What We Love About the Nautilus T616 Treadmill:

The Nautilus T616 Treadmill pulls out all of the conveniences that people wish for in a piece of exercise equipment. It has an MP3 player, tons of programmed workout programs and three different options for performance tracking. It’s connectivity to devices is nearly unmatched by competitors.

Programs & Tracking Capability

The DualTrack™ console on the Nautilus T616 Treadmill is very nice. This console has two backlit screens that display your workout data and is easily viewable in low light. It also has 26 programs that will hit everything from causal workouts to heart rate profiles to intense interval training. The best feature about the computer on T616 Treadmill, however, is that it has Bluetooth connectivity to transfer your workout data through Nautilus Connect, the Nautilus Trainer App or MyFitnessPal. Features like these are great because they make using the T616 Elliptical enjoyable and keep you coming back for more exercises.

What Isn’t So Great:

There are some reports concerning various issues with the displays.  Some of the issues include very fluctuant heart rate readings, problems with user profile settings, and inaccurate time, distance and calorie readings. Make sure that you protect yourself by purchasing this product from a reputable dealer like If you are one of the unlucky, the warranty should solve the problem.

Final Word on the Nautilus T616 Treadmill:

For its price range, the Nautilus T616 Treadmill is an excellent buy.  It’s a bit higher in price than the Nautilus T614 but you’re getting a lot more machine. This treadmill has all of the bells and whistles. It has tons of exercise programs and awesome connectivity to track your workout performance. On top of that, Nautilus is a great manufacturer of exercise equipment and known as a very reputable company. So, if you do end up with a faulty piece of equipment, chances are with Nautilus, the issue will be resolved quickly.

    Does anyone know what temperature ranges this machine can be stored in? We are looking at this machine but will store it in off seasons on our screened in porch. We live in Atlanta where it can get very cold and very hot.

      Hi Anne, thanks for writing. According to Nautilus representatives I spoke with, they recommend keeping your treadmill in a climate controlled environment indoors. The electronics can be damaged by excessive cold and heat. Excess moisture should also be avoided. Hope that helps!
