Commercial Stair Climbing Performance in a Compact Footprint

Bring the signature StairMaster training experience to spaces where every metre matters with the StairMaster 4G Series StairMill. Designed as a compact stair-climbing solution, the 4G combines a space-conscious footprint with a broad resistance range, integrated controls and flexible console options.

With a footprint of approximately 54 x 29 inches, the 4G is designed for home gyms, boutique studios, hospitality facilities and multi-housing fitness environments where a larger StairMill may not be practical.

20 Levels of Training Intensity

Choose from 20 resistance levels and a step rate ranging from 24 to 162 steps per minute. The broad adjustment range makes it easy to create everything from controlled steady-paced sessions to demanding stair-climbing workouts.

Redesigned Multi Position Handrails

The integrated handrail system provides multiple climbing positions, allowing users to find a comfortable setup throughout different training intensities. Conveniently positioned speed controls and a stop button keep essential adjustments within easy reach.

Accessible Step Up Design

A 14-inch step-up height provides convenient access to the climbing area, while ergonomically proportioned steps create a stable platform throughout each workout.
