The invention is an exercise apparatus providing an advanced level of surfboard paddling simulation and muscle development. The design includes a specialized platform, unique hand harnesses, and cable systems with mechanical advantage and mass moment of inertia mechanisms, piston pumps, cable spools, and elastic elements. They allow the user to simulate paddling in an alternating or simultaneous sequence at any speed while strong elastic tension resists the user's thrust strokes, but during paddling return strokes the user feels no elastic tension or resistance. The design also prompts the user to engage and strengthen all dorsal muscles to maintain an appropriately arched body position while paddling.

A multifunctional treadmill is provided with a platform on the running deck. A reception cavity is formed on a top of the platform, the reception cavity has a sensor and an operating board tiltably mounted on one side of the reception cavity. When the operating board is released for the reception cavity, the treadmill is in a standard speed mode. When the user wants to exercise and work or do other activities at the same time, the user can store the operating board into the reception cavity so that the operating board and a top surface of the platform become a workbench. Simultaneously, the sensor is triggered and the treadmill changes to a low speed mode. Thus, the safety may be improved by forcefully restricting the speed of the running deck.

A stationary exercise equipment has a supporting structure, a movable user interface connected to the supporting structure, and a force-resisting device. The force-resisting device with a hub mounted continuously variable transmission configured therein provides a variable resistance force that varies an amount of force with a movement of the movable user interface. The hub mounted variable transmission is operably to vary the resistance force of the movable user interface in a manner of varying a rotational rate of the user interface to increase or decrease as required.

A knee rehabilitative device permits a user to provide resistive stretching caused when the leg or other joint is extended or straightened, facilitating exercise and strengthening of the user's muscles and improved flexibility in the area of the knee or other joint area.

An exercise support machine configured to support at least a portion of a user's weight is provided. The exercise support machine can include a frame portion having a plurality of frame members defining an interior region of the machine. The machine can further include two vertical support members extending upward from the frame portion and a lever arm pivotally connected to the upper ends of the vertical support members. The lever arm can include a seat connected to a first end of the lever arm and positioned within the interior region of the machine. The machine can further include a lifting mechanism connected to the frame portion and the second end of the lever arm. The lifting mechanism can control the vertical movement of the seat to provide weight bearing support for the user of the machine.

The gyroscopic exercise device, comprised of one or more rotating mass equipped with accompanying gears, bearings, and optional components, encased in a frame connected to an attachment which contains additional optional equipment including electric motors, magnets, batteries, wiring and electronics, to which one or more handles or grips are connected in a temporary or fixed position, intended to overcome the high degree of difficulty and failure new users experience when using prior art friction-based gyroscopic exercise devices, by providing a novel driving system and rotor that is substantially more efficiency, powerful and durable with means of servicing wear points, enables users to consistently progress, further encouraging regular use, thereby developing greater strength circulation, and coordination in the hands, arms and upper body, which enhances stability and control when users operate handheld equipment.

Gait tread simulation fitness equipment is provided, which utilizes a multi-linkage mechanism disposed on a main body and a suspending side frame to make an action track of a pedal to match the natural gait tread well. In addition, the relative position of the movable pivot can be adjusted to obtain different exercise modes for training different muscle groups, so as to achieve the objective of exercise training.
