Put your upper back on a stability ball with bent knees and dumbbells in hand. Drop your hips down to three inches off the ground. Raise the dumbbells to shoulder height. Press the dumbbells straight up toward the ceiling. Once the dumbbells are directly above your chest, lower and repeat.
We love these adjustable dumbbells from Rep Fitness. They take up very little space and are also very durable compared to other adjustable dumbbells on the market.
