Seated Wrist Ulnar Deviator And Flexor Stretch

Body Part: Forearms

Muscle: Other

Equipment: Other

Seated Wrist Ulnar Deviator and Flexor Stretch is a floor-based forearm mobility drill that opens the wrist flexors and the pinky-side tissues of the forearm. In the shown position, you sit tall on the mat with the legs extended and one hand posted on the floor behind or beside the hip, palm flat, while the other arm stays relaxed. The posted hand is the working side: as you gently shift bodyweight into it, the wrist moves into a controlled stretch instead of a loaded pressing pattern.

This stretch is useful after gripping work, push-ups, planks, climbing, racket sports, or any session that leaves the forearms feeling tight. The goal is not to crank the wrist into the deepest possible angle. The goal is to find a clean line of tension through the forearm flexors and the ulnar side of the wrist, then settle there long enough for the tissues to relax. A small change in hand angle, torso lean, or how far behind the hip the hand is placed can change where the stretch lands.

Set your base first. Keep the shoulders square, the chest lifted, and the elbow on the stretching side long enough to let the forearm lengthen, but not so locked that the joint feels jammed. From there, ease your body away from the hand or slightly into the hand, depending on which direction makes the stretch more obvious in the forearm rather than the thumb joint or the heel of the palm. If the position is correct, the sensation should stay broad and dull, not sharp.

Use a slow exhale to settle deeper, then hold the position without bouncing. This is a better cool-down choice than a power move, although a very gentle version can work in the warm-up when the wrists need to feel prepared before loading. If one wrist is noticeably tighter, work each side separately and match the hand placement carefully. Back off immediately if you feel numbness, tingling, or joint compression instead of a muscular stretch.

Instructions

• Sit on the floor or mat with both legs extended and place one hand on the floor beside or slightly behind the hip, palm flat and fingers turned to a comfortable angle.
• Stack the torso tall, keep the shoulders level, and keep the non-working hand resting on the thigh or floor for balance.
• Set the elbow on the stretching side long enough to lengthen the forearm, but do not force it into a hard lockout.
• Gently shift your bodyweight toward the posted hand until you feel a stretch along the forearm flexors and the pinky-side wrist.
• If the stretch feels too sharp at the wrist joint, adjust the hand a few degrees or slide it slightly closer to or farther from the hip.
• Use a slow exhale to settle into the end range and hold the position without bouncing.
• Keep the stretch broad and controlled rather than chasing the deepest possible angle.
• Release the hand gradually, reset your posture, and repeat on the other side if both wrists need work.

Tips & Tricks

• The stretch should show up through the forearm and the little-finger side of the wrist, not as a pinch in the thumb base or palm heel.
• A small change in how far behind the hip the hand is posted can make the stretch much easier or much harsher.
• If the shoulder creeps toward the ear, reset it down before you keep leaning.
• Keep the elbow long enough to open the forearm, but avoid snapping it into a hard lock.
• Use the exhale to relax into the position; do not force extra range on an inhale-hold.
• If the floor feels too aggressive, place the hand on a low bench or yoga block for a milder version.
• Stop if you feel numbness, tingling, or a sharp joint line sensation.
• This works well after sessions that involve heavy gripping, front rack work, planks, or hand support.

Frequently Asked Questions

What does the Seated Wrist Ulnar Deviator and Flexor Stretch target?

It mainly stretches the wrist flexors and the ulnar-side tissues of the forearm, especially near the pinky side of the wrist.

Where should I feel this stretch?

You should feel a broad stretch through the forearm and wrist, not a sharp pinch in the joint or thumb base.

Do I need to keep my hand flat and fingers turned a certain way?

Keep the palm flat and choose a finger angle that feels comfortable; a slight turn of the fingers can change the stretch target without changing the exercise.

Is this more of a warm-up or cool-down exercise?

It is usually better as a cool-down stretch, but a very gentle version can help prepare the wrists before loading.

How long should I hold each side?

A 15 to 30 second hold is a practical starting point, with a few relaxed rounds on each wrist if needed.

Can I do this if my wrists are sensitive?

Yes, but keep the lean small, place the hand closer to the body, or elevate the hand on a bench if the floor position feels too strong.

What is the most common mistake?

Most people either lean too hard and turn it into joint compression, or they let the shoulder shrug and lose the forearm stretch.

Should I do both wrists?

Usually yes, especially if you use both hands for pushing, gripping, or support work.
