Forearm - Supination - Articulations

How to do the Forearm - Supination - Articulations

1. 1Stand or sit tall with your upper arm tucked against your side and your elbow bent to 90 degrees.
2. 2Keep your elbow pinned to your ribs so the motion comes from the forearm, not the shoulder.
3. 3Start with your palm facing the floor (pronated) and your wrist relaxed in a neutral, straight line.
4. 4Slowly rotate your forearm outward so your palm turns to face the ceiling (supinated), pausing briefly at the end range.
5. 5Reverse the motion under control, rotating the palm back down to the starting position.
6. 6Repeat for smooth, controlled repetitions, breathing steadily throughout.
7. 7Switch arms and repeat the same number of rotations on the other side.

Form tips

• Move slowly through the full range rather than swinging — the goal is joint mobility, not speed.
• Keep your wrist neutral and your shoulder still so the rotation stays isolated to the forearm.
• Pause for a moment at full supination to gently feel the end range without forcing it.
• Use this as a warm-up before pressing, pulling, or grip work, or as light recovery between sessions.

Common mistakes

• Rotating from the shoulder instead of the forearm, which hides the supination range you are trying to mobilize.
• Letting the wrist bend or collapse during the turn, which shifts strain to the wrist joint instead of the forearm.
• Rushing through reps with momentum, so the tissues never spend time at the end range where mobility improves.
• Forcing past a sharp or painful end range, risking irritation of the elbow and forearm structures.
