A method is disclosed for using an artificial intelligence engine to modify resistance of pedals of an exercise device. The method includes generating, by the artificial intelligence engine, a machine learning model trained to receive measurements as input, and outputting, based on the measurements, a control instruction that causes the exercise device to modify, independently from each other, the resistance of the pedals. While a user performs an exercise using the exercise device, the method includes receiving the measurements from sensors associated with the pedals. The method includes determining, based on the measurements, a quantifiable or qualitative modification to the resistance provided by a pedal of the pedals. The resistance provided by another pedal of the pedals is not modified. The method includes transmitting the control instruction to the exercise device to cause the resistance provided by the pedal to be modified.

An upper body support assembly for use with an associated railed device having first and second rails is disclosed. The assembly includes first and second upper body supports capable of moving along the first and second rails, respectively. The upper body supports have at least one of: (i) first and second forearm supports, (ii) first and second hand grips, or (iii) a first forearm support and a first hand grip. An interconnecting member extends between and selectively connects both the first and second upper body supports to permit (i) interrelated movement therebetween when connected, and (ii) independent movement therebetween when disconnected. The assembly can achieve two point gait, three point gait, and four point gait movement.

An exercise device for use by persons with limited strength or mobility includes a a frame member situated in an interior area of a body member. First and second upper appendages are coupled to and extend away from upper left right regions of the body member. First and second lower appendages are coupled to and extend away from lower left right regions of the body member. A top appendage may extend away from a top region of the body member. A tension member, such as a tension spring, is situated inside each appendage and is configured to be selectively bent, extended, or otherwise manipulated and is resilient to return to an unbent and retracted configuration. Movement of respective tension members enables a person to exercise, experience the touch sensation, and have feelings of pleasure and enjoyment. A magnet attached to the frame member attracts other magnetic or metal items.

A rowing simulation trainer includes a base frame, a pulling unit, an inertia wheel unit and a guiding unit. The pulling unit includes a shaft, a first belt wheel, two cord wheels, two pulling cords, two handgrips and two elastic coiled plates. The guiding unit includes two mounting tubes. Each of the two pulling cords extends through one of the two mounting tubes. Thus, the two cord wheels and the two pulling cords cooperate to drive the inertia wheel unit and are respectively operated independently without interfering with each other. In addition, the two pulling cords are limited by the two mounting tubes so that the two pulling cords are kept in line with and will not be deflected from the two cord wheels.

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 symmetric upright rotating disc exercise machine includes a base unit and two upright rotating disc units. Each upright rotating disc unit includes a rotating shaft, an upright disc, and a grip. The rotating shaft is pivotally connected to the base unit in a horizontal direction. The upright disc is mounted to the rotating shaft. The upright discs of the two upright rotating disc units are arranged to face each other. The two upright rotating disc units are separated from each other by a distance in the horizontal direction to form an operation space. The grip is mounted to the upright disc and located in the operation space.

A portable exercise device provided includes: a base disc, two pulley assemblies, a support plate, and a fan wheel assembly. A support plate is disposed on the base disc, the two pulley assemblies are provided on the base disc, and the fan wheel assembly is provided on the support plate, so that the fan wheel assembly and the two pulley assemblies are vertically arranged on top of each other, thereby reducing the overall volume. More preferably, because the volume is reduced, the user can arbitrarily move and hang the portable exercise device at the desired position, and because the portable exercise device of the invention can be hung at different positions, which allows the user to train different muscles according to the different positions.

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 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 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.
