Keeping the elbows slightly bent, lower the dumbbell in an arc back behind your head.
Stop when your upper arms are roughly in line with your torso or you feel a comfortable stretch.
Pull the dumbbell back along the same arc to above the chest.
Keep the ribs down and the hips on the bench throughout.
Breathing: Inhale as the dumbbell travels back, exhale as you pull it over the chest.
