Exercise of the Week: Seated Dumbbell Palms Down Wrist Curls
Sit on a flat bench while holding a dumbbell in each hand. Lay your forearms flat on your thighs with each dumbbell extending past your knees, palms down.
Using only your hands and wrists, simultaneously bring the dumbbells up toward the ceiling as high as possible, keeping your forearms flat on your thighs.
Return to the start position and repeat until failure.
