Decked out with an HD touchscreen that streams both live and on-demand workouts, NordicTrack's treadmill is a great investment for anyone who wants interactive, trainer-led workouts. This treadmill is so smart that the machine will auto-adjust speed an incline based upon your personal fitness goals. Then, track and celebrate all your progress in the app that monitors all your workouts.

Yes, this one's not exactly cheap, but it has over 20,000 five-star reviews and is one of Amazon's bestselling cardio machines.

Rave Review: "Took about one and a half hours to assemble with two people. It works great on the manual setting, but I LOVE using the iFit app on my smart phone. It is worth it to me. It synced seamlessly and it auto-adjusts the speed and incline with the trainer (you can also manually adjust and then switch back to trainer-led workouts at any time). All the trainers I've used so far have been really engaging, explaining the purpose of each part of the run, keeping motivation high, describing the landscape/history of the area we are running/walking through, and there is even music in the background. I absolutely look forward to my runs!!!! The quality is FANTASTIC!! I was worried because when I first turned it on, speed 1 was not totally smooth, but go up even to 1.5 or 2 and it's very smooth. 10/10 recommend. For the price, you can't beat it!"
