US Patent 7717828 Exercise device with pivoting assembly

A non-impact exercise device comprising a framework, resistance assembly, and a pivoting assembly. The pivoting assembly contains a pair of link arms pivotally coupled to a pair of foot support members. The link arms have handles for the user to grip and the foot support members have foot platforms for the user to stand upon. The foot platforms have a wheel attached to them and the wheel rests upon curved or arced ramps of the exercise device. The user exercises by putting force into the device through the handles and/or foot platforms. This causes the foot platforms to roll along the ramps while the user is standing upon the foot platforms. The user may readily vary the length and frequency of the reciprocating stride.
