The present invention relates to the field of fitness training devices and exercise machines. More specifically, a substantially horizontal exercise machine comprising an exercise platform slidable along one or more rails aligned with the longitudinal axis of the machine structure, the slidable platform spring-biased towards one end of the machine, is tiltable to allow for one end of the machine to be raised or lowered relative to the opposed end of the machine.

An exercise bike includes a frame, a rotor assembly and a drive assembly mounted on the frame, where the drive assembly is configured to drive rotation of the rotor assembly, and a cover configured to at least partially cover the rotor assembly. The components of the drive assembly and the rotor assembly include structures that improve the performance of the exercise bike, including but not limited to a strong and rigid construction and improvements in belt tracking, user feel, effort consistency, synchronization, and rotor performance.

An exercise machine creates a simulated continuous resisted climbing motion. The machine includes a floor- or ground-contacting base frame and two or more substantially vertically oriented uprights, wherein at least one upright is rigidly connected to the base frame. The machine further includes two handles and two foot pedals, each handle and each foot pedal being movably engaged with an upright for linear reciprocating motion along the upright. The handles and foot pedals are interconnected so that they move in unison. An adjustable resistance mechanism is operatively connected to the interconnection of the handles and foot pedals to provide adjustable resistance for the simulated continuous climbing motion.

An elliptical machine has a base, an upright column fixed to the base, a transmission mechanism mounted on the base, and two link mechanisms respectively connected with opposing sides of the transmission mechanism. Each link mechanism includes a first link rod that is telescopic and connected with both the transmission mechanism and the base, and a second link rod having a pedal and connected with the first link rod such that the pedals of the two link mechanisms are respectively linked to the transmission mechanism through the first and second link rods. When a user uses each pedal, a total length of the corresponding first link rod is reciprocatingly and continuously changed, so that a top end of the first link rod makes a first circulatory movement along a first elliptical path, and the corresponding pedal synchronously makes a second circulatory movement along a second elliptical path.

An elliptical machine includes a machine frame and two pedal units each including a vertical arm having a top end pivotally connected to the machine frame and swingable back and forth, a driving main arm having a front end arranged on an opposing bottom end of the vertical arm in a vertically swingable manner, a pedal mount arranged on an opposing rear end of the driving main arm and swingable left and right, a pedal arranged on the pedal mount and swingable left and right, a slanting rod having a front end arranged on the vertical arm in a vertically swingable manner and an opposing rear end arranged on the pedal mount in a universally rotatable manner, and a rocking link that has a front end arranged on the rear end of the driving main arm and swingable back and forth and up and down.

A weight bar foot plate device for safely performing leg presses includes a plate and a set of couplers. The couplers, which are coupled to a top of the plate, are configured to couple the plate to a weight bar of a leg press machine so that a bottom of the plate is positioned below the weight bar. The bottom of the plate is configured to position feet of a user who is supinely positioned below the plate, positioning the user to perform a leg press exercise.

A linkage mechanism with handles linked to an elliptical motion trajectory includes a main body having two guiding tracks with a changeable lifting angle, a flywheel assembly and two handles installed on a front side of the main body, a first linkage rod pivotally attached between the two handles and two cranks of the flywheel assembly. The two pedals respectively include a front end, and a second linkage rod is pivotally attached between the front end and each one of the cranks. A third linkage rod is pivotally attached between each one of the pedals and each one of the handles. Each one of the pedals along each one of the guiding tracks, and drives each one of the handles and the flywheel assembly to move.

An exercise machine is for performing a striding exercise motion. The exercise machine has frame; first and second pedal members; first and second foot pads on the first and second pedal members, respectively, each of the first and second foot pads being configured to move in an elliptical path during the striding exercise motion; first and second rocker arms pivotally coupled to the frame; and first and second adjustment devices configured to actively adjust and set a position of the first and second pedal members relative to the first and second rocker arms, respectively, which thereby changes a shape of the elliptical path.

A novel treadmill has a practical hand-powered system to replace the electric motor for driving the tread belt. The hand-powered system includes fixed range movement of both handles, cranks coupling system for two handles, and a cyclic spring or magnetic energy storage and release system to help pass each handle's dead spot. The handles' pivotal and reciprocal movement can be smoothly and efficiently converted to tread belt movement.

Disclosed is a track exercise device including at least two substantially parallel tracks, at least four movable platforms, wherein at least two movable platforms are on a first track, and wherein at least two movable platforms are on a second track. A transverse attachment attaches the movable platforms on adjacent tracks, a longitudinal attachment attaches the movable platforms on the same track, and a tilting adjustment provides for inclined or flat movement.
