An embodiment of the present invention provides an elliptical trainer including structures featuring a first amplitude, a second amplitude, and a third amplitude. By the driving of cranks and the combination of the three amplitudes, the elliptical trainer's pedals move along a closed ellipse path. In addition, the first amplitude is more than twice or three times of the third amplitude, resulting in a wide adjustment range of the stride of the pedal. Accordingly, the elliptical trainer is applicable to users of various heights.

Embodiments of the present invention disclose an exercise machine including a supporting mechanism, two driving units, and a resistance device. The supporting mechanism supports the two driving units and the resistance device. The two driving units are respectively mounted at the left and the right side of the supporting mechanism for the user to operate. When the exercise machine is operated with a 'small pace,' the resistance device is operated in both directions to eliminate the blockage when switching the operating direction of the driving units. When the exercise machine is operated with a 'large pace,' the resistance device can provide resistance for the driving units in either direction.

An integrated flywheel set for exercise equipment includes a base plate, a flywheel that is coaxial with the base plate and arranged such that an accommodating space is formed between the flywheel and the base plate, a magnetic damper unit that is deposited on the base plate and received in the accommodating space and provides magnetic attraction to hinder the flywheel from rotation, and a transmission that is received in the accommodating space and configured to drive the flywheel to perform an inertial motion. Thereby, the integrated flywheel set has the magnetic damper unit, a driving wheel set, a driven wheel set, and a multiplying wheel set integrated on the base plate, allowing exercise equipment to have its internal space used more effectively, and making the production and maintenance of the integrated flywheel set easier, thereby providing economical advantage.

An elliptical trainer with a variable track is disclosed. The elliptical trainer has a base, a left and a right linkage, a transmission and a left and a right adjusting assembly. The linkages are connected to an upright posts extending upward from the base, respectively. Each of the linkages includes a pedal set configured to slide with respect to the linkage. The transmission deposited on the upright post drives the pedal sets to perform reciprocal elliptical motions. The adjusting assemblies are pivotally connected to the upright post, respectively, and serve to change an elliptical track along which the pedals move. Thereby, the elliptical track varies by expanding or retracting along only a major axis thereof. When using the elliptical trainer, a user will not need to step higher as the elliptical track expands. This design is more ergonomic and adaptive to users with various body heights and habitus.

A pedal motion path adjustable elliptical trainer includes a base frame, a rotating mechanism assembly, a lifting mechanism, a sliding mechanism and a control mechanism. The lifting mechanism is biasable relative to the base frame, including a rail holder, a support member and two sliding rails. The rotating mechanism assembly includes two cranks coaxially pivoted with one of each of the ends thereof to the base frame, and a support link set pivotally coupled between the other ends of the cranks and slidably coupled to the sliding rails. The control mechanism is mounted between the base frame and the rail holder to control the angle of deflection of the lifting mechanism. The sliding mechanism is pivotally coupled between the control mechanism and the rail holder. Thus, the invention allows quick adjustment of the pedal motion paths, training different muscles of the legs.
