Massages also have a rejuvenating effect. When muscles are stressed, the fibers of the fascia that cover them suffer micro-tears. As they heal, these fibers become stronger, but they also can form scar tissue, called adhesions, which can limit your range of motion and cause discomfort. Deep pressure applied by a therapist to the fascia breaks up these adhesions. You're left feeling fresh and rejuvenated and ready to tackle the next big climb.
