Weighted Seated One Arm Wrist Curl
- Beginner

Muscles worked
Setup
- Sit on the edge of a flat bench with your feet planted firmly on the floor for stability.
- Grasp the edge of a weight plate with one hand using an underhand (palms-up) grip.
- Rest your forearm on your thigh or the bench so your wrist hangs just past the edge.
How to do it
- Inhale as you slowly lower the plate toward the floor by extending your wrist as far as comfortable.
- Exhale and curl the plate upward toward your forearm, squeezing the muscles at the top of the movement.
- Lower the weight back down with a controlled 2-second tempo to the starting position.
- Complete the desired number of repetitions on one arm before switching to the other.
Form checklist
- Keep your forearm pinned to your thigh or the bench; do not let the elbow lift.
- Ensure the movement occurs strictly at the wrist joint without body momentum.
- Maintain a firm, secure grip on the plate rim throughout the entire set.
- Use a full range of motion, from a deep stretch at the bottom to a full contraction at the top.
Pro tips
- At the bottom of the rep, let the plate roll slightly toward your fingertips to engage the deep finger flexors before curling back up.
- Focus on a hard peak contraction at the top of each rep to maximize muscle fiber recruitment in the forearms.
Make it harder
- Pause for two seconds at the peak of the contraction to increase time under tension.
- Use a thicker plate or a 'pinch grip' on the rim to further challenge your grip and thumb stability.
