When people come for massage the focus is very often on the back, neck and shoulders (BNS). These are the places where people generally feel the most tension and experience discomfort. However the pec muscles are often the key to good posture which will alleviate some of the tension in the BNS. When pec muscles are tight they naturally bring the shoulders forward and round. This makes you hunch, over-extend through the upper thoracic and your head moves forward into an emu like position.
Treatment of the pecs with massage can be uncomfortable, the great news is pecs respond well to stretching. So how do you stretch them correctly? There are three different sets of muscle fibres within the pec muscles so to stretch them properly you must also do the stretch three in different positions, not just one as is commonly the case.
