Pictured above is the pectoralis minor. It is a stabilizing muscle for the shoulder blade (scapula) and it pulls the top front of the scapula down toward the front center of the chest. It is hugely impactful on proper shoulder posture and range of motion. If you are dealing with shoulder or neck issues, you MUST address this muscle on a regular basis. (click here for a list of all the muscles)
The muscles are layered, showing how some of the muscles are covered by the others. All of the muscles are see-through so that you can appreciate the location and size of each muscle relative to the others.
