Setup
- Kneel on the floor perpendicular to a flat bench.
- Place your forearm flat across the bench with your wrist hanging just off the edge.
- Hold a dumbbell with a neutral grip, meaning your palm faces inward and your thumb points toward the ceiling.
- Use your non-working hand to stabilize your forearm against the bench to prevent the elbow from lifting.
How to do it
- Inhale as you slowly lower the dumbbell toward the floor by extending your wrist as far as your range of motion allows.
- Exhale as you curl the dumbbell upward toward the ceiling, focusing on pulling the thumb side of your hand toward your forearm.
- Maintain a controlled tempo, taking two seconds to lower the weight and two seconds to lift it.
- Complete all reps on one arm before switching to the other.
Form checklist
- Keep your forearm pinned to the bench throughout the entire movement.
- Ensure the movement is isolated to the wrist joint; do not involve the elbow or shoulder.
- Maintain a firm, neutral grip without letting the wrist rotate into a palms-up or palms-down position.
- Avoid using body momentum or 'swinging' the weight to complete the rep.
Pro tips
- Focus on the 'radial deviation' movement—squeezing the thumb side of the hand toward the forearm—to maximize brachioradialis engagement.
- Squeeze the dumbbell handle as hard as possible at the peak of the contraction to increase muscle fiber recruitment.
Make it harder
- Add a three-second isometric hold at the top of each repetition to increase time under tension.
- Use a 'fat grip' attachment or wrap a small towel around the dumbbell handle to further challenge your grip strength.
