Instructions

Sit down on a bench with a dumbbell in each hand, resting them on top of your thighs. Lie back on the bench and raise the dumbbells up above you, positioned over your chest with your arms fully extended and your palms facing away from you. Keeping a natural curve in your back, tuck your shoulder blades back and down and push your feet in to the floor. Lower one of the dumbbells in an arc shape down to the side of your chest. From here, press the dumbbell back up in the same arc pattern to the starting position. Repeat on the other side, then repeat for the desired number of repetitions.
