This curl isolates the underside of the forearm using a palms-up grip and strict form.
Instructions
- Sit on a bench holding dumbbells with your forearms on your thighs, palms facing up.
- Let your wrists hang past your knees and curl them upward.
- Squeeze at the top, then lower slowly with control.
- Keep your forearms still — only your wrists should move.
- Repeat for the desired number of repetitions.
