Performing the: A Step-by-Step Tutorial Dumbbell Lying Pullover on Exercise Ball
Slowly walk your feet forward, rolling down the ball until only your upper back and shoulders are resting on it, your body forming a bridge position with your hips lifted.
Extend your arms above your chest, keeping a slight bend in your elbows and the dumbbell perpendicular to the floor.
Lower the dumbbell over and beyond your head until your upper arms are in line with your torso, inhaling as you do so.
Pull the dumbbell back to the initial position above your chest, exhaling as you do this, to complete one rep of the exercise.
