Patent ID: 7156786

Claim:
An exercising device upon which one kneels and can exercise one's thighs and buttocks by pushing one's knees away from each other in a direction substantially parallel with a line through one's hip joints, said device comprising: a. a pair of longitudinal swing arms having respective first and second ends; b. a pair of upwardly extending, spaced apart pivot axes; c. means for pivotally mounting each of said first ends of said swing arms to respective pivot axes so that the swing arms extend generally laterally outwardly from the respective pivot axes and can pivot about said respective pivot axes from a first position in which said swing arms are substantially parallel with each other to a second position in which said second ends of said swing arms diverge outwardly from each other so that said swing arms form an acute angle with each other; and d. a pair of elongate leg support members, each leg support member having two substantially parallel elongate edges and being mounted on a respective longitudinal swing arm in a manner rigidly fixed with respect to said respective longitudinal swing arm, said elongate leg support members having a curved upper surface, the curved upper surface defining curved sides and an axis substantially parallel to the elongate edges, thereby forming a smooth, elongate trough in which shins of the user are received; wherein, the knees of a user of the machine are accommodated in a position adjacent respective second ends of said swing arms, with the shins of the user lying adjacent respective swing arms so that the user can kneel on said leg support members and can move the user's knees in reciprocating motion away from and back toward each other in a direction such that a line through the knees of the user is substantially parallel with a line through the hip joints of the user.
