The StairMaster 4000 PT exercise system is a vertical climbing machine with an independent step action. The independent step action, combined with the patented pedal geometry featu red on all StairMaster steppers, provides an aerobic workout equivalent to uphill running or climbing stairs, but without the high-impact pounding to the joints and muscles.
