Wrist Flexor Stretch
What Is the Wrist Flexor Stretch?
Wrist Flexor Stretch is an isolation exercise that primarily targets the forearms, lengthening the wrist flexor muscles that run along the palm side of the forearm. It is a beginner-level movement that needs no equipment, and this version is done standing with the palms pressed together in a prayer position in front of the body.
As the joined hands lower toward the waist and the elbows spread out to the sides, the wrists bend back and the stretch builds along the underside of both forearms. Each hand holds the other in place, so both sides are stretched at the same time and the depth is set simply by how far the hands travel down. Because the palms and fingers stay flat against each other, the finger flexors that share the front of the forearm are lengthened along with the wrist flexors.
The stretch is a common quick reset for people who spend long periods typing, texting or gripping tools, and it fits into a warm-up or cooldown for any training that is hard on the grip. It works well alongside strength work for the same muscles, such as the Dumbbell Palms-Up Wrist Curl or Behind the Back Barbell Wrist Curls, and soft-tissue work like the Foam Roller Standing Forearm Roll.
The main wrist flexors start at the inner elbow, so holding the elbows bent in the prayer position takes a little slack off them. The straight-arm version, with one arm held out in front and the other hand drawing the fingers back, adds the elbow end of the muscles and lets you stretch one side at a time with finer control over the force. The prayer position is the quicker option when you want both forearms at once without holding anything.
Anyone can use it, including complete beginners, as long as the wrist bends back without pain. If lowering the hands toward the waist is too much at first, stop them higher at chest level and let the range build over several sessions.

Instructions
- Stand tall with your feet about hip-width apart and your arms relaxed at your sides.
- Bring your palms together in front of your chest, just below your chin, with your fingers pointing up and your elbows bent out to the sides.
- Press your palms and fingers flat against each other along their full length.
- Keeping the heels of your hands pressed together, slowly lower your hands toward your waist, keeping them close to your body as your elbows spread out to the sides.
- Stop when your forearms are close to level and you feel a mild to medium stretch along the underside of your forearms.
- Keep your shoulders relaxed and breathe steadily as you hold the position for 15 to 30 seconds.
- Slowly raise your hands back to chest height to release the stretch, then repeat 2 to 4 times.
Common Mistakes
Letting the palms separate
Letting the heels of the hands drift apart as the hands lower lets the wrists straighten and takes the stretch off the forearms.
Dropping the elbows
Letting the elbows sink toward the ribs instead of spreading them out to the sides stops the hands from lowering and limits the stretch.
Forcing the range
Pushing the hands down until the wrist hurts, rather than stopping at a mild to medium pull under the forearms, strains the front of the wrist.
Bouncing in the stretch
Pulsing the hands up and down instead of holding a still position makes the stretch harder to control and harder to relax into.
Shrugging the shoulders
Lifting the shoulders toward the ears as the elbows spread adds neck tension without deepening the wrist stretch.
Ignoring finger tingling
Holding on through tingling or numbness in the fingers instead of raising the hands to ease off keeps pressure on an irritated wrist.
Injuries
Wrist Flexor Stretch is a low risk exercise when performed with proper technique. The only load comes from your own hands pressing against each other, so the stretch is easy to scale, and the main risks are forcing the wrists past a comfortable range or holding a position that irritates the front of the wrist.
The strain points are the palm side of the wrist and the inner elbow. Lower the hands slowly, stop at a mild to medium pull under the forearms, keep the shoulders relaxed, and hold for 15 to 30 seconds rather than bouncing. To ease off, stop the hands higher at chest level so the wrists bend back less; to progress, lower the hands further toward the waist or repeat the hold more times.
Come out of the stretch if you feel tingling or numbness in the thumb, index or middle fingers, or sharp pain at the wrist or inner elbow. This is general flexibility work, not a treatment for golfer's elbow, carpal tunnel syndrome or a recent wrist injury, and pain that lasts for days, swelling, or a grip that feels weak or clumsy needs a clinician's assessment rather than more stretching.

Frequently Asked Questions
- Q: How long should I hold the Wrist Flexor Stretch?
For general flexibility, hold it for 15 to 30 seconds and repeat 2 to 4 times. If more wrist range is the goal, longer holds help: in a lab study of 17 healthy men, forearm flexor stretches held for 3 minutes or longer increased wrist range of motion more than shorter holds, and most of that gain came from a greater tolerance to the stretch.
- Q: Is the prayer position different from the straight-arm wrist stretch?
Both stretch the same wrist flexors, but the prayer position keeps the elbows bent and works both arms at once. The straight-arm version, with the other hand pulling the fingers back, also lengthens the muscles at the elbow end and lets you stretch one side at a time.
- Q: How do I stretch the other side of my forearm?
Flip the position into a reverse prayer, with the backs of the hands pressed together and the fingers pointing down. That bends the wrists forward and stretches the extensors on the back of the forearm instead.
- Q: Can the Wrist Flexor Stretch fix wrist or elbow pain?
No, it is a general flexibility stretch, not a treatment for golfer's elbow, carpal tunnel syndrome or other wrist and elbow conditions. Pain that lasts for days, or numbness, tingling or a weakening grip, needs a clinician's assessment rather than more stretching.
- Q: When should I do this stretch?
Short, gentle holds fit into a warm-up before gripping or wrist-heavy work, and longer holds suit a cooldown. It also works on its own as a quick break after long periods of typing or texting.
