How to do it
Stand tall holding a light dumbbell, raise your upper arm out to the side until your elbow is level with your shoulder and bent at 90 degrees. Keeping the elbow at shoulder height, rotate your forearm upward and back so your knuckles point toward the ceiling, then lower the forearm forward with control and repeat.
