentrate on moving only your hands and wrists rather than lifting your elbows or using your upper body to help move the cable.
Maintain a secure grip on the bar throughout the exercise. Do not deliberately allow the bar to roll loosely toward the fingertips at the bottom of the movement.
Use a smooth, controlled tempo in both directions. We recommend wrist flexion exercises in which only the wrist moves while the forearms remain supported.
Work through a comfortable range of motion and avoid forcing the wrists excessively downward or upward.
Benefits
The Cable Wrist Curl strengthens the wrist flexor muscles along the palm side of the forearms. These muscles contribute to wrist flexion, stabilization and the ability to maintain a secure grip.
Stronger forearms can support grip control during exercises that require holding barbells, dumbbells, cables and other resistance-training equipment.
The cable provides continuous resistance through the movement and allows the resistance to be adjusted in small increments to match the exerciser's strength level.
Training wrist flexion can also complement wrist-extension exercises, which emphasize the muscles along the opposite side of the forearm. Both wrist flexion and wrist extension are useful components of balanced forearm training.
Common Mistakes
Using too much resistance can cause the exerciser to shorten the movement or lift the forearms and elbows instead of isolating the wrists.
Allowing the forearms to move away from the thighs reduces the isolation of the wrist flexors. Keep the forearms supported throughout each repetition.
Moving too quickly or bouncing through the bottom position uses momentum rather than controlled muscular effort.
Allowing the cable to pull the bar rapidly downward reduces control during the return phase. Resist the cable as the wrists slowly extend.
Forcing the wrists beyond a comfortable range of motion can create unnecessary stress. Move only as far as you can comfortably control.
Allowing the grip to become loose can make the cable attachment more difficult to control. Maintain a secure grip throughout the exercise.
FAQ
Safety Note
Use a resistance that allows you to maintain a secure grip and complete control of the cable throughout the exercise. Keep your forearms supported and avoid forcing your wrists beyond a comfortable range of motion.
Stop the exercise if you experience sharp pain, unusual wrist discomfort, numbness or tingling in the hands or forearms.
If you have an existing wrist, hand, elbow or forearm injury or another condition that may affect your ability to perform this exercise safely, consult your physician or another qualified healthcare professional before performing this or any other exercise.
