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.

A track exercise device with at least first and second substantially parallel tracks, and first, second, third, and fourth movable platforms. The first and third movable platforms are movable on the first track, and the second and fourth movable platforms are movable on the second track. Transverse attachments selectively and respectively attach the first and second movable platforms together on the first and second tracks and the third and fourth movable platforms together on the first and second tracks. Longitudinal attachments selectively and respectively attach the first and third movable platforms together on the first track and the second and fourth movable platforms together on the second track. A tilting adjustment selectively provides for inclined or flat movement of the first, second, third, and fourth movable platforms.

An exercise device is described. An exercise device includes 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 edge 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 one or more wheels. Optionally, a shaft can be present that rotationally locks two or more of the wheels.

The present disclosure provides an elliptical crawler. The elliptical crawler includes a front support having an adjustable height and an assembly of elliptical rowing body having two extendible arm supports and two foot supports. Methods of making and using the elliptical crawler are also disclosed.

An exercise machine with electromagnetic resistance selection for changing exercise resistance settings by engaging more or fewer resistance biasing members using a electromagnets. An example implementation includes a movable carriage configured to move substantially along the length of one or more rails. A plurality of resistance biasing members are removably attachable between a stationary biasing member bracket affixed to the machine structure and the movable carriage. A controller changes the resistance settings against the movable carriage by electrically attaching or detaching any preferred number of resistance biasing members between the machine structure and movable carriage.

An exercise machine reversible resistance system for reversing the directional force of resistance against an exercise implement before, during, or after the performance of a routine of one or more exercises. The exercise machine reversible resistance system generally includes a frame, an elongated member movably positioned upon the frame, wherein the elongated member has a first run and a second run, a resistance device that applies a resistance force to the elongated member in a single direction, an exercise implement movably connected to the frame and a clutch connected to the exercise implement. The clutch is adapted to selectively engage the first run or the second run of the elongated member for selective control of the resistance direction of the exercise implement.

An exercise machine with adjustable platforms for adjusting the angular orientation of one or more end platforms and/or carriage platform to allow for a wide range of exercise moves. The exercise machine includes a rail to which a carriage is movably connected and a first end platform connected to an end of the rail. The carriage includes a platform which may be adjusted between a level position in which the platform is laid flat and a raised position in which the platform is at an angular incline. The first end platform may similarly and independently be adjustable between the level position in which the first end platform is laid flat and a raised position in which the first end platform is at an angular incline. In some embodiments, the exercise machine may include a second end platform which is similarly adjustable between a level position and a raised position.

An exercise machine carriage handle system for providing handles for an exerciser to grasp with their hands thereby expanding the type of exercises that may be performed. The exercise machine carriage handle system generally includes a frame having a track, a carriage movably connected to the track, a bias member connected between the frame and the carriage, a first handle connected to the carriage near the first side, and a second handle connected to the carriage near the second side. The first handle and second handle are adapted for grasping with a first hand and a second hand respectively of a user during the performance of an exercise on the exercise machine.

An exercise machine with adjustable platforms for adjusting the angular orientation of one or more end platforms and/or carriage platform to allow for a wide range of exercise moves. The exercise machine includes a rail to which a carriage is movably connected and a first end platform connected to an end of the rail. The carriage includes a platform which may be adjusted between a level position in which the platform is laid flat and a raised position in which the platform is at an angular incline. The first end platform may similarly and independently be adjustable between the level position in which the first end platform is laid flat and a raised position in which the first end platform is at an angular incline. In some embodiments, the exercise machine may include a second end platform which is similarly adjustable between a level position and a raised position.

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.
