How is the muscle trained / contracted?

Like the lower bone, the upper bone is a muscle that is not given special attention in weight training. Only in the definition phase in bodybuilding is specific attention paid to the development of individual muscles. The upper bone muscle is stressed during abduction in the shoulder joint and therefore the following exercise is recommended.
