Abstract

An exercise machine includes a horizontal base portion, a first vertical post, a mechanical load system having a horizontal pivot arm arranged on second vertical post, a pivotable post, a seat, a footplate, and a kneepad assembly. The first vertical post, the second vertical post, and the pivotable post are affixed to the horizontal base portion; the seat is affixed to the second vertical post; and the footplate and the kneepad assembly are affixed to the pivotable post. The pivotable post is arranged to position the kneepad assembly in relation to the seat. The horizontal pivot arm is adjustable relative to the seat, including s first position being proximal to a lumbar region of a user, and a second position proximal to a cervical region of the user. The mechanical load system is controllable to urge a mechanical resistance to a force being exerted on the horizontal pivot arm.
