The Stairmaster 7000PT Stepmill is a heart accelerator at its finest. The revolving staircase varies in speeds from 24-162 steps per minutes with 8” step height which resembles the step height of that staircase you avoid at work. Electronically-controlled alternator with chain drive precisely controls the pedal descent allowing a wide range of users to exercise smoothly within their comfort zones. It also provides an easy to read monitor, 9 motivating programs and includes a bottle holder to keep you hydrated while you are hard at work. This is a great addition to any facility. We recommend that you have a 10ft ceiling as these machines are fairly tall.
