StairMaster 4 Series 4G Compact StepMill w/ 15″ Embedded Display – New for 2026

Answering the call for a StepMill that can fit into more spaces and reach more users, we are excited to introduce the much anticipated StairMaster 4G. As the newest addition to the StairMaster family, the StairMaster 4G StepMill delivers the same heart-pounding cardio workout with a great calorie burn through a low-impact stair climb. Designed to fit perfectly into hospitality, boutique, and multihousing training centers, the 4G has harnessed the quality members have experienced over the past 4 years with the StairMaster 10G and the recently launched StairMaster 8Gx. With a footprint of 54” x 29” and a height clearance of only 8 feet, the 4G is the solution the fitness equipment market has been missing.
 

The 4G has a 15″ Embedded OpenHub console, a safety-stop sensor and a redesigned handrail system that supports multiple climbing positions and includes integrated speed and stop controls for a better user experience. Additionally, the service panel is secured with four fasteners and can be removed, allowing for easy access to the drivetrain and electronics.

Device Connectivity
Our OpenHub 15” Embedded Console connects directly with an Apple Watch and Samsung Galaxy Watch for real-time data sharing between gym equipment and watch. NFC technology allows for a simple tap to pair connection, making data tracking that much easier.
