Finger Flexors
This is the most basic stretch for climbers, since it works the forearm muscles that enable finger flexion and your grip on the rock. Perform the stretch in the two positions described below.
1. Stand with arms relaxed by your sides.
2. Bring your arms together in front of your waist. Straighten the arm to be stretched and lay the fingertips into the palm of the opposite hand. Position the hand of the stretch arm so that it’s oriented palm-down with the thumb pointing inward.
3. Pull back on the fingers of your straight arm until the stretch begins in your forearm muscles. Hold this stretch for about twenty seconds.
4. Release the stretch and turn your hand 180 degrees so that your stretch arm is now positioned with the palm facing upward and the thumb pointing outward.
5. Again using the opposite hand, pull the fingers back until a stretch begins in the forearm muscles. Hold for twenty seconds.
6. Repeat this stretch, in both positions, with your other arm.
