Abstract: A water-resistance rowing machine has a frame body, a water-resistance unit, at least one blade wheel, a pulling strap, and a seat. The frame body has an elongated beam and a pulley rotatably mounted on the frame body. The water-resistance unit has a water tank extending along the elongated beam, a rotating shaft disposed in the water tank and extending along and being parallel to the elongated beam, and a strap wheel assembly connected with the rotating shaft to drive the rotating shaft to spin. The at least one blade wheel is mounted on and rotated with the rotating shaft. The pulling strap is wrapped around the pulley and has an end connected with the strap wheel assembly and a handle formed on another end of the pulling strap. The seat is mounted on the elongated beam.

Abstract: A heel-lifting elliptical machine has a foundation, two linkage assemblies and two pedal assemblies. The foundation comprises a swing shaft and a driving wheel connected with a flywheel via a driving belt. The linkage assemblies are mounted on two sides of the foundation, staggered from each other, and joined to a driving shaft of the driving wheel. Each of the linkage assemblies comprises a rotation rod, a crank and a swing arm. The rotation rod is connected to the driving shaft. The crank is pivotably mounted on the other end of the rotation rod. The swing arm is pivotably mounted on the swing shaft and the crank. Two pedal assemblies are mounted securely on the cranks and form vertical ellipse routes along with the movement of the cranks, thereby increasing the exercise intensity and decreasing the obstruction and the noise.

Abstract: The adjustable elliptical trainer has a base, a transmitting wheel, two link assemblies and two pedals. The base has a wheel frame mounted on the base and having a fulcrum shaft on a top end of the wheel frame. The transmitting wheel is mounted rotatably on the wheel frame and has a transmitting shaft and two transmitting levers. The transmitting levers are respectively mounted radially on the transmitting shaft and extend in two opposite directions. The link assemblies are respectively set on two sides of the base, and each has multiple levers and an adjusting element. The levers are mounted pivotally on the fulcrum shaft and the transmitting lever to rotate the transmitting wheel. The adjusting element is mounted on the levers and is adjusted to change an orbit of the elliptical trainer. The pedals are respectively mounted on the link assemblies.

Abstract: A foldable step exerciser has a base and two pedal members symmetrically provided on two sides of the base. An interlock member is moveably connected to the base and a stopping element is mounted in a rear end of the interlock member and can slide along the base. A protrusion is mounted in a front end of the interlock member and two driving members are respectively mounted between each pedal and an end of the protrusion. When one of the pedals is treaded downwards, the other pedal is moved upwards via the protrusion being driven by the driving members and therefore, a user can exercise. When the interlock member as well as the stopping element is adjusted to move forwards and the pedals are not limited by the stopping element, the pedals can be folded for convenient storage.
