An exercise system that may be rail-less, frameless, and/or portable is described. The exercise system includes a carriage having a plurality of wheels and a stationary platform. The stationary platform is independent of and separate from the carriage, and the stationary platform is freestanding. At least one tension member having a first end is attached to the carriage and a second end is detachably attached to the platform such that the carriage is movable on a horizontal plane parallel to a ground surface while the stationary platform remains in a fixed position.

An exercise machine rail indicia system for providing indicia to improve exercise instruction. The exercise machine rail indicia system generally includes a frame a rail, a carriage movably positioned upon the rail, a bias member connected between the carriage and the frame that applies a bias force upon the carriage, a first position indicator positioned upon the upper surface of the rail, and a second position indicator positioned upon the upper surface of the rail. The first position indicator and the second position indicator are distally spaced apart a first distance. The first position indicator and the second position indicator visually indicate to the exerciser where to position the carriage along the first rail during the performance of an exercise.

An exercise machine with adjustable handles that provide for multiple handle positions. The exercise machine with adjustable handles generally includes a frame with one or more rails, a carriage movably positioned upon the rails, and a pair of adjustable handles positioned near an end of the frame. The adjustable handles each have a handle portion that is movably connected to a corresponding handle stanchion to pivot from a storage position to an extended position.

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.

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 resistance selector system for selecting the number of bias members applying a resistance force against a movable platform. The exercise machine with resistance selector system generally includes one or more switches which are connected to the movable platform. Each of the one or more switches is adapted to engage or disengage a corresponding latch. When engaged, the latch will connect a corresponding bias member to the movable platform. When disengaged, the latch will disconnect a corresponding bias member from the movable platform. In this manner, an exerciser may easily adjust the number of bias members connected to the movable platform so as to adjust the resistance force applied against movement of the movable platform along a rail.

The present invention relates to the field of fitness training devices and exercise machines. More specifically, a substantially horizontal exercise machine comprising an exercise platform slidable along one or more rails aligned with the longitudinal axis of the machine structure, the slidable platform spring-biased towards one end of the machine, is tiltable to allow for one end of the machine to be raised or lowered relative to the opposed end of the machine.

An exercise machine resistance adjustment system for providing an exerciser the ability to immediately adjust the resistance force by changing their body position on the movable carriage or end platforms. The exercise machine resistance adjustment system generally includes a frame, a carriage movably positioned on the frame, a spring connected to the carriage to apply a biasing force to the carriage, one or more left projections within the carriage adapted for a left hand of an exerciser to grasp, and one or more right projections within the carriage adapted for a right hand of an exerciser to grasp. The exerciser is able to efficiently adjust the amount of resistance force applied to the carriage by repositioning their hands (or feet) from a first set of projections at a first distance to a second set of projections at a second distance from the first end of the exercise machine.

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.

A range of motion limiting device, in one example comprising a first armature configured to engage a carriage moving on at least one rail having a first surface and a second surface transversely offset from the first surface of the rail. Also disclosed is an example utilizing a first bumper adjacent the first longitudinal end of the first armature. The first bumper extending transversely from the first transverse side of the first armature, optionally having a distal end with a non-slip surface engaging the first surface of a rail. Also disclosed is a second bumper longitudinally offset from the first bumper on the first armature, the second bumper extending transversely from the second transverse side of the first armature, also optionally having a distal end with a non-slip surface engaging the second surface of the rail.
