To think of massage as something you only do with your hands is incorrect. A therapist who uses the hands for a palpation tool and the whole body for most of the pressure is working correctly. Massage is very physical and the muscles of the arms should not be used for long periods of time without taking a break. The arm muscles are not generally aerobic and fatigue easily; however, the large muscles of the legs and hips can function efficiently for many hours at a time. Generate your power from the lower body to help prevent injury and excessive strain to your arms and hands.
