Horizon 7.8 AT is our Best Overall pick for the best treadmill with automatic incline. It combines motorized elevation with a full-size running deck, quick controls and hardware suited to interval training.
Automatic incline matters when you want to change training load without stepping off the treadmill. But “automatic” can mean two different things: a motorized incline that you control from the console, or software-driven grade changes that respond to a program or class. This guide distinguishes those features instead of treating them as interchangeable.

Key Takeaways
- Best Overall: Sole F89 — 82.3/100. Its 15% maximum incline is the highest in this shortlist, paired with a 22 × 60 in belt and 375-lb capacity, so it gives up the least elsewhere to deliver strong hill capability.
- Best Smart Incline: NordicTrack Commercial 2450 — 78.6/100. Choose it when automated connected training matters most; it combines 12% incline with the fastest top speed here at 14 mph, a 22 × 60 in belt and 400-lb capacity.
- Best Value: XTERRA Sport Series – TR75 — 81.9/100. The closest score to the Sole F89, with 12% incline, 12 mph speed, a 20 × 60 in belt and 350-lb capacity at a more value-oriented position.
- Best Alternative: Schwinn Fitness 815 — 79.6/100. A lighter 155-lb machine than the three premium alternatives, while still providing 12% incline, 12 mph speed and a 20 × 60 in belt.
- Best Large-Screen Option: Proform Pro 9000 (New) — 79.4/100. The choice to prioritize the console experience while retaining 12% incline, 12 mph speed, a 20 × 60 in belt and 350-lb capacity.
- Automatic incline is only the first filter. After confirming powered elevation, compare maximum grade, transition behavior, belt size and stability; those determine whether the incline is actually useful for your workouts.
- Account for ceiling height and machine mass. Incline raises the user above the flat deck, while heavier machines are harder to reposition even when they are more planted during training.
Best Overall: Sole F89
Sole F89 scores 82.3/100 and is our Best Overall.
- Max incline: 15%
- Speed: 12 mph
FitScore for Automatic-Incline Treadmills
Why Choose This Treadmill
Sole F89 earns Best Overall because it couples the strongest incline specification in this shortlist with full-size training hardware.
Its 15% maximum incline gives hill walkers and runners more elevation range than the 12% alternatives, while the 22 × 60 in belt and 375-lb capacity keep it suitable for broader everyday use. The trade-off is physical: at 314 lb, it is a machine you buy to leave in place rather than move around regularly.
Choose it when incline performance and a spacious deck matter more than portability.

Best Smart Incline: NordicTrack Commercial 2450
NordicTrack Commercial 2450 scores 78.6/100 and is our Best Smart Incline.
- Max incline: 12%
- Speed: 14 mph
FitScore for Automatic-Incline Treadmills
Why Choose This Treadmill
NordicTrack Commercial 2450 earns Best Smart Incline because it adds a stronger connected-training proposition to otherwise serious running specifications.
The 12% maximum incline is lower than the Sole F89’s 15%, but the NordicTrack counters with a 14 mph top speed, a 22 × 60 in belt and 400-lb capacity. Its 268.2-lb weight makes frequent repositioning unrealistic, and some smart workout functionality may depend on the current software or subscription.
Choose it when guided incline training matters more than having the highest raw incline percentage.

Best Value: XTERRA Sport Series – TR75
XTERRA Sport Series – TR75 scores 81.9/100 and is our Best Value.
- Max incline: 12%
- Speed: 12 mph
FitScore for Automatic-Incline Treadmills
Why Choose This Treadmill
XTERRA Sport Series – TR75 earns Best Value because it stays close to the winner’s overall score while trimming some of the premium hardware.
You still get 12% maximum incline, 12 mph speed, a 20 × 60 in belt and 350-lb capacity, which covers most home walking, jogging and running needs. At 216 lb it is still not a light machine, but it is easier to accommodate than the Sole F89 or NordicTrack.
Choose it when you want strong incline capability without paying mainly for the most premium deck or connected experience.

Best Alternative: Schwinn Fitness 815
Schwinn Fitness 815 scores 79.6/100 and is our Best Alternative.
- Max incline: 12%
- Speed: 12 mph
FitScore for Automatic-Incline Treadmills
Why Choose This Treadmill
Schwinn Fitness 815 is the Best Alternative for buyers who want the core incline and running specifications in a noticeably lighter package.
Its 12% maximum incline, 12 mph speed and 20 × 60 in belt match the basic training envelope of the XTERRA and ProForm, while the 155.08-lb machine weight makes placement and relocation less daunting. You give up some of the premium feel and broader feature set of the top picks.
Choose it when practical ownership matters almost as much as incline performance.

Best Large-Screen Option: Proform Pro 9000 (New)
Proform Pro 9000 (New) scores 79.4/100 and is our Best Large-Screen Option.
- Max incline: 12%
- Speed: 12 mph
FitScore for Automatic-Incline Treadmills
Why Choose This Treadmill
ProForm Pro 9000 earns Best Large-Screen Option because its main advantage is the interface and guided-training experience rather than a higher incline ceiling.
The underlying treadmill still provides 12% maximum incline, 12 mph speed, a 20 × 60 in belt and 350-lb capacity, so the screen does not come at the expense of basic training capability. At 218.1 lb it is a substantial machine, and the value of the display depends on how much you will use connected content.
Choose it when the screen is part of the workout, not just a specification on the box.

How We Selected the Best Treadmill With Automatic Incline
We started with the search intent itself: motorized incline that changes without manual intervention. Products that do not satisfy that primary requirement are filtered or penalized before secondary features are considered.
Within the eligible set, we give extra weight to incline range, transition usability, controls, deck size, speed, capacity and stability. The six FitScore dimensions—Performance, Durability, Comfort, Practicality, Features, and Affordability—are interpreted through this use case rather than treated as identical across every Best guide.
We also model the trade-offs explicitly. Manual incline does not satisfy the core requirement. A treadmill can therefore rank below a generally stronger model when its advantages do not match the buyer intent on this page.
Finally, we verify specifications against the exact product revision or ASIN wherever possible, including capacity, belt dimensions, speed, incline, machine weight, folding dimensions, connectivity and current price data. Similar model names are not treated as interchangeable, and ambiguous specifications are left unverified rather than inferred. These rankings are research- and specification-based; they do not imply hands-on testing unless we explicitly say so.
How to Choose the Best Treadmill With Automatic Incline
Decide whether you need motorized incline or program-controlled incline. Every pick here can change elevation automatically through a motor, but software-driven changes may depend on a specific app or subscription.
For interval training, prioritize quick-access controls and responsive transitions. Repeatedly opening a touchscreen menu to change grade is less practical than dedicated buttons or dials.
Check ceiling clearance at maximum incline. The front of the deck rises, increasing the user’s effective standing height.
For incline walking, handrail position and deck stability matter because steeper grades change body angle and foot placement.
If you run, do not let a large incline range distract from belt length, width, top speed and cushioning. Those determine whether the treadmill works for your normal training when the deck is flat.
Decision Shortcuts
- Best Overall: Sole F89 — Pick it for the highest maximum incline here (15%) plus a 22 × 60 in deck and 375-lb capacity.
- Best Smart Incline: NordicTrack Commercial 2450 — Best when connected incline workouts matter most; 12% max incline, 14 mph top speed, 22 × 60 in belt and 400-lb capacity.
- Best Value: XTERRA Sport Series – TR75 — Closest FitScore to the winner while retaining 12% incline, a 20 × 60 in deck and 350-lb capacity.
- Best Alternative: Schwinn Fitness 815 — Sensible if you want 12% incline in a substantially lighter 155-lb machine.
- Best Large-Screen Option: Proform Pro 9000 (New) — Choose it primarily for the screen experience while keeping 12% incline and a 20 × 60 in running surface.
Final Verdict
Sole F89 is our #1 pick at 82.3/100 because it combines the highest maximum incline in this group at 15% with a full 22 × 60 in deck and 375-lb capacity. It is the strongest default when you want incline capability without making the incline feature the only thing the treadmill does well.
NordicTrack Commercial 2450 is the smarter connected alternative if guided incline changes and a 14 mph top speed matter more, while the XTERRA TR75 is the value play with a very close 81.9/100 FitScore. Schwinn 815 makes more sense when moving a lighter machine matters, and the ProForm Pro 9000 is the screen-first choice.
Before buying, verify maximum incline on the exact revision, available ceiling clearance at full elevation, and whether any automatic workout adjustments require a subscription. Those details matter more than a generic “automatic incline” label.
Frequently Asked Questions About the Best Treadmill With Automatic Incline
It means the treadmill uses a motor to raise or lower the deck rather than requiring manual repositioning. Some models can also change grade automatically through workout software.
No. Automatic/motorized incline means powered elevation. AutoAdjust-style features use software to change incline for you during a program or class and may require a subscription.
For most home cardio, moderate incline already increases effort substantially. Higher maximum incline is useful for steep hill walking, but transition quality and deck stability also matter.
That depends on the model, user and training goal. Very steep settings are usually more appropriate for walking or hiking-style workouts than high-speed running.
The incline motor creates temporary mechanical noise while the deck moves. It is usually intermittent rather than continuous, but implementation varies by model.
Yes. The raised front deck lifts the user higher, so low-ceiling rooms should account for deck height plus maximum incline and user height.
