Abstract
Abstract An improved adjustable exercise machine for safe, smooth and comfortable aerobic conditioning has a frame assembly, a pair of foot skates with rollers attached to each skate permitting the skates to be movably mounted on the frame assembly and a pair of arm pole mechanisms attached to the frame assembly. The improvement comprises the frame assembly having two elongate parallel rails, suitably of extruded aluminum, each having sidewalls each with an elongate groove therein with recesses within the grooves thereby forming sidewall tracks. The rails each have a bottom with an elongate groove therein having elongate recesses within the groove thereby forming a bottom track. The rollers of each skate are adapted to be securely and movably mounted within the respective sidewall tracks of the rails to secure or fasten the skates to the rails. The skates have an inclined top surface sloping downwardly in a forwardly direction. The arm pole mechanisms are adapted to be adjustably attached to the bottom track of the respective rails to permit transverse adjustment of the arms poles with respect to the rails.
