It has a maximum weight capacity of 300 pounds, and OneTouch controls make it very user-friendly. Plus, users rave about the variety of workouts provided by the iFit platform, saying that the programming has invigorated their somewhat stale routine and made them look forward to their workouts.

It can reach an incline of 12%, and while slightly narrow for smaller spaces, it is plenty long for both runners and power walkers to use comfortably.

It can support a maximum capacity of 240 pounds, and it folds up and rolls away for easy storage when not in use. What’s more, its Bluetooth connectivity allows you to sync your smart devices for effective workout tracking and blast your favorite workout tunes straight from the treadmill’s built-in speakers.
