One-Arm Wrist Curl Dumbbell

Sit on a bench with your feet flat on the floor, holding a dumbbell in one hand.

Rest your forearm on your thigh or a bench, with your wrist hanging over the edge and your palm facing upward.

Keep your forearm stationary and only move your wrist to ensure proper isolation of the wrist flexors.

Use a moderate weight that allows you to perform the exercise with good form throughout all repetitions.
