"Get Off My Back"
This exercise works well after the arms and shoulders are loosed up by other exercises. Stand loosely, with feet about shoulder width apart, knees slightly bent, and weight forward on the balls of the feet. Bend elbows, then raise out to the sides until they are about shoulder height. Push elbows backwards as if warding off someone, giving strong vocal expression to the phrase "Get off my back" or something similar. Try to use the shoulder blades and upper back and not just the arms.
Rationale: Anger is held in the upper back, and this exercise aims to free those areas. Unlike forward movement of the arms, it is not possible to move the arms behnd the body without using the upper corners of the torso, which are after all, the beginning of the arms.
