Patent ID: 7591766

Claim:
An exercise device providing both extension and flexion resistance forces to seat travel motion relative to a front cross member, said exercise device comprising: a main beam, said main beam having a seat slidably engaged to said main beam, said seat having a seat pan, said seat able to slide along said main beam along a seat travel axis, said seat having a seat pan axis substantially perpendicular to said seat pan, said main beam having a first end and a second end; a front cross member, said front cross member engaged to said main beam at said first main beam end; first and second foot rests engaged to said front cross member; a seat extension resistance device engaged to said seat such that motion of said seat away from said first end is impeded by resistance imposed by said seat extension resistance device; and a seat flexion resistance device engaged to said seat such that motion of said seat towards said first end is impeded by said seat flexion resistance device; wherein said seat is rotatable around a pitch axis perpendicular to said seat travel axis; wherein said seat rotates about said pitch axis to reduce the acute angle between said seat pan axis and said seat travel axis when said seat traverses towards said first end; and wherein said seat rotates about said pitch axis to increase the acute angle between the seat pan axis and the seat travel axis when said seat traverses away from said front cross member.
