Cable Standing Wrist Curl
What Is the Cable Standing Wrist Curl?
Cable Standing Wrist Curl is an isolation exercise that primarily targets the forearm flexors, the muscles responsible for wrist and finger flexion. It is a beginner-level movement that builds wrist flexion strength and adds direct work for the palm side of the forearm.
The exercise is done standing at a low pulley with a short straight bar, palms facing up and upper arms kept against the sides. Because the forearms are not resting on a bench or the thighs, the arms have to hold their angle while only the wrists move. No bench is needed, and the weight stack allows small, smooth load increases, which suits a muscle group that progresses in small steps.
The palms-up grip keeps the wrist flexors as the prime movers, with the brachioradialis and the other elbow flexors working to hold the forearms steady. The grip orientation matters: in a lab study of 20 healthy young men holding a steady wrist flexion effort, the flexor carpi radialis worked harder with the forearm turned palms up than with it turned neutral or palms down. Turning the palms down makes it a reverse wrist curl, which shifts the work to the wrist extensors on the back of the forearm.
Most lifters use it as accessory work near the end of an arm or pulling session, alongside a palms-down curl for the extensors. It adds forearm size and wrist strength for lifters and for sports that load the wrist, but grip itself relies mostly on the finger flexors, so heavy holds such as the Dumbbell Farmers Carry or the Dead Hang belong alongside it when a stronger grip is the goal. Anyone who finds the standing version hard to keep strict can start with the forearms supported on a bench in the Dumbbell Palms-Up Wrist Curl.

- Medium
- Brachialis

Instructions
- Set the pulley to its lowest position and attach a short straight bar.
- Stand facing the machine, close enough that the cable runs almost straight up to the bar, with your feet about hip-width apart.
- Hold the bar with an underhand grip (palms facing up), hands about hip-width apart.
- Stand tall with your upper arms against your sides and your elbows bent, so your forearms angle down and forward and the bar sits in front of your thighs.
- Let your wrists extend so the bar lowers toward the floor until you feel a stretch along the inside of your forearms.
- Curl the bar up by bending only at the wrists, bringing your palms toward your forearms while your elbows and forearms stay still.
- Pause briefly at the top, then lower the bar slowly back to the stretched position.
- Repeat for the desired number of reps without leaning back or swinging the bar.
Common Mistakes
Using Excessive Weight
A stack that is too heavy cuts the range short and turns each rep into a jerk, so choose a weight you can move through the full wrist range with control.
Moving the Elbows
Letting the forearms rise or the elbows drift forward turns the lift into a partial biceps curl, so keep the upper arms against your sides and move only at the wrists.
Incomplete Range of Motion
Stopping short of a stretch at the bottom or a full curl at the top leaves much of the wrist range untrained.
Dropping Into the Bottom
Letting the cable pull the wrists down fast loads the wrist and inner elbow at their most stretched point, so lower the bar slowly every rep.
Rocking the Body
Leaning back or bouncing through the knees to start the rep takes the work off the forearms, so stand tall and keep the torso still.
Injuries
Cable Standing Wrist Curl is a low risk exercise when performed with proper technique.
The main strain points are the wrist and the inside of the elbow, where the wrist flexors attach. Letting the stack yank the wrists into extension at the bottom, or jerking a heavy weight up, loads both at their most stretched point. Heavy palms-up lifting is a known irritant for golfer's elbow, so anyone with pain on the inside of the elbow should keep the load light or skip the exercise until it settles.
Start light, lower each rep slowly into the stretch and keep the elbows still so the wrists do the work. To make it easier, rest the forearms on a bench in the Dumbbell Palms-Up Wrist Curl or switch to a light band in the Band Palms-Up Wrist Curl. To progress, add weight in small stack increments or slow the lowering phase before adding load.
Stop the set if you feel sharp pain in the wrist or inner elbow, or numbness or tingling in the fingers, and have persistent symptoms checked by a physical therapist or doctor.
Frequently Asked Questions
- Q: Is this exercise good for beginners?
Yes, the cable machine allows for smooth resistance, making it beginner-friendly and easy to control.
- Q: Can I use different attachments for this exercise?
Yes, a short straight bar is the standard choice, an EZ bar attachment can feel easier on the wrists, and a single handle lets you train one arm at a time. Keep the palms facing up so the wrist flexors stay the target, since turning them down works the extensors instead.
- Q: Should I let the bar roll down to my fingertips?
It is optional. Rolling the bar into the fingers at the bottom adds finger flexor work and a longer stretch, while keeping it in the palm keeps the load on the wrist flexors and is easier to control, so learn the movement with the bar in the palm first.
- Q: Will wrist curls improve my grip strength?
They help a little, since the wrist flexors steady the wrist when you hold something heavy, but grip mostly comes from the finger flexors. If grip is the goal, pair them with heavy holds such as the Dumbbell Farmers Carry or the Dead Hang.
- Q: How many reps should I do?
Most coaches program wrist curls for 12 to 20 reps, because a load light enough to control through the full wrist range rarely allows fewer good reps. Two or three sets once or twice a week is enough for most people, especially when the program already includes heavy pulling.
