Step 1
Starting Position: Holding a dumbbell in the palms of both hands, lie supine (on your back) on a flat bench with your feet firmly placed on the floor. Slowly lift the dumbbell off your chest, fully extending your elbows until the dumbbell is positioned directly above your face and hangs vertically to the floor.
Step 2
Downward Phase: Inhale and slowly lower the dumbbell behind your head, bending at the elbows as the arms move back behind your head.
Step 3
Upward Phase: Exhale and slowly return to your starting position while maintaining the position of your torso on the bench.
Try to avoid your elbows flaring out. Keep your elbows within a few inches of each other throughout the exercise.
