SETUP: Grab either side of a plate and hold it just above your head. A split-stance position will help support your lower back and allow you to focus on your shoulders more.
LIFT: Rotate the weight around your head, keeping it elevated until the end of the set. I mostly program this exercise for time, but if working with reps count one rotation as one.
TIP: You can change direction on a rep-by-rep basis, or perform a full set then switch.
