Kung Fu massage is a form of massage therapy that combines traditional Chinese Kung Fu techniques with massage techniques to provide a therapeutic treatment. This type of massage involves the use of pressure, stretching, and tapping techniques on specific points of the body to improve blood flow, release tension, and reduce pain.
The massage therapist may use their hands, elbows, knees, and feet to apply pressure to the body's muscles and joints. Kung Fu massage is often used to treat injuries and chronic pain, as well as to promote relaxation and wellness.
