The Spirit Fitness XS895 Adjustable Incline Stepper takes your HIIT workouts to a new level.  It provides you with an arched incline adjustment that changes not only the stepping incline but also the height.
 
The additional 20 levels of resistance allow users of all fitness levels to maximize this effective lower body workout.  The narrow 2" pedal spacing (Q-Factory), large cusioned pedals, and multi-grip handlebar design combine to give you an incredibly comfortable and space-efficient cardio unit.
