Pectoralis minor: A thin muscle on either side of the upper chest that is involved in the movement and stabilization of the scapula, or shoulder blade. Serratus anterior : A muscle that runs down ...
Pectoralis minor syndrome (PMS) is a condition related to thoracic outlet syndrome (TOS) that results from the pectoralis minor muscle being too tight. [1] PMS results from the brachial plexus being compressed under the pectoralis minor [2] while TOS involves compression of the bundle above the clavicle. In most patients, the nerves are ...
Chest pain is pain or discomfort in the chest, typically the front of the chest. [1] It may be described as sharp, dull, pressure, heaviness or squeezing. [ 3 ] Associated symptoms may include pain in the shoulder, arm, upper abdomen , or jaw, along with nausea , sweating, or shortness of breath .
Pain can also be in the side of the neck, the pectoral area below the clavicle, the armpit/axillary area, and the upper back (i.e., the trapezius and rhomboid area). Discoloration of the hands, one hand colder than the other hand, weakness of the hand and arm muscles, and tingling are commonly present.
Also known as 'effort angina', this refers to the classic type of angina related to myocardial ischemia.A typical presentation of stable angina is that of chest discomfort and associated symptoms precipitated by some activity (running, walking, etc.) with minimal or non-existent symptoms at rest or after administration of sublingual nitroglycerin.

The chest fly or pectoral fly (abbreviated to pec fly) primarily works the pectoralis major muscles to move the arms horizontally forward. If medially (internally) rotated, it is assisted in this by the anterior (front) head of the deltoideus in transverse flexion.
Pullovers can be made to affect either the chest or the back depending on how wide the grip is (barbell) and the position of the shoulders. A research done on the pullover movement using a barbell suggested more effect on the pectoralis major muscle as compared to the latissimus dorsi .
The pain is agitated by expansion and contraction of the chest. Taking a deep breath and allowing the rib cage to fully expand can relieve the pain, however it will feel unpleasant initially. At the point of full expansion, it can feel like a rubber band snap in the chest, after which the initial pain subsides.
