Abstract
A manually powered elliptical motion exercise apparatus includes a floor-supported frame, a crank mechanism defining a first axis, and radially-extending crank arms. A pair of elongated pedals include foot-receiving platforms for supporting a user standing thereon and are coupled to the crank mechanism by crank coupling structures such that each crank coupling structure traverses a generally circular path about the first axis as the pedals are manually operated by a standing user. A pedal guide defines a second axis that is fixed with respect to the frame, and each pedal is constructed and arranged to be supported on the guide for pivoting movement with respect to the second axis and to accommodate a horizontal extent of movement imparted to the foot-receiving platforms by movement of the elongated pedals around the first axis so that the foot-receiving platforms traverse an elliptical path of motion simulating natural striding foot movements. The apparatus includes hand-grasping structure to be grasped by the hands of user standing on the foot-receiving platforms. The apparatus further includes a pedal movement resisting mechanism operatively connected with the crank axle and incl…
