ABSTRACT:
A mountain climbing training machine includes a conveyor belt with a number of shell plates fastened onto the conveyor belt. The shell plates have associated irregular contours defined by rock-like protrusions. The shell plates are secured at spaced locations along the rotating conveyor belt. The shell plates provide a treading surface while the conveyor belt rotates. As arranged, the shell plates go around the semi-circular surfaces of revolving shafts at both ends of the conveyor belt without producing a build-up of resistance in the process.
