19 Claims

1. An exercise device, comprising:

a base;

an exercise machine movably connected to the base, wherein the exercise machine comprises a track, a carriage slidably connected to the track, a biasing member adapted to be connected to the carriage to apply a resistive force to the carriage, and an end platform near a first end of the exercise machine; and

a plurality of actuators connected between the base and the exercise machine, wherein each of the plurality of actuators is movably connected to the base by a first articulating connector and movably connected to the exercise machine by a second articulating connector;

wherein the plurality of actuators are operable to move the exercise machine about a first axis with respect to the base and a second axis with respect to the base, wherein the first axis is comprised of a pitch axis of the exercise machine and wherein the second axis is comprised of a roll axis of the exercise machine;

wherein the plurality of actuators comprises a first actuator, a second actuator, a third actuator and a fourth actuator;

wherein the first actuator and the third actuator are connected closer to the first end of the exercise machine than a second end of the exercise machine, and wherein the second actuator and the fourth actuator are connected closer to the second end of the exercise machine than the first end of the exercise machine;

wherein the first actuator and the second actuator are connected near a first side of the exercise machine, and wherein the third actuator and the fourth actuator are connected near a second side of the exercise machine;

wherein the first actuator and the third actuator are adapted to together lift and lower the first end of the exercise machine, and wherein the second actuator and the fourth actuator are adapted to together lift and lower the second end of the exercise machine;

wherein the first actuator, the second actuator, the third actuator and the fourth actuator are adapted to together lift and lower the exercise machine along a vertical axis at a constant angle of inclination;

wherein the first actuator and the third actuator each extend outwardly from the base toward the first end of the exercise machine; and

wherein the second actuator and the fourth actuator each extend outwardly from the base toward the second end of the exercise machine.
