Abstract: Exercise apparatus, which may be an elliptical cross trainer, has a rotating inertial flywheel driven by user-engaged linkage exercising a user. A user-actuated brake engages and stops rotation of the flywheel upon actuation by the user.

Abstract: To provide variable resilient support for the deck of an exercise treadmill one or more resilient members are secured to the deck and a moveable support member is used to selectively engage the resilient members to provide support for the deck. A user operated adjustment mechanism can be used to move the support member or support members longitudinally along the treadmill thus effectively changing the number of resilient support members supporting the deck.

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.
