Barbell Palms Down Wrist Curl Over A Bench

Sit on a bench with your feet flat on the ground and your forearms resting on your thighs, palms facing down.

Hold a barbell with an overhand grip, hands shoulder-width apart.

Lower the barbell towards the ground by flexing your wrists, keeping your forearms stationary.

Pause for a moment at the bottom, then slowly raise the barbell back up by extending your wrists.

Repeat for the desired number of repetitions.
