Massage systems and methods for massaging a person's body include a massaging unit coupled to an processing module and a power supply. First and second actuators are housed in the first massaging unit. The first actuator applies a moving pressure to the person's body to create a first trace, and simultaneously, the second actuator applies a moving pressure to the person's body to create a second. The first trace comprises a first segment of a perimeter of a rectangle from a first corner of the rectangle to a midpoint of a first edge that is adjacent to the first corner. The second trace comprises a second segment of the perimeter of the rectangle from a second corner of the rectangle to a midpoint of a second edge that is adjacent to the second corner, and the first and second edges are parallel.
