Stand up straight with the water at chest depth and your feet shoulder-width apart.
Hold a dumbbell float in your affected hand and bend down into a squat position.
Reach for your opposite knee with the dumbbell.
Next, simultaneously stand up straight while you pull your shoulder blade down towards your opposite buttock, rotating from your trunk.
Reach your arm with the dumbbell float up and out, rotating your upper body to the same side as you do this.
Squat back down, and repeat.
