Most of us like a random shoulder massage. It seems like we have a constant tension in this region. Specifically when we are stressed.
So why the shoulders? Why not the legs, arms or stomach? And where does tension come from, anyway?

So first off I am a Massage Therapist. And this is actually incredibly easy to explain…..physically the pec muscles are just Two muscles one really big (Pec Major) and a smaller (Pec Minor) underneath it… now these muscle really only have one direction they go…..
The back has a few muscle groups yes
Traps, rhomboid, erectors, and the on the scapula you have the infra and supraspinatous teres major minor….anyways you get the just all these muscles have an attachment to pull the shoulders back in some way…… but they are all in different directions and not as strong as the Pec Major…….
Add in the fact that humans are lazy and forward orientated everything we do is in front of us. Forcing the pec muscles to co tract and pull shoulder forward. Then the muscles in back being as weak compared try to pull back and just can’t so they stay locked or get distorted by knots and over stretching.
