Abstract
A cross country skiing exercise machine has an upright member and an extension member which are structured to move between a first upright configuration and a second configuration in which they are collapsed. The main member is positioned substantially between the parallel tracks of the cross country ski exercise machine. The feet underneath the exercise machine constitute posts about which a reciprocating strap is trained. A rotatably pair of posts are positioned about the strap to tension the strap to cause increased friction and in turn increased resistance to movement of a first trolley and a second trolley which are positioned on the tracks for operation by the user in the performance of cross country type exercises.
