Abstract: A positioning device for a portable fitness equipment mainly provides a support frame for hanging the portable fitness equipment. The support frame includes a base and a support rod connected to each other, and there is an obtuse angle between the base and the support rod. The obtuse angle design allows the position where the support rod is connected to the base to bear less torque, which can effectively prevent the support rod from shaking or damage; and the portable fitness equipment can slide or can be fixed on the support rod, allowing users to adjust the portable fitness equipment to the most suitable height.

Abstract: An improved magnetoresistance adjustment device of fitness equipment suitable for using in a fan-type fitness equipment. The fitness equipment having a traction rope, and including: a resistance wheel mounted on the fitness equipment and having a wheel and an axle, the axle being mounted on the wheel; a magnetoresistive ring mounted on the resistance wheel; a fixing member fixedly mounted on the axle and having a positioning bolt, a direction of the fixing member extending to the magnetoresistive ring being a displacement direction; a displacement member having a displacement hole, a fixing portion and a magnetoresistive portion, the displacement hole allowing the positioning bolt to pass through, and the displacement member repeatedly displacing along the displacement direction to bring the magnetoresistive portion closer to or away from the magnetoresistive ring, and the fixing portion being connected to the traction rope and driven by the traction rope.

Abstract: A multi-axial unidirectional power transmission system includes a transmission unit and a resistance unit. The transmission unit includes a first main shaft and a transmission wheel provided on the first main shaft. The resistance unit includes a second main shaft and a damping wheel mounted on the second main shaft. The two transmission wheels and the damping wheel can be placed flat on the body since they are mounted on different main shafts, thereby making the whole plane of the multi-axis unidirectional power transmission system consistent, thus achieving the effects of space saving, convenient storage and convenient transportation.

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.

Abstract: A rowing exercise machine comprises a base, a first swinging member, a second swinging member, a seat tube, a seat, a third swinging member, a first pulley, a second pulley, a pull cable, a hand grip, and two pedals. A rowing exercise is brought about by a person sitting on the seat of the rowing exercise machine, with the person's feet pedaling the pedals and the person's hands holding the hand grip to pull rearwards the pull cable to cause the first swinging member and the third swinging member to move closer so as to actuate the seat tube to move upwards and rearwards. As the pull cable is relieved of the pressure exerting thereon, the seat tube is caused by the person's weight to move forwards and downwards so as to actuate the first swinging member and the third swinging member to move away from each other in opposite directions.
