Abstract
A cross country ski exerciser has an adjustable forward support that provides for changing the inclination of the frame. The adjustable support permits automatic adjustment of the frame inclination in a series of steps. The adjustment mechanism will reset so that it can be collapsed to a frame lowered position, returned to an operative position and automatically be operative to support the frame. The ski exerciser has folding frame components for compact storage utilizing a single bolt latching arrangement. An arm exerciser supported on the frame has a flywheel for insuring smooth arm movement during the exercise sequence.
