By repeatedly stepping on the pedals 5 in the above steps, the climbing resistance can be increased to achieve a better training effect. In addition, the grips 5 or the armrests 8 held by the user's hands are also moved up and down in synchronization with the action of the pedals being stepped on the pedals 5. Therefore, the embodiment can also simulate climbing. When the hands and feet are synchronized, the training effect is better.

A resistance band 712 of the 751 is used to frictionally contact the rotor 711 and produces the second frictional resistance. The resistance band 712 has a first end 7122 coupled to the brake 751. The rotating units 72 are disposed on two sides of the rotating wheel 711 , and each rotating unit 72 includes the one-way rotating member 721 disposed on the rotating wheel 711 . The driving mechanism 73 is bidirectionally coupled and connected to the rotating unit 72 and the pedals 5 respectively. When one of the pedals 5 is lowered, the corresponding one-way rotating member 721 is rotated and the rotating wheel 711 is rotated. The first damper unit 75 is caused to frictionally rotate the wheel 711 to generate the first frictional resistance.
