The Spirit Fitness CSC900 StairClimber is a great way to get a challenging yet rewarding workout. A sturdy industrial drive system ensures years of reliable, trouble-free service. The drive method, from steps to brake, is a chain connected to steps driving an electromagnetic induction brake by poly-v belt transmission. The 21.5" step width and 11" step depth provide one of any machine's most significant step surface areas, which increases safety while also easily accommodating training positions such as side crossover steps. The CSC900 has 11 pre-programmed workouts, 20 levels of resistance, and speeds up to 160 steps per minute to help you keep your fitness routines challenging. The multi-position handlebars include built-in hand pulse grips and resistance controls to assist you in staying in the zone.
