Disclosed herein are various embodiments of an exercise apparatus. In certain embodiments, an exercise apparatus comprises a frame and a seat assembly, the seat assembly comprising a seat, the seat configured to move between a first position and a second position, wherein the first position accommodates use of the exercise apparatus by a user sitting on the seat and wherein the second position accommodates use of the exercise apparatus by a user sitting in a wheelchair. The seat assembly may be pivotably coupled to the frame. The seat assembly may comprise a stop configured to inhibit movement of the seat, and may further comprise a biasing element that is biased to disengage the stop.

An exercise machine has a mobile base and an upright support extending upwards from the mobile base. An upper support assembly extends forward from an upper portion of the upright support and an exercise device is suspended from the upper support assembly at a location spaced forward from the upright support. The exercise machine may include a compact and safe counterbalancing gas spring mechanism that tends to move the exercise device away from the exerciser, and that requires a force to be applied to move an exercise device down towards the exerciser. The exercise machine may include an exercise device that is rotatable along a vertical axis, and may be coupled to an adjustable monitor for a wide range of uses. The exercise machine may be used by a exerciser lying supine, sitting in a chair or wheelchair, or standing in front of or adjacent the exercise machine.

A vehicle seat assembly includes a seat base, a seat back rotatably connected to the seat base, a seat bottom mounted on the seat base, and at least one of the following mounted to one of the seat base, seat back, and seat bottom: a resistance mechanism structured to exert a biasing force on at least one exercise arm operatively connected to the resistance mechanism; a bicycle seat receptacle structured for detachably mounting a bicycle seat to the seat base; and a docking mechanism structured for detachably mounting a pedal mechanism to the seat base.

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.

A rowing exercise machine includes a base frame, a paddle unit, a first rotating shaft, a paddle linkage unit, a resistance unit, a pull bar unit, a second rotating shaft, and a pull bar linkage unit. When a first operating force is applied to the paddle unit, a paddle one-way driving wheel and the first rotating shaft are driven to rotate in a first rotational direction. When the first operating force disappears, the paddle one-way driving wheel is idling on the first rotating shaft in a second rotational direction. When a second operating force is applied to the pull bar unit, the pull bar linkage unit is driven to rotate in the first rotational direction. When the second operating force disappears, a second return force drives a pull bar one-way wheel to be idling on the second rotating shaft in the second rotational direction.

An exercise apparatus (5) comprising: a user input device (5i) mounted to a frame for movement in a first direction (6f) and for movement in a second direction (6o) that is generally opposite the first direction (6f), the user input device (5i) comprising a manually engageable device (5e) interconnected to a first fan (20) adapted to be rotatably driven to exert a first resistance (R1) on rotation in one direction and a second fan (22) adapted to be rotatably driven to exert a second resistance (R2) on rotation in one direction.

Disclosed herein are various embodiments of an exercise apparatus. In certain embodiments, an exercise apparatus comprises a frame and a seat assembly, the seat assembly comprising a seat, the seat configured to move between a first position and a second position, wherein the first position accommodates use of the exercise apparatus by a user sitting on the seat and wherein the second position accommodates use of the exercise apparatus by a user sitting in a wheelchair. The seat assembly may be pivotably coupled to the frame. The seat assembly may comprise a stop configured to inhibit movement of the seat, and may further comprise a biasing element that is biased to disengage the stop.

This invention offers a rowing machine's mechanical resistance device which comprises an electric motor or a solenoid, a programmable control means and a custom algorithm, controlling the programmable controls means. It eliminates the compromising effect of backlash between the rower's handle and the resistance imparting device. This backlash is present between the power and the idle phases of rowing strokes on all state of the art rowing machines comprising flywheels. Ultimately, this invention allows all rowers to improve their rowing form and avoid injury.
