Isometric Wrist Extension

Muscles worked

Setup

1. Sit on a bench and rest your forearm flat against your thigh or the bench surface.
2. Position your wrist so your hand hangs just off the edge with your palm facing the floor.
3. Make a loose fist with the working hand to pre-engage the forearm muscles.

How to do it

1. Place your non-working hand on top of the knuckles of your working hand to provide resistance.
2. Attempt to lift your working hand upward into extension while simultaneously pushing down with your non-working hand to prevent any actual movement.
3. Maintain this maximum static contraction for the prescribed duration while breathing deeply and steadily.
4. Release the tension slowly before switching to the other arm.

Form checklist

• Keep the forearm glued to the supporting surface throughout the hold.
• Ensure the wrist remains in a neutral position, not allowing it to be pushed into flexion.
• Avoid shrugging the shoulders or using body weight to create resistance.
• Maintain a firm but controlled grip with the resisting hand.

Pro tips

• Focus on the mind-muscle connection by visualizing the muscles on the top of your forearm hardening like stone.
• Gradually ramp up the intensity of the contraction over the first 3-5 seconds rather than exploding into the hold.

Make it harder

• Increase the duration of the hold to 45-60 seconds to prioritize muscular endurance and tendon loading.
• Perform the isometric hold at different angles, such as slightly more extended, to challenge the muscle at various lengths.
