Product Summary

The Nautilus T616 treadmill is the company’s entry level machine. Despite its entry-level status, it comes with many features, including: 0-12 mile-per-hour speeds, 0-15% incline grades, 26 workout programs, SoftDrop folding system for storage, StrikeZone cushioning, and adjustable 3 speed fan for comfort.

The 26 workout programs include manual/quick start, interval training, heart health, and custom workouts. Runners can also sync with the Explore the World App to run through 27 routes in 19 locations around the world with a subscription and three free courses. The app does have poor reviews, with users struggling with buffering and slow video playback. If you’d like an immersive global run, a more technologically advanced treadmill would be a better option.

Customer reviews of the Nautilus T616 are mixed. Positive reviews state that the T616 is solidly built, easy to set up, and simple to use. Negative reviews complain that the T616 is noisy and slow to change speeds. They’ve also reported difficulty with the T616 synching with various apps and struggling to maintain a connection with the included heart rate monitor chest strap.
