Educational diagram illustrating three wrist positions (neutral, extension, flexion) holding a pulley cable handle, with arrows.

“Create a clean educational diagram of a right forearm and hand holding a cylindrical arm-wrestling handle attached to a ceiling pulley cable. Show three side-by-side positions, all with the forearm horizontal in the air: Neutral wrist position: forearm and hand in a straight line from elbow to middle finger. Slightly opened wrist (about 20 degrees extension): the hand bent slightly backward away from the palm, showing the cable trying to open the wrist while the wrist is resisting. Slightly cupped wrist (about 20 degrees flexion): the hand bent slightly forward toward the palm, clearly different from the opened position. Use clear arrows to show direction of movement for opening vs cupping. Style should be simple, realistic, medical or sports-anatomy illustration, neutral background, good lighting, no clutter. The handle should be clearly visible in all three positions, and the wrist angle difference should be obvious. Do NOT exaggerate angles. Show realistic, subtle wrist positions used in arm-wrestling training.” See more
