Come into a kneeling position on an exercise mat and tuck your toes under, so you're resting on the balls of your feet. Pin your left elbow to your side with your arm bent at 90 degrees and your palm facing up. Place your right hand under your left elbow for support. This is your start position. Proceed to slowly and with control move your wrist joint down into extension as much as you can, then across towards your little finger, then slowly up towards your forearm before going across towards your thumb. Perform this circular motion in both direction, working through the whole range of motion of your wrist. Make sure to only move the wrist joint without any compensation of movement in the elbow or shoulder joint. Repeat on both sides for the recommended amount of time.
