Wrist Curls

Sit with the forearms resting on the thighs or on a bench and grasp the bar with an underhand grip with wrists relaxed:

• Inhale and raise the hands by flexing at the wrists.

This exercise contracts the flexor carpi radialis, palmaris longus, flexor carpi ulnaris, and the flexors digitorum superficialis and profundus. The latter two muscles, although located deep in the wrist, make up most of the muscle mass of the wrist flexors.
