Exercise Apparatus with Divergent/Convergent Motion Along the Symmetric Semi Elliptical Rout

Abstract

An exercise apparatus with divergent/convergent motion along the symmetric semi elliptical route includes a base frame for supporting all the components of the apparatus, two handlebars move along the symmetric semi elliptical route, two feet pedals move along the symmetric semi elliptical route in harmony with the handlebars, Two link mechanisms to create symmetrical semi elliptical route to support handlebars and feet pedals, power transmission system to connect link mechanisms and synchronize their motion. This apparatus enables user to move hands forward/backward in the same direction so that hands have a lateral divergent motion at the start of the route and lateral convergent motion at the end of the route. By moving hands along the symmetric semi elliptical route a symmetrical variable pressure will be applied on the different muscles. Feet move along the symmetric semi elliptical route in full harmony with hands so that hands move backward/forward in the opposite direction of feet.
