Equipment
Setup
- Sit or kneel next to a flat surface like a table, or use your own thigh as a support.
- Rest your forearm on the surface with your palm facing down and your wrist hanging just over the edge.
- Make a light fist with your working hand to keep the tension in the forearm muscles.
How to do it
- Exhale as you lift the back of your hand toward the ceiling, moving only at the wrist joint.
- Squeeze the top of the forearm at the peak of the movement for one second.
- Inhale as you slowly lower your hand back down to the starting position using a controlled 3-second tempo.
Form checklist
- Keep your forearm flat against the support throughout the entire set.
- Ensure the movement is strictly coming from the wrist, not the elbow or shoulder.
- Maintain a full range of motion, allowing the wrist to dip slightly below the edge at the bottom.
Pro tips
- Focus on the mind-muscle connection by visualizing the muscles on the top of your forearm shortening as you lift.
- Keep your thumb tucked or wrapped to ensure the extensors are doing the work rather than the finger muscles.
Make it harder
- Use your opposite hand to provide light manual resistance against the back of your hand during the upward phase.
- Slow down the eccentric (lowering) phase to 5 seconds to increase time under tension.
