Still the toughest workout in the gym, the StairMaster StepMill revolving staircase most closely duplicates the workout of real stair-climbing. Its new quieter step design improves fluidity of stepping motion and provides added cushion for joints. It includes a new easy-to-read, back-lit LCD console and new handrails which are ergonomically designed for a maximum level of intensity. Programs include a nationally recognized fitness test to gauge individual progress and a custom firefighter test (C.P.A.T. – Candidate Physical Ability Test). Also includes a Polar® compatible telemetry Heart Rate monitoring system.
