There is described a parallel bar exerciser suitable for simulating a horizontal ladder comprising a plurality of hand-bars; each hand bar being linked to a drive member said drive member being operably linked to a drive means.

An exercise machine is disclosed. The exercise machine comprises a pancake motor. The exercise machine comprises a torque controller coupled to the pancake motor. The exercise machine comprises a high resolution encoder coupled to the pancake motor.

A treadmill is provided. A rotation device rotatably supporting a track unit of the treadmill includes a pair of bearing trains rotatably installed at a frame structure and including a plurality of first bearings arranged along a movement direction of a belt to guide a movement of an upper region of a pair of belts and a front rotation module and a rear rotation module rotatably installed at the frame structure and respectively arranged at a front side and a rear side of the pair of bearing trains. At least one of the front rotation module and the rear rotation module includes a pair of rotation members arranged spaced apart from each other in a direction perpendicular to a rotation direction thereof and a pair of rotation support units supporting the pair of rotation members such that the pair of rotation members rotate individually.

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.

A weight lifting device including a housing having first frame having first vertical channel for accommodating first weight holding means and second frame having second vertical channel for accommodating second weight holding means, wherein first vertical channel and second vertical channel are dimensioned so that first weight holding means and second weight holding means can move up and down, when in use, in first vertical channel and second vertical channel, respectively. The weight lifting device also includes a handle bar pivotably connectable to first weight holding means and to second weight holding means from first end of handle bar and second end of handle bar, respectively. The weight lifting device further includes at least one of: first holding bar, second holding bar, first pivotable arm and second pivotable arm, arranged between pivotably connectable handle bar and first weight holding means and second weight holding means.

The present invention provides a manual treadmill, the manual treadmill includes a frame having a front support portion and a rear support portion, a running belt disposed about and supported by the front support portion and the rear support portion, and a speed limiting device, wherein the running belt rotates in a first rotating direction or a second rotating direction in response to a directional movement of a user. The speed limiting device includes a one-way bearing, a rotating element and a transmission element, wherein the rotating element is coupled to the front support portion, and the one-way bearing is connected to the rotating element via the transmission element to limit a speed of the running belt in the second rotating direction.
