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.

Stationary exercise machine. In one aspect of the disclosure, a stationary exercise machine may include one or more moveable members configured to be moved by a user, an actuator configured to selectively adjust the speed of, or the amount of resistance on, the one or more moveable members, and one or more processors. The one or more processors may be configured to receive a video, execute the video set to a first difficulty level, receive a second difficulty level, and execute the video reset to the second difficulty level.

An illumination device for directing light into a transparent fluid tank of a fluid-resistance exercise machine is disclosed. The device can be coupled with an exterior surface of the tank and includes a light source oriented to project light through a surface and into a region of the fluid tank where the light can be observed by a user of the machine during operation, especially when a rotary device disturbs the fluid to generate the fluid resistance effect. The illumination device can include a control unit having a processor and a communication device, where the communication device receives an exercise-related parameter relayed during operation of the exercise machine. In response the control unit can dynamically adjust a quality of the light as a function of the received parameter, such as heartrate, output, resistance, time, distance, or speed.

The air pressure systems comprise a chamber for receiving at least a portion of a user's body. Pressure in the chamber can be changed to adjust force on the user's body. Described herein are various methods and related structures for sealing a user into a pressurizable chamber. Also described herein are various methods and related structures for changing the shape and/or height of the chamber. Described herein are various types and configurations of chambers and support structures for chambers. Also described herein are various methods and related systems for treating various conditions using the differential air pressure systems, including but not limited to obesity, cardiac disease, multiple sclerosis, cerebral palsy, or Down Syndrome.

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 footrest includes a base plate, two supports and two clipless pedals. The base plate has a first set of adjustment holes arranged in two rows. Each of the supports has a bottom and a pivoting seat. The bottom has two fixing holes corresponding to the first set of adjustment holes in two rows. The pivoting seat has a pivoting hole. Each of the supports is fixed onto the base plate by fastening bolts passing through the fixing holes and selective two of the first set of adjustment holes. The clipless pedals are separately screwed into the pivoting holes.

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.
