Exercise VI: Bentover Dumbbell Raise
Hold a dumbbell in each hand and, keeping your lower back in its natural arch, bend over at the hips until your torso is about 45 degrees to the floor and allow your arms to hang with your palms facing your knees . Squeeze your shoulder blades together and raise your upper arms until they are parallel to the floor (the heel of your hands should face the ceiling) . Reverse the motion to return to the starting position. That's one rep.
