Since each of the resistance transmission sets 262 is linked with the driving axle 261 and the driving wheel 2502 of the linkage member 250 via the one-way bearing 2623, the linkage member 250 can be driven along the same direction during the two operating members are linked up with and reversely reciprocated to each other. Then, the magnetic resistance set 240 can be driven to rotate along the same direction.

Moreover, the linkage member 250 can further includes a belt tensioning set 251 which is disposed on the main frame 210 and elastically abutted against the belt 2501.

wherein the linkage member is connected to one of the two ends of the driving axle and one of the one-way bearing, so that the linkage member drives the magnetic resistance set to generate the resistance by the resistance transmission set during the pivoting member which is coaxially connected to the coaxial unit of the resistance transmission set is driven by one of the two operating members.

18. The exercise apparatus of claim 17, wherein the linkage member comprises a belt and a driving wheel, wherein the driving wheel is connected to the end of the driving axle, and the belt connects the driving wheel and the magnetic resistance set.

19. The exercise apparatus of claim 18, wherein the linkage member further comprises:

a belt tensioning set disposed on the main frame and elastically abutted against the belt.

20. The exercise apparatus of claim 19, wherein the belt tensioning set comprises:

a base member;

a pivoting axial unit pivotally connecting the base member to the main frame;

a tensioning wheel connected to one end of the base member and abutted against the belt; and

a spring, one end of the spring is connected to the other end of the base member, the other end of the spring is connected to the main frame.
