Deep tissue is a massage technique that is mainly used to treat musculoskeletal issues. Such examples can be strains or sports injuries. It involves applying sustained slow, deep strokes to target the inner layers of your muscles and connective tissue. It also promotes healing by increasing blood flow. Deep tissue involved deep kneading and stroking using various amounts of intense pressure. It is not unusual to have some soreness after a deep tissue massage. Deep tissue massage is best suited for people who engage in highly physical activities or have chronic lingering pain.
