Why even bother with pectoral massage? Pectoral minor muscles attach to the shoulder blade and ribs, and help move shoulders down andforward. They also help with breathing. With modern lifestyles dominated by computers, smartphones, and driving, our shoulders spend way too much time in a hunched position.
Pectoral muscles often become tightened and short. At the same time, muscles of the upper back, neck, and shoulders are also tight and stiff from this position. Pectoral and back/shoulder muscles balance each other. So if you get a massage that relieves tension in the shoulder and upper back but doesn’t address the pectoral muscles you’ve only addressed part of the problem.
Want to relieve tension in your pecs on your own? Try one of these stretches.
And simple forward and backward shoulder rolls are great for loosening up shoulders and associated muscles (including pectorals).
A further note: A few professional massage therapists offer breast massage for special medical conditions. It is a very specialized practice, and not a part of typical massage. A separate release form is often used.
