KEY TAKEAWAYS
- A smart treadmill adjusts your workout automatically in real time based on heart rate, training history and fitness level — a traditional treadmill requires you to set everything manually.
- NordicTrack's Follow Trainer, SmartAdjust™ and ActivePulse™ are the three core adaptive features; all require an iFIT Pro Membership ($39/month).
- Smart treadmills are worth the premium when you need engaging content to keep you coming back and guided workouts that adapt in the moment to keep you progressing over time; traditional treadmills make more sense for self-directed athletes who already know what they need.
- The X24 offers −6% to 40% incline range — the widest in the NordicTrack lineup — for walkers and hikers who want to burn more calories without increasing speed. The Commercial 2450 covers beginner-to-advanced progression with speeds up to 14 MPH and incline-to-decline training. The T Series 10 is the entry-level smart option.
- An iFIT membership includes an extensive library of progressive guided workouts that adapt to your fitness level over time. Manual mode is always available without a subscription.
FOUR CRITERIA FOR EVALUATING WHETHER A SMART TREADMILL IS WORTH IT
NordicTrack has established these criteria for evaluating whether a smart treadmill is worth the investment. If a treadmill passes most of these tests, it's likely worth it. Add the subscription cost to the purchase price — then compare that number to whatever you're currently spending on gym memberships you're not using.
Does It Remove Decision Fatigue From Your Workouts?
The best workout is the one you’ll actually do. If you have to plan every session yourself, that planning becomes the first thing you skip. A wide variety of immersive, guided workouts keeps you motivated and training fresh—so consistency feels easier and fitness becomes a habit.
Does It Adapt to Your Fitness Level Over Time?
A treadmill worth buying gets harder as you get fitter without you having to manually reprogram it every few weeks. Automatic adjustments that match your fitness level let you just press start and go.
Does It Support Long-Term Progression?
Look for structured programming that builds on previous sessions rather than offering the same fixed options forever. Progression is what keeps you improving past the first few months.
Does It Reduce the Friction That Causes Most People to Quit?
The biggest threat to your fitness routine isn't effort, it's starting. Zero-session planning, built-in coaching, and automatic adjustments have a structural advantage over any machine that depends entirely on your self-direction.
SMART TREADMILL VS. TRADITIONAL TREADMILL
The specs below can affect whether the machine gets used, not just how it looks on paper.
Smart Treadmill (iFIT Enabled)

Auto workouts
Speed, incline, and decline adjust automatically to follow your trainer — so you focus on training, not the controls.
Auto speed & incline
If you modify a setting mid-session, SmartAdjust™ recalibrates the rest of the workout to keep overall effort right — and adjusts future workouts so you're always progressing.
Auto heart rate training
ActivePulse™ reads your heart rate and automatically adjusts intensity to keep you in the right training zone throughout every session — no manual checks required.⁴
Coaching
Progressive multi-week plans build and evolve as you improve — AI Coach schedules every session, adjusts recommendations as you progress, and ensures you never have to plan what comes next.
Workout library
10,000+ guided workouts filmed worldwide — new destinations and trainers added continuously so training stays fresh and consistent long term.
Subscription required
iFIT Pro membership powers all smart features. Plans start at $39/mo. 1-year, 2-year, 3-year plans available for as low as $25/mo⁸
Smart treadmill is best for
Consistency and variety seekers would benefit most from a smart treadmill
Traditional Treadmill

Manual workouts
You plan, set, and manage every session yourself — no guidance, no automatic adjustments, no progression built in.
Manual speed & incline controls
You control every speed and incline change manually throughout the session — which makes it easy to default to whatever feels comfortable rather than what's actually challenging you.
User monitored heart rate
You monitor your own heart rate and adjust intensity yourself — without automatic corrections if you drift out of your target training zone.
No built in coaching
No structured plans, no session scheduling, no progression tracking — you decide what to do every time you get on the machine.
No workout library
No guided content, no variety, no new destinations or trainers — the same experience every session.
Subscription not required
No membership needed. You control speed and incline manually and train on your own program.
Traditional treadmill is best for
Experienced or self-directed athletes would benefit most from a traditional treadmill

WHAT MOST BUYERS GET WRONG ABOUT THIS DECISION
Most people compare smart and traditional treadmills on specs: motor size, belt dimensions, top speed, max incline. Those things matter — but specs alone may not determine whether a treadmill collects dust after month two. The real question is simpler: Will this machine make it easy for me to build a habit I can sustain?
Specs Don't Create Accountability
A 3.5 CHP motor won't remind you to work out, adjust for a bad week, or tell you when to push harder.
Manual Controls Add Decision Fatigue
Every session, you decide the speed, incline, duration, and plan. That's decision fatigue stacked on top of already needing motivation.
Consistency Beats Intensity
The one with sustained motivation to show up five days a week on a smart treadmill has a good chance of outperforming the one who starts out strong on a new machine but drops off as interest fades.
The Subscription Has to Earn Its Keep
Smart features require an iFIT membership. If they genuinely make you more consistent, the subscription earns its cost. If you'll skip them, you're paying smart-treadmill prices for a basic experience.
HOW SMART TREADMILL FEATURES TRANSLATE TO REAL-LIFE OUTCOMES
Features only matter when they change what happens during and after a workout. Here's what NordicTrack's smart technologies actually do when paired with an iFIT membership.

Intensity That Adapts as You Train

Stay in the Right Zone

Your Trainer Controls the Machine

No Guesswork, Just Press Start
CHOOSE THE RIGHT TREADMILL FOR YOUR GOALS
NordicTrack treadmills are built to support specific fitness goals from weight loss and strength building to healthy aging. Here’s how to choose the right features for you.

Best treadmill for weight loss
- Incline variability: Burn more calories without needing to sprint with incline training. The X24 has a steep 40% incline.
- Immersive, guided workouts⁶: Stay motivated and keep progressing.
- Auto speed & incline⁶: Real-time adjustments that match your fitness level.
- Cushioned deck: Designed to reduce impact so you can train longer and more often.

Best treadmill for increasing endurance
- Progressive workouts⁶: Week-by-week plans for steady progress.
- Higher top speeds: Enable intervals, sprints, and pace progression without your treadmill holding you back.
- Incline variability: Engage a variety of muscles to build lower-body strength with -3% to 12%
- Auto speed & incline⁶: Real-time adjustments that match your fitness level.

Best treadmill for healthy aging
- Immersive, guided workouts⁶: Keep you motivated and progressing.
- Incline variability: Engage a variety of muscles to build lower-body strength with -6% to 40%.
- Auto speed & incline⁶: Real-time adjustments that match your fitness level.
- Cushioned deck: Designed to reduce impact so you can train longer and more often.
- You want variety without planning it: Trainer-led classes and global routes mean the workout changes every time. You just have to show up⁶.
- Consistency has been your biggest challenge: If past gym memberships went unused or your last treadmill became a clothes rack, that's exactly what smart features are built to fix. Guided workouts and reminders solve the starting problem — not the effort problem⁶.
- You want workouts that adapt to you: If you want a workout that meets you where you are — adjusting intensity, speed, and incline based on your fitness level and heart rate — smart features do that automatically. You're not just following a plan. The plan follows you.
- Budget is the primary constraint: Traditional treadmills cost less upfront with no subscription required. If the monthly fee doesn't fit your budget, a traditional treadmill gets you moving without the added cost.
- You're an experienced self-programmer: If you prefer to train on your own terms, know what you need, and don't need guided coaching, a traditional treadmill gives you full control without paying for features you won't use.
