STARTING POSITION:
Select the appropriate weight of the dumbbell. Sit on a chair next to a table at your chest high. Grab the dumbbell with your right hand. Now place your right forearm supine on the table, letting your hand hang outside the table.
MOVEMENT:
Helped by your left hand, fully bend your wrist. Drop the hand and return to the starting position in a smooth movement. Repeat the movement for the specified amount of repetitions, then switch sides and repeat the exercise.
TIPS: The exercise key is quality over quantity. The trick is to perform the exercise using proper form. To increase the level of the exercise, add more tension to the elastic band.
