Lifespan Fitness Viper M4 Treadmill

The Viper M4 is built for serious runners who want performance without distractions. Powered by a 3.75 CHP EverDrive H7X brushless motor, it delivers smooth, consistent speed up to 20 km/h with the reliability needed for demanding daily training.

Its 1500mm x 520mm commercial-grade running surface gives you space to stretch out naturally, while Shock Control advanced cushioning reduces impact so you can train longer and recover faster. With 18 levels of automatic incline, you can instantly shift from flat sprints to steep climbs.

A clear LCD console keeps your key metrics front and centre—speed, distance, incline, pulse, and calories—while quick-select buttons let you adjust intensity without breaking stride. FitLink compatibility and built-in programs add structure when you want it, or freedom when you don’t.

Solid, spacious, and performance-focused, the Viper M4 is designed to handle consistent high-intensity training and keep pace with your goals over time.
