Using deeper and more direct pressure, this highly therapeutic massage helps to relieve muscular tension and pain by spreading constricted muscle fibers. Releasing adhesions and stretching thickened and shortened fascia can help increase your mobility and flexibility. Deep tissue work can improve breathing and posture, and creates the opportunity for change and new movement patterns. A deep tissue massage usually concentrates on the specific muscle groups that are affected. Expect some soreness for a day or two.
