An exercise system includes a frame, an upper body carriage, a lower body carriage, a positioning carriage, a resistance assembly attached to the frame, and a connecting mechanism. The frame includes a right guide rail, a left guide rail, and a central guide rail disposed between the right guide rail and the left guide rail. The upper body carriage includes an upper right and an upper left carriage slidingly attached to the right and left guide rail, respectively. The lower body carriage includes a lower right and lower left carriage slidingly attached to the right and left guide rail, respectively. The connecting mechanism mechanically couples one of the upper body carriage, the lower body carriage, or the carriage to the resistance assembly such that the resistance assembly applies a predetermined level of resistive force to the upper body carriage, the lower body carriage, and/or the tension carriage.

An exercise device including a body engagement portion that can support a user, and a guide track assembly that can rotationally house the body engagement portion. The body engagement portion includes a base surface and a rotation support assembly. The base surface may support the user in a standard plank position. The body engagement portion may allow a user to rotate between a first side plank position, the standard plank position, and a second side plank position relative to a support surface while the guide track assembly remain in contact with the support surface and the body engagement portion support upper body of the user. The body engagement portion may allow a user to statically hold a plank position or rotate between two plank positions at any angle equal to, or between, the first side plank position, the standard plank position, and the second side plank position.

An exercise machine with multiple contact surfaces for providing secondary exercise support platforms positioned at various planes relative to the horizontal plane of the primary exercising platforms, the secondary platforms further serving as handles used during the performance of exercises. The exercise machine with multiple contact surfaces generally includes a frame, a carriage movably attached to the rail, and a first support structure and a second support structure attached to the frame near the first end. The support structures each include one or more platforms having an upper surface that is positioned above the base plane of the carriage.

An exercise machine support system for providing increased versatility including inclination or declination of an exercise surface, a reduction in the overall length and width of the exercise machine, and an enhanced user interface which reduces the risk of injury. The exercise machine support system generally includes a cantilevered exercise machine which is adapted to have a variable angle of incline or decline with respect to a horizontal ground surface. The exercise machine will generally include a base and a support which extends between the base and the exercise machine. The upper end of the support is connected to the exercise machine by a first pivot such that the exercise machine pivots about the support. An adjustment device may be utilized to pivot the exercise machine and thus adjust its angle of incline. Various types of adjustment devices are disclosed, including an actuator, ratchet-and-pawl, gears, and cam.

A system and method of using two exercise machines for performing a wide range of exercise movements that utilize both of the exercise machines in concert. The system and method of using two exercise machines generally includes first exercise machine and a second exercise machine which are used in concert to perform a wide range of exercise movements. The first exercise machine may include a track, a carriage movably connected to the track, and an end platform. The second exercise machine may include its own separate track, a carriage movably connected to the track, and an end platform. The exercise machines may be positioned side-to-side in parallel orientation such that an exerciser may perform various exercise moves by positioning different limbs on the respective carriages, end platforms, and/or tracks of the exercise machines, in addition to the surface underlying the exercise machines.

An exercise machine rail system for improved exerciser mounting and dismounting, improved functional ergonomics, and reduced risk of exerciser injury when using an exercise machine. The exercise machine rail system generally includes either two rails in close relationship which are linked together via connectors or a singular rail. Bias members are disclosed as either extending along either outer side of the rails, internally to the rail, or underneath the rail. Due to the narrow nature of the rails used by the present invention, an exerciser is able to mount and dismount the exercise machine easily and efficiently.

An exercise machine which allows for a wide range of exercises while maintaining improved balance and control for the exerciser. The exercise machine generally includes a frame having a first track, a carriage movably connected to the first track, a first platform and a second platform connected to the frame, a first stationary handle extending upwardly from the upper surface of the first platform, and a second stationary handle extending upwardly from the upper surface of the first platform.

An exercise device is described. An exercise device including a body, the body having a top, a bottom, a first end located at one edge of the body, a second end located at an opposite end of the body, and first and second sides extending between the first and second ends; one or more wheels; and an energy storage device applying resistive and restoring force to the wheel. Optionally, a shaft can be present that rotationally locks two or more of the wheels.

An exercise device is described which includes a platform having a first end and a second end opposite the first end; first and second wheels, wherein the first wheel is positioned proximate the first end and the second wheel is positioned proximate the second end and the first and second wheels are configured to roll across a surface as the exercise device is displaced along the surface; a first motor configured to apply a first torque to the first wheel where the magnitude of the first torque is related to the distance of the exercise device from a zero position and the direction of the first torque urges movement of the exercise device toward the zero position. Versions are also described with more wheels and more motors.
