A system and a method of treatment using a universal cage creating a coordinate method of exercise. Physical therapy or fitness exercises are provided to a patient through a system of cords, blocks and belts disposed on a plurality of grid panels through a plurality of mounting devices. Placement of the mounting devices on the grid panel is determined by which muscle groups are receiving therapy and the type of movement required. Once the placement for each movement is determined, the coordinates of the mounting device are captured so that the mounting devices can be preset consistently for each therapy session.
