Abstract
Abstract A low row exercise machine includes a frame, a seat and chest support connected to the frame along a vertical midplane, and a paiar of levers with first ends pivotally connected to the frame above and in front of an exerciser supported on the seat. Each lever includes an intermediately located hub for holding a selectable weight resitance and a handle located at a second, lower end thereof adapted to be grasped and pulled rearwardly through a low row exercise motion by an exerciser supported on the seat. The levers pivot through planes which converge with respect to the forward facing direction of the exerciser. The orientation of the frame, the seat and the levers, and particularly the convergence of the levers and the angles of connection of the handles with respect to the levers readily accommodate the natural musculoskeletal makeup of the human body during the performance of a low row exercise motion, thus maximizing the muscular benefit attainable through performance of this exercise motion.
