An exercise device having a unique asymmetrical shape with rounded ends of differing radii to provide stability and added resistance.

An exercise machine is described that incorporates a double retractable resistance band system for rowing exercises and that includes a multi-purpose, morphable swinging seat assembly that applies to convertible exercise machines and rowing boats. The double retractable rowing system is detachably integrated into a base plate (inclined planar board) of the exercise machine. The base plate consists of a platform set at an angle consistent with the foot-placements of sit-down rowing machines and rowing shells together with an integral set of quick-release slots located above and to the outside of the toes of the foot placement positions. The multi-purpose, morphable swinging seat assembly provides an improved method/structural assembly for seat-based rowing machines, convertible/multi-purpose exercise machines and an improved architecture for boat-based rowing systems.

A novel rowing machine attachment includes a bracket for attaching to a roller assembly of a rowing machine and a receiver for attaching to a handle of a rowing machine. In a particular embodiment, the bracket fixably attaches to the roller assembly and the receiver releasably attaches to the bracket for selective use. In a more particular embodiment, the bracket and the receiver are both integral parts of a single rigid body structure.

Exercise device, having at least one elongate track onto which a seat and a footrest are slidingly movably arranged, such that the seat and the footrest are mutually independently movable along the at least one track, a resistance element connected to a handle via a drive cord through which the resistance element can be driven upon pulling the handle towards the seat, and a cord guiding member arranged between the handle and the resistance element over which the drive cord passes, wherein the cord guiding member is arranged stationary with respect to the footrest, and wherein the resistance element is arranged stationary with respect to the at least one track.

A reversible resistance exercise machine for reversing the direction of applied resistance against a movable platform of an exercising machine. The exercise machine has a frame, a carriage movably positioned upon the frame, and a plurality of biasing members. A plurality of first tension connectors are accessible near the first end of the carriage and are adapted for removably attaching selected biasing members near the first end of the carriage to resist motion of the carriage in the first direction. A plurality of second tension connectors are accessible near the second end of the carriage and are adapted for removably attaching selected biasing members near the second end of the carriage to resist motion of the carriage in the second direction. A user selectable amount of force may be applied to the carriage to resist movement in either of the first direction and the second direction.

An exercise device system comprising a tower; a support structure inclinable at different angles relative to the tower; a movable user support platform movably associated with the support structure for movement relative to the support structure; a pulley system associated with the movable user support platform; a cable extending through the pulley system and including opposite ends; exercise device handles coupled to the opposite ends of the cable, whereby movement of the handles causes movement of the movable user support platform relative to the support structure.

A rowing machine is disclosed. The rowing machine includes a frame including a base for contact with a support surface and a seat rail supported by the base. The rowing machine includes a seat configured to reciprocate back and forth along the seat rail. The rowing machine includes a rowing engine that includes at least one resistance mechanism rotatably coupled to the frame. The rowing machine includes at least one handle operatively connected to the at least one resistance mechanism, and a paddle linkage assembly operatively connecting the at least one handle to the at least one resistance mechanism such that rearward movement of the handle is resisted by the at least one resistance mechanism.

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 rowing exercise assembly for includes a pair of elevation units that is each positionable at a selected point between a minimum elevation and a maximum elevation. A rowing machine is coupled between each of the elevation units thereby facilitating the rowing machine to be positionable at a variety of horizontal angles. In this way the elevation units enhance rowing exercises. A pair of cables is each of the cables is coupled to the resistance unit. A pair of handles is each coupled to a respective one of the cables and each of the handles may be gripped for performing rowing exercises. A control is positioned proximate the rowing machine and each of the elevation units is electrically coupled to the control. Moreover, the control actuates each of the elevation units to be positioned at the selected point between the minimum and maximum elevations.
