Zero Runner ZR8 Features

A key feature of the Octane ZR8 is its adjustable stride, which naturally adapts to your gait. Simulate stair climbing, run or walk while putting zero impact on your frame! This machine also has free-moving performance handlebars that can support the natural arm motion you’d use when running outside. Using these can help you improve upper body strength, core strength and balance.

Compared with the ZR7 this unit helps you run especially fast. It has lightweight pedals made of aircraft grade aluminum to support smooth, quick and natural motion.

Resistance is adjustable and easy to vary during your run. Turn the resistance down for sprinting or turn it up to trigger your hamstrings, glutes and quads. Use interval training with resistance adjustments to become a stronger runner overall.

The ZR8 has Stride Tracing to help you monitor your form. This feature helps keep you aware of fatigue and encourages better posture for better performance.

For heart rate monitoring the ZR8 is compatible with Bluetooth, Polar and ANT+ transmitters. A chest strap is included.  Zero Runners also have contact sensors.

The console runs on batteries, so the machine doesn’t have a power cord.
