Sit with forearms resting on your thighs or a bench. Take an underhand grip on one dumbbell, passively extending your wrists downward. Place the other hand on top of your wrist (not pictured) to hold the arm in place.
EXHALE: Curl your wrist up, keeping the rest of the arm still by using your free hand.
INHALE: Slowly lower to the starting position to complete one rep. Finish all reps on this side and switch hands.
Can also be done with both wrists simultaneously.
