Patent ID: 7959544

Claim:
An exercise device for exercising lower limb muscles, comprising: a base configured to support the exercise device; a substantially horizontal arcuate path attached to the base; a plurality of limb supports which rotate circularly along the substantially horizontal arcuate path upon pivot axes on the base; and a pulley comprising: an elastic member, removably and directly attached at a first end to a first connection point on a first side of one of the limb supports and further comprising a second end removably attached to a second connection point proximate to a second side of the one of the limb supports, configured to provide elasticated resistance against movement of the limb support along the substantially horizontal arcuate path; and a sheave, coupled to the base, around which the elastic member at least partially extends; wherein a direction of elasticated resistance is changed when the first end of the elastic member is detached from the first connection point on the first side of the one of the limb supports and is attached proximate to the first side and the second end of the elastic member is directly attached to a third connection point on the second side of the one of the limb supports.
