An exercise machine includes a cyclical actuator and a mechanical energy storage device. Connective structure operatively connects the cyclical actuator to the mechanical energy storage device. Motion of the cyclical actuator urges physical motion of and energy storage in the mechanical energy storage device. The exercise machine further includes an electric machine. A communication pathway enables exchange of data between multiple associated exercise machines such that multiple associated operators on multiple associated exercise machines have a common experience.

A multifunctional cardiovascular exercise machine may include a frame including a first and second end attached to one another by a pair of ski rails and a centrally located center frame rail. A flywheel may be operatively mounted to the frame, and a pulley system may be mounted to the frame, the pulley system supporting and routing a pull rope, wherein the pull rope is operatively engaged with the flywheel, and a free end of the pull rope is removably engaged with a pull bar, a pair of ski poles, and/or a pair of pull handles. A sliding seat may be operatively attached to the flywheel and slidably mounted to the center frame rail, and a pair of footrests may be mounted to the frame proximate to the flywheel.

A rowing machine includes a base mount with pulleys, a resistance device, a handle, a transmission member, and a resilient member. The resistance device includes a housing, a shaft having an outer shaft section located outside the housing, and an inner shaft section located inside the housing, a plurality of blades mounted to the inner shaft section, and a transmission wheel mounted to the outer shaft section. The transmission member extends from the handle and has an engagement section engaged with the transmission wheel. The resilient member has a first end disposed to the based mount, and a second end connected with the transmission member in a way that the transmission member and the resilient member wrap around the pulleys. As such, the rowing machine can provide uniform resistance and accurately determine the travel distance of the handle that is pulled by a user.

A realistic sloping simulation device for a fitness equipment is disclosed, generally including a fixed base, a host tube, a support frame, and a driving unit. The host tube has a first end coupled to the fixed base. The support frame has a lower end slidably coupled to the fixed base and an upper end pivoted to the host tube between the first end and the second end. The driving unit is disposed between the host tube and the support frame or between the host tube and the fixed base. The fixed base, the host tube, and the support frame jointly form a linkage mechanism. By means of the driving unit driving the lower end of the support frame to move relative to the fixed base or the host tube, the second end of the host tube is caused to swing or rotate so as to simulate different slopes.

An exercise machine has a base housing and a boom that extends from a proximal end to a distal end. The boom is able to pivot between a rowing configuration wherein the boom is generally horizontal, and a skiing configuration wherein the boom is generally vertical. A rowing assembly includes a row handle attached to a row chain which extends into the base housing, to a row recoil device. A ski assembly includes a pair of ski handles, each ski handle being attached to a ski rope which extends into the base housing, to a ski recoil device. A transmission system has a shaft that is operably connected to a resistance device, the shaft having a row sprocket and a pair of ski spools, and the respective cables contact the spools so that movement of one of the cables rotates the respective spool, thereby rotating the shaft.

A rowing machine convertible for use both indoors and outdoors. In the outdoor mode, the rowing machine is configured for adaptation to a watercraft, such as a kayak or stand up paddle board (SUP). A rower operating the rowing machine pulls on a rope or cord to cause paddles positioned at the rearward end of the machine to rotate and move the machine on a body of water. In the indoor mode, legs are attached to the machine for placement on a rigid surface. The paddles are placed in a container holding fluid.

An exercise machine includes a cyclical actuator and a mechanical energy storage device. Connective structure operatively connects the cyclical actuator to the mechanical energy storage device. Motion of the cyclical actuator urges physical motion of and energy storage in the mechanical energy storage device. The exercise machine further includes an electric machine. A communication pathway enables exchange of data between multiple associated exercise machines such that multiple associated operators on multiple associated exercise machines have a common experience.

A resistance system for a rowing machine has a mounting bracket, and a housing assembly, a driving assembly and a restoring assembly mounted on the mounting bracket. The housing assembly is for storing liquid and a paddle wheel. 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 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 dynamic rowing machine configured to simulate the motion of a rower working through the rowing motion of a rowing scull is provided. The dynamic rowing machine includes a stationary framework having one or more lifting profiles. Each of the lifting profiles has one or more segments forming a rising path and one or more segments forming a horizontally rearward path. The one or more segments forming a rising path and the one or more segments forming horizontally rearward path form a continuous path. A dynamic framework is supported for movement along the continuous paths of the one or more lifting profiles of the stationary framework. Movement of the dynamic framework along the continuous paths of the one or more lifting profiles of the stationary framework results in upward and rearward movement of the dynamic framework.
