## Abstract

An exercise device includes two cranks rotatably coupled to a rear portion of a upright support and each having a pivot rod, two handles having a middle portion pivoted to a front portion of the upright support with a spindle, two foot supports pivotally coupled to the handles and each having a middle portion pivotally coupled to the pivot rod of the cranks with a link, the front portions of the foot supports may be controlled by the handles to allow the foot supports to be actuated as a stepping exerciser when the front portions of the foot supports are stably held in place by the handles, and to allow the foot supports to be actuated as an elliptical exerciser when the handles are swung by the user.

## Claims

### Claim 1

An exercise device comprising:
a base including an upright support extended upwardly from said base and including a front portion and a rear portion,
a spindle disposed on said front portion of said upright support,
two first cranks rotatably coupled to said rear portion of said upright support with a shaft, said spindle being spaced from said shaft and located in front of said shaft and said first cranks, said first cranks each including a pivot rod attached to said first crank and spaced away from said shaft,
a wheel rotatably attached to said rear portion of said upright support with said shaft,
a rotary member rotatably attached to said uptight support with an axle and coupled to said wheel,
a flywheel rotatably attached to said upright support with a pivot rod and coupled to said rotary member for resisting a rotational movement of said shaft and said first cranks,
a pivot pole disposed on said upright support,
two handles including a middle portion attached to said spindle for allowing said handles to be pivotally coupled to said front portion of said upright support with said spindle and for allowing said handles to be pivoted and swung relative to said upright support of said base, said handles each including a hand grip provided on an upper portion for being grasped or held by a user and each including a lower portion,
two foot supports each including a front portion pivotally coupled to said lower portion of said handles, and each including a foot pedal disposed on a rear portion for supporting said user's feet, and each including a middle portion pivotally coupled to said pivot rod of said first cranks with a link for allowing said middle portions of said foot supports to be moved cyclically relative to said upright support of said base by said first cranks,
said front portions of said foot supports being controlled by said handles to allow said foot supports to be actuated as a stepping exerciser when said handles and said front portions of said foot supports are stably held in place by the user with said hand grips, and to allow said foot supports to be actuated as an elliptical exerciser when said handles and said front portions of said foot supports are moved or swung by the user, wherein said stepping exerciser provides a primarily vertical stride to said pedals and said elliptical exerciser provides an elliptical stride to said pedals, and
two second cranks coupled together to said pivot pole and coupled to said handles respectively for coupling said handles together.
