A common climbing problem is pain on the inside portion of the wrist. Sometimes this pain can be a result to damage to the red circle – or TFCC, which is a cartilage structure on the pinky finger side of the wrist. It&;s function is to support and cushion the small bones of the wrist and stabilize the bones of the forearm (radius and ulna) when the hand grasps or the forearm rotates. It&;s important to strengthen the wrist in more than just flexion and extension. When doing this exercise you are working your wrist using radial and ulnar deviation. Keep in mind the following:Stabilize the forearmSmooth, steady controlled motionGrab closer to the CENTER of the stick for an EASIER exercise Grab closer to the END of the stick for a HARDER exercise Rinse and repeat 20 times as part of your warm up or for sets as an integral part of wrist maintenance series
