  "description": "Seated at a desk, place the palm flat on the desktop with the fingers pointing back toward the body and the elbow straight, then gently lean away from the hand to draw the wrist into extension and stretch the palm-side forearm flexors. The desk supplies the counter-pressure so the stretch is fully passive and easy to grade by how far you lean.",
