Overview
This exercise loads the wrist extensor muscles that attach near the outside of the elbow, but the wrist does not move. It can be a useful starting point when repeated gripping or wrist motion is irritable.
How to Do It
- Sit with the forearm supported and the palm facing down.
- Keep the wrist in a comfortable neutral position.
- Place the other hand over the back of the working hand.
- Try to lift the working hand while the other hand prevents movement.
- Hold for 20–30 seconds at a light-to-moderate effort.
- Rest, then repeat 3–5 times.
What You Should Feel
You should feel the upper forearm working. Mild, stable discomfort near the outside of the elbow may be tolerable for some people; sharp or steadily increasing pain is not the goal.
Common Mistakes
- Pressing at maximum effort from the first repetition
- Letting the wrist bend while calling it an isometric
- Shrugging or gripping harder than necessary
- Continuing when symptoms spread, strength suddenly drops or technique changes
Progression
Increase the effort slightly before increasing hold time. When static holds are comfortable, progress toward slow wrist-extension repetitions with light resistance and then task-specific gripping.
