A cordless treadmill includes a deck assembly including a frame, a belt system, an incline adjustment system, and a generator system; and a display assembly that supports an electronic display device above the deck assembly for displaying information to a user. The incline adjustment system includes a lever and a lift motor, the lever having a first end rotatably coupled to a frame of the deck assembly. The generator system includes a flywheel generator coupled to at least one of a forward or rear roller and configured to generate electricity as a result of the at least one of the forward or rear rollers rotating with respect to the frame, wherein the flywheel generator is configured to provide power to the electronic display device and the lift motor.

A resistance system, which can be suitable for incorporation in exercise equipment, is a hybrid resistance assembly having at least a first and a second resistance unit. The first resistance unit can be of a first type and the second resistance unit can be of a second type. The first resistance unit can be an inertial resistance unit, which incorporates an inertial load that creates resistance influenced by the inertia of a movable mass, such as a rotatable flywheel. The second resistance unit can be a static or non-inertial resistance unit, such as a displacement resistance unit, which incorporates a load that creates resistance influenced by displacement (e.g., linear or rotational displacement) of an input to the displacement resistance unit.

Controlling an exercise machine includes receiving a stream of measurements of extension of a component of an exercise machine. It further includes detecting a first phase of a repeated motion. It further includes detecting a transition to a second phase of the repeated motion. A time constraint is applied to the detection of the transition to the second phase of the repeated motion. It further includes controlling a resistance associated with the second phase of the repeated motion.

A cable exercise device includes a vertically movable weight stack, a rotatable spool assembly, first and second cables, and a movable exercise implement. The rotatable spool assembly is located proximate the weight stack, and comprises spaced apart large and small cable spools affixed to a common rotatable spool shaft. The first cable has a terminal end attached to the weight stack and a winding end attached to the small cable spool. The second cable has a winding end attached to the large cable spool, and extends from the large cable spool to a terminal end. The movable exercise implement is secured to the cable exercise device by the terminal end of the second cable, and is adapted for being employed by a user performing an exercise.

An exercise bike includes a main frame having a seat extending therefrom. A peddle assembly is mounted on the main frame. A rotating damping element is rotatably mounted on the main frame by a second axle. A drive assembly is connected to the peddle assembly and the second axle. An internal gear device is disposed on the rotating damping element and includes a casing, an internal transmission is centrally received in the casing for driving the casing and a drive element connected to the internal transmission for operating the internal transmission. The second axle centrally extends through the internal gear device and the internal transmission is securely sleeved on the second axle, wherein the rotating damping element is securely sleeved on the on the casing. The damping provided to the exercise bike A is adjusted when the drive element of the internal gear device is operated once.

A cordless treadmill including a frame, a belt system, and a drop-in cartridge is disclosed. The cartridge includes a plurality of staggered rollers configured to provide tactile feedback to the user. The frame is adapted to receive the belt system and the cartridge as they are lowered into the frame, and the frame is adapted to place the belt of the belt system into tension as the belt system is lowered into the frame. An integrated flywheel generator system provides smooth operation of the treadmill and generates electricity to power additional systems.

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.

Disclosed herein are robust disposable alternating tangential flow (ATF) housing and diaphragm pump units and associated methods of manufacturing, testing, wetting, and using the same.

An elastic band for use in a resistance-type exerciser. The elastic band includes a continuous loop of elastic material having a pair of receiving portions and a pair of spanning portions extending between the pair of receiving portions. A cross-sectional area of each receiving portion is greater than a cross-sectional area of each spanning portion.

A personal force-resistance cable exercise device includes a force resistance assembly, elongated flexible cable, and a movable exercise implement. The force resistance assembly comprises a mounting frame, a rotatable assembly shaft carried by the mounting frame, a disk rotor fixedly attached to the assembly shaft, an adjustable friction controller adapted for frictionally engaging the disk rotor, and a one-way cable spool. The one-way cable spool is locked to the assembly shaft upon rotation of the cable spool in a working force-resistance direction, and is freely movable relative to the assembly shaft upon rotation of cable spool in an opposite cable-wind-up direction. The flexible cable is attached to the force resistance assembly, and adapted for winding on and unwinding from the cable spool. The exercise implement is attached to the flexible cable, and adapted for being employed by a user performing an exercise.
