A resistance system for a rowing machine has a mounting bracket, a housing assembly, a paddle wheel, a driving assembly and a restoring assembly. The housing assembly is mounted on the mounting bracket and includes a liquid tank for storing liquid. The driving assembly is connected to the paddle wheel and drives the paddle wheel to rotate in a direction only. The restoring assembly is connected to a strip hub of the driving assembly and is able to drive the strip hub to rotate in a reverse direction. The resistance system for the rowing machine has simplified structure. Therefore, it is easy to assemble to the resistance system, and manufacturing cost of the resistance system can be decreased. In addition, a service life of the resistance system as well as the rowing machine can be increased.

A rowing machine to simulate the action of rowing a watercraft includes an energy damper, a handle, and a tensile member connecting the handle to the energy damper. The handle includes a grip member with a right hand grip and a left hand grip, and a connecting member connected to the tensile member. The connecting member is configured to transmit a force from the tensile member to the handle such that the force is substantially centered between the left hand grip and the right hand grip. The grip member is configured to rotate relative to the connecting member and provide at least one of a haptic indication and an audible indication when the grip member rotates relative to the connecting member from a first position to a second position that is substantially ninety degrees from the first position. The simulation may include actions to replicate feathering an oar.

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.

An assembly is provided for incorporating a media playback device remote control into a rowing machine handle, without requiring modification to the handle itself. The user interface on the remote control is configured to enable a user to readily access the controls while using the machine, substantially without interfering with the user's grip on the handle. Moreover, the remote control employs wireless communication to interface with a host media playback device, which in one embodiment, can provide the user real-time data regarding the quality of handle motion.

Described herein are various embodiments of differential air pressure systems and methods of using such systems. The differential air pressure system may comprise a chamber configured to receive a portion of a user's lower body and to create an air pressure differential upon the user's body. The differential air pressure system may further comprise a user seal that seal the pressure chamber to the user's body. The height of the user seal may be adjusted to accommodate users with various body heights.

A joint extension system that embodies a method of exercise that applies progressive accommodating resistance to joint extension during closed-chain movement.

A computer-implemented system may include a rowing machine configured to be manipulated by a user while the user performs a treatment plan, an interface comprising a display configured to present information associated with the treatment plan, and a processing device configured to receive, from one or more data sources, information associated with the user, wherein the information comprises one or more risk factors associated with a cardiac-related event; generate, using one or more trained machine learning models, the treatment plan for the user, wherein the treatment plan is generated based on the information associated with the user, and the treatment plan comprises one or more exercises associated with managing the one or more risk factors in order to reduce a probability that a cardiac intervention will occur; and transmit the treatment plan to cause the rowing machine to implement the one or more exercises.

Among other things, a rowing technology includes a first rowing machine having an electromagnetic brake providing a resistance to a rower of the machine in each rowing stroke of a series of rowing strokes of the rower An electronic controller causes the resistance of the electromagnetic brake to vary over each rowing stroke in a profile that emulates resistance to which another rower in a shell on water or on a second rowing machine is subjected in each rowing stroke of a corresponding series of rowing strokes.

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 computer-implemented system for an exercise machine includes a mechanical energy storage device and an apparatus configured to supplement the resistance of the mechanical energy storage device with an added resistance and dissipate the energy of the mechanical energy storage device and an associated athlete. A communication pathway enables the exercise machine to communicate with at least one additional associated exercise machine to duplicate the total resistance in the exercise machine to an associated exercise machine. A central server includes a processor, memory, and a networking interface. A first user device includes a display, a processor, a memory, and a networking interface. The central server receives data from the exercise machine, extracts synchronization performance information from the data, and transmits the synchronization performance data to the first user device where it is used to train an athlete for an athletic endeavor.
