Using plates, put a few fingers into the center holes of plates and start standing with both plates facing each other in front of you like you were clapping them together. Lift the plates to the side using your shoulders and upper back muscles. As they start to get towards the top, slightly internally rotate the shoulders and imagine you want to meet the back of your hands together over your head. This will not happen as the plates will touch beforehand. Lower the waits under control until your palms face each other low and in front of you. Repeat for repetitions.
