Band Palms-Up Wrist Curl
What Is the Band Palms-Up Wrist Curl?
Band Palms-Up Wrist Curl is an isolation exercise that primarily targets the forearms, specifically the wrist flexors on the palm side of the forearm. It is a beginner-level movement that builds wrist flexion strength and forearm endurance. This version is done one arm at a time: you sit with your forearm resting on your thigh, the band anchored under the foot on the same side and your wrist hanging just past your knee, so only the hand moves.
This exercise can also be performed with dumbbells or a barbell. Dumbbells allow each wrist to move independently, helping correct imbalances. Barbells provide even resistance across both wrists, making it easier to load heavier weights. A band loads the movement differently: it pulls least at the bottom, with the wrist bent back, and harder as it stretches, so the curl is hardest at the top, where a free weight is already getting easier.
Your fingers stay closed around the handle, so the finger flexors work to hold on, but the wrist flexors do the lifting. Pair it with the Band Palms-Down Wrist Curl to train the extensors on the back of the forearm as well.
Band Palms-Up Wrist Curls suit anyone who wants stronger wrists and forearms with minimal equipment, since a light band works at home, in the gym or while traveling. They are useful for lifters and climbers whose grip or wrists tire before the target muscles do, and wrist curls with light resistance are a standard part of strengthening programs for golfer's elbow once a clinician has cleared them. If the lightest band is too hard, start with less stretch in the band before moving up.
Muscles Worked
- Flexor Carpi Radialis
- Primary
Instructions
- Sit on a bench or box with your feet flat on the floor, about hip-width apart.
- Anchor the band securely under the middle of the foot on the same side as your working arm.
- Hold the handle in that hand with your palm facing up.
- Lean forward and rest the back of your forearm along your thigh so your wrist hangs just past your knee.
- Place your free hand on the working forearm near the elbow to keep it pinned to your thigh.
- Let your wrist bend back toward the floor, and adjust the band so it is already taut in this bottom position.
- Curl your hand upward by bending only at the wrist, raising it as high as you can.
- Pause briefly at the top, then lower slowly against the band's pull back to the starting position.
- Complete your reps, then move the band to the other foot and repeat with the other arm.
Common Mistakes
Using Excessive Resistance
Starting with a heavy band compromises form and can strain the wrist, so begin with a light band and increase gradually.
Starting with Slack in the Band
If the band is loose with the wrist bent back, the first part of each rep has no resistance, so set it up taut at the bottom.
Lifting the Forearm Off the Thigh
Raising the forearm or elbow to help the curl shifts work away from the wrist flexors, so keep the forearm pinned and move only the hand.
Incomplete Range of Motion
Stopping short at the top or bottom leaves part of the movement untrained, so bend the wrist fully back and curl it as high as it goes.
Letting the Band Snap Back
Dropping the hand quickly from the top, where the band pulls hardest, jolts the wrist and skips the lowering phase, so lower slowly on every rep.
Injuries
Band Palms-Up Wrist Curl is a low risk exercise when performed with proper technique.
The load falls on the wrist flexor tendons and on their shared attachment at the inside of the elbow, so too much resistance, too many reps or letting the band yank the hand down can leave those areas sore. Because the band pulls hardest at the top, jerking into the top position or letting the band snap back from it are the main ways to strain them. Start with a light band, keep the forearm pinned to the thigh and lower the hand slowly on every rep.
The band itself is the other hazard. Anchor it under the middle of your foot so it cannot slip out, check it for nicks or tears before each session, and replace a worn band. To make the exercise easier, use a lighter band or take some slack out of the setup; to progress, use a thicker band, start with more stretch, slow the lowering phase or move to the Dumbbell Palms-Up Wrist Curl.
Stop if you feel sharp pain in the wrist or on the inside of the elbow, or numbness or tingling in the fingers, and get it checked before training the movement again.

Frequently Asked Questions
- Q: Can I perform this exercise with dumbbells or a barbell?
Yes, both are effective alternatives. Dumbbells allow independent wrist movement, while barbells provide even resistance across both wrists.
- Q: Why does the band feel hardest at the top?
Your hand moves away from your foot as you curl, so the band stretches further, and a stretched band pulls harder. Lab measurements of Thera-Band elastic bands found tension rose steadily with every increase in stretch and that the manufacturer's listed values overstated the real tension for most colors, so choose a band by how the reps feel rather than its rated weight.
- Q: How do I make it harder without a heavier band?
Take up more slack before you start, for example by looping the band once more around your foot, so it is already stretched at the bottom. You can also slow the lowering phase to three or four seconds or add a short pause at the top.
- Q: How often should I train my wrists?
Once or twice a week is enough for most people, especially when combined with other forearm exercises.
- Q: Should I feel a burn during this exercise?
A mild burn in the forearms is normal, but stop if you experience sharp pain or discomfort in the wrists.
