A drive system for a magnetic resistance exerciser includes a fixed wheel and at least one rotatable wheel which are rotatably connected to the weight wheel and the fixed wheel by two respective belts. The fixed wheel and the weight wheel share a common shaft which is perpendicularly connected with a link and the at least one rotatable wheel is rotatably connected to an extension on an end of the link. When rotating the shaft, the link rotates and the at least one rotatable wheel rotates about the shaft and the extension simultaneously so that the rotational speed of the weight wheel can be increased without increasing the whole system.
