STAIRMASTER SM5 Stepmill

For 25 years, the StairMaster StepMill has been called the toughest workout in the gym. Now you can bring that same toughness to your home workouts with the totally redesigned SM5. The StepMill is easy to recognize - it's the piece of cardio equipment that looks brutal compared to all the others, with a revolving set of 8-inch stairs that closely duplicates the workout of actual stair climbing.
