Elbow Extension And Supination Pronation Forearm Stretch

Muscles worked

Setup

1. Stand or sit upright with a neutral spine and relaxed shoulders.
2. Extend one arm directly in front of you at shoulder height.
3. Lock your elbow completely to ensure the rotation occurs at the forearm rather than the upper arm.
4. Keep your hand in a neutral position with fingers extended or a very light fist.

How to do it

1. Slowly rotate your forearm outward (supination) until your palm faces upward, exhaling as you reach the end of the range.
2. Hold the supinated position for 1-2 seconds to feel the stretch in the inner forearm.
3. Slowly rotate your forearm inward (pronation) until your palm faces downward or slightly outward, inhaling during the transition.
4. Perform the movement for the prescribed repetitions or time, then switch to the other arm.

Form checklist

• Keep the elbow fully extended; do not allow it to bend during rotation.
• Ensure the shoulder remains stable and does not rotate or shrug upward.
• Move at a slow, controlled tempo to avoid snapping the joint at end-ranges.
• Maintain a tall posture with your core lightly engaged.

Pro tips

• To increase the stretch, spread your fingers wide as you rotate to engage the fascia of the palm and wrist.
• Focus on the 'end-feel' of the rotation, pushing gently into the limit of your range of motion to improve joint capsule mobility.

Make it harder

• Hold a light, unbalanced object (like a hammer or a water bottle held at the base) to add resistance to the rotation.
• Perform the rotation while simultaneously pulling your wrist into full extension or flexion to intensify the stretch along the forearm lines.
