StairMaster 4G Series Stairmill

Compact Power, Big Performance
The StairMaster 4G StairMill answers the demand for a powerful cardio solution that fits into smaller training environments without compromising performance. Designed to deliver the same intense, calorie-burning, low-impact stair-climbing workout the StairMaster name is known for, the 4G is ideal for home, hospitality, boutique studios, and multi-housing fitness spaces. With a compact footprint of just 54” x 29” and a ceiling clearance requirement of only 8 feet, it brings commercial-grade training into places the 10G and 8Gx simply can’t go.

Smart Design, Enhanced User Experience
The 4G’s newly redesigned handrail system provides multiple climbing positions and integrates speed controls, a stop button, and contact heart rate sensors for a safer, more intuitive workout. A 14” step-up height and ergonomically sized steps make it accessible to a wide range of users. Its 20 resistance levels and step rate ranging from 24 to 162 steps per minute make it equally suitable for beginners and hardcore stair climbers alike.

Console Flexibility and Digital Integration
Choose from a range of OpenHub™ consoles, including a 10” LCD, 10” Touchscreen, or 15” Embedded Display. The 4G offers Bluetooth connectivity, telemetry heart rate tracking, USB charging, and HDMI streaming with the 15” model. Personal cooling fans and a built-in bottle and accessory holder add comfort and convenience to every session, while the console options support popular entertainment and fitness apps to keep users engaged.

Built for Maintenance and Longevity
Constructed with a durable powder-coated steel frame, the 4G is engineered for longevity in demanding environments. Maintenance is made easy with a quick-access service panel that removes with just four fasteners, streamlining servicing and reducing downtime. With user weight support up to 350 lbs and a reliable, responsive drive system, the StairMaster 4G is the perfect mix of performance, accessibility, and smart design.
