An improved cross-country skiing simulating exercise machine for providing interactive aerobic conditioning has a base frame, a pair of foot skates movably mounted on the frame, and a pair of arm poles attached to the frame. The frame has two elongate parallel rails, suitably made of extruded aluminum, each having sidewalls with an elongate groove therein with recesses within the grooves thereby forming sidewall tracks. The skates are securely and movably mounted on the rails and have an inclined top surface sloping downwardly in a forwardly direction and a toe kick at their forward end. The arm poles are at the sides of the front end of the frame, and an electronic sensing, control and display assembly is mounted on the frame between the arm poles. An interactive video skate resistance mechanism for automatically adjusting the difficulty of moving the skates is provided.
