The StairMaster 4400 PT FreeClimber offers many of the advantages of the original StairMaster 4000 PT, while encouraging your best workout posture. Without handrails or bars to lean on, the StairMaster 4400 PT makes sure all your exercise focus is placed on the lower body. To that end, the 4400 PT also offers independent pedal geometry and an enlarged sweet-spot to make your climbing smoother and more enjoyable. Once you’ve reached your peak, the StairMaster 4400 PT’s electronically controlled brake brings you down gently. The 4400 PT also employs a unique quiet-drive transmission that provides smooth and responsive operation.
