The NordicTrack C 850s is a sturdy choice for people who want to work out in the comfort of their homes. The 20" x 60" tread belt is capable of supporting weights of up to 325 pounds. Combined with 24 preset programs, you can work out to your heart's content with this long-lasting machine.

Is the NordicTrack C 850s Treadmill best for you?

The NordicTrack C 850s Treadmill is a great option for people who don't mind spending a little more for quality. You're comfortable through every step of your workout thanks to FlexSelect cushioning, which goes easier on your joints compared to pavement. Plus, you can push yourself to the limits with speeds of up to 12 miles per hour and inclines of up to 12 degrees.

As if that wasn't enough, you can also take advantage of iFit workouts with an optional subscription. You can exercise with motivation from world-class personal trainers guiding you through every facet of your regimen. With the built-in audio system, you can listen to anything you want right there within the machine.

Consider NordicTrack C 850s if...

  • You need a treadmill that offers a little something extra. Whereas other models, like the NordicTrack T 6.5s, only provide speeds of up to 10 miles per hour, this one goes up to 12 mph. Plus, it supports weights of up to 325 pounds in lieu of 300 that comes standard.
  • You want the SpaceSaver design. If you're short on space, then you don't always need to keep this treadmill out. With EasyLift Assist, you can effortlessly fold it up and put it out of the way until you want to use it again.
  • You like a built-in audio system. Using headphones to listen to your workout playlists can become cumbersome quickly. With this machine, you can plug your device in and blast music over the speakers.

Avoid NordicTrack C 850s if...

  • You need to browse the internet. Some of the more contemporary treadmill models provide you with a touchscreen, allowing you to access the web. You don't get that here.
  • You want to monitor your heart rate wirelessly. You can keep track of your heart rate with the grip sensors in the handlebars. However, this machine doesn't include a wireless chest strap.
  • You don't like noisier treadmills. The 2.75CHP motor in this treadmill is decently powerful. But some users note how it can get pretty noisy, especially when you run at higher speeds.
