Start standing with feet hip-width apart and holding a dumbbell in each hand with a neutral grip (palms facing in). While maintaining a slight bend in your knees, hinge forward at the hips until your torso is almost parallel to the floor. Bend your elbows to bring the dumbbells to either side of your chest. This is your starting position.
Squeeze your triceps to extend your elbows and straighten your arms, ensuring that your upper arms remain in close contact with the sides of your body.
Relax your triceps to bend your elbows and return to the starting position. That's one rep.
