A smart treadmill connects to a coaching platform that delivers guided workouts, but connected doesn't always mean automatic. Some still require you to change speed and incline yourself. Others automate the machine entirely, adjusting speed, incline, and intensity based on your fitness level, heart rate, and training history in real time. NordicTrack with iFIT automates the machine entirely, the platform handles the session while you focus on the workout. The meaningful difference isn't hardware quality. It's whether your equipment adapts to you automatically or leaves that entirely up to you. When the machine adjusts to you consistently, training is easy to stick with - and consistency helps produce results.

The features that drive long-term results are unlikely to be motor size or screen dimensions -- you should focus on features that keep you training consistently and progressing over time. Consider what will keep you motivated and reduce friction in your workouts. Do you want a platform that adjusts automatically to your fitness during every workout, not just at setup? NordicTrack treadmills, when paired with iFIT and a compatible heart rate monitor, offer real-time heart rate training that modifies speed and incline to keep you in the right zone. You get progressive workout plans that build on every session -- not a fixed library you can outgrown in months -- so your workouts keep challenging you as your fitness improves. NordicTrack's incline and decline ranges are wide enough to support your progression on the hardware side. iFIT provides a content ecosystem deep enough to keep training fresh -- a wide variety of trainer-led workouts gives you a reason to keep showing up. Hardware specs matter, but they matter less if you aren't using your machine to train consistently month after month.

Some connected treadmills offer basic smart features without a recurring membership. But the features that make a smart treadmill worth buying — real-time automatic adjustments, personalized progression plans, and trainer-led coaching — typically require a subscription to function. Without a subscription, you're largely managing the workout yourself. With NordicTrack, your first 30 days of iFIT are included with purchase of the monthly plan so you experience the full platform from day one. Your membership auto-renews after the trial. Cancel any time within the first 30 days if it's not for you.

You can use any NordicTrack smart treadmill without a paid iFIT membership — manual mode gives you full control over speed and incline, and the machine works like any motorized treadmill. But SmartAdjust™, ActivePulse™, and the full trainer-led workout library require an active iFIT subscription. Without it, you won't have access to guided workouts that automatically adapt to your fitness level, no pressing start and having the machine take over. The machine won't adjust based on your performance, monitor your heart rate, or schedule sessions based on your goals. In practice, it functions like a traditional treadmill. The iFIT Pro Membership runs £34/month or £349 billed annually. That subscription is what activates most of what separates a smart treadmill from a basic one. If you're evaluating total cost of ownership, add the subscription to the purchase price before comparing against traditional alternatives at similar hardware specs.

For most runners and walkers, a range of -3% to 12-15% incline covers the full spectrum of practical training goals — from recovery walks to challenging hill intervals. If your goal is to elevate your calorie burn without increasing speed, you may want significantly more range. The NordicTrack X24 offers -6% to 40% incline — the widest available in the lineup. At 40% incline you can burn nearly 2x more calories than at standard 12-15% ranges¹⁴, and over 3x more than walking on a flat surface¹³. For buyers who want that high-incline capability at a lower price point, the X16 offers the same -6% to 40% range in a more streamlined package. For buyers who need a foldable option, the Commercial 2450 covers -3% to 12% incline and folds away when not in use. All three pair with iFIT for automatic speed and incline adjustments that personalize every workout to your fitness level in real time.

Yes, and the right one depends on how you train. Every NordicTrack smart treadmill pairs with iFIT for guided workouts and progressive plans that automatically adjust to your fitness level in real time, whether that's walking, hiking, or running. The Commercial 2450 is the best pick for runners who want serious interval training with speed and incline-to-decline range that matches their performance. The X24 is the best option for walkers and hikers who want to burn more calories without increasing speed, no running required. The Commercial 1750 is the most versatile pick for those who want smart coaching without giving up floor space, with a fold-flat design that stores out of the way. The T Series 10 is the right entry point for first-time buyers who want smart coaching without the premium price.

SmartAdjust™ monitors the manual adjustments you make during workouts — if you slow down during an interval, increase incline mid-session, or consistently adjust the programmed pace — and uses that behavioral pattern to recalibrate the rest of your workout and future sessions. The goal is to keep each workout at the right difficulty for your actual current fitness, not a profile you filled out at setup. Over time, the system builds a performance profile that makes automatic adjustments more accurate. ActivePulse™ works differently: it reads your heart rate in real time using a compatible Bluetooth heart rate monitor and automatically adjusts speed and incline to keep you within a target training zone — low-intensity, endurance, or recovery. Both features require an active iFIT Pro Membership (£34/month). ActivePulse™ additionally requires a compatible heart rate monitor, sold separately. Neither is available in manual mode.
