Sole F89
Sole F89 ranks #1 in this guide with a FitScore of 86.6/100. It earns the top spot with a 4 HP motor, 22 × 60-inch deck, 15% incline, 6% decline and a 375-lb rating for steady, varied cardio.

Why Choose This Treadmill
Read our full Sole F89 review for specs, owner feedback and alternatives.
If you want one treadmill for every kind of cardio session, the Sole F89 is the most complete choice here. Its 4 HP motor, 12 mph top speed and 15% incline cover brisk walks, steady runs and climbs.
A 22 × 60-inch deck with Cushion Flex Whisper Deck cushioning gives room for a full stride, and 6% decline adds variety. Reviewers found the deck very stable but firm on landing, which may not suit sensitive joints. The 375-lb rating, 21.5-inch touchscreen, 12 built-in programs and third-party app support round it out.
At about 314 lb it is heavy to move. In reviews, speed changes were slow, about 40 seconds from 1 to 12 mph, so it suits steady cardio better than sprint intervals. If you train often and want a treadmill that handles every pace and grade, it is the one to check first.

Why Choose This Treadmill
Read our full Horizon 7.4 AT review for specs, owner feedback and alternatives.
The Horizon 7.4 AT suits cardio users who want a wide, stable deck and steep incline. Its 22 × 60-inch deck matches the Sole F89 for room, and its 15% incline matches the Sole F89 as the steepest here. Reviewers found the motor strong and quick to respond to speed and incline changes, which helps with intervals.
A 3.5 HP motor and 12 mph top speed handle walking and running, and 3-zone variable response cushioning adds comfort. In reviews, the deck felt comfortable without being soft. It folds, has 10 built-in programs and works with third-party apps.
At about 318 lb it is the heaviest pick, and its 8.25-inch LCD is simpler than a touchscreen. If stability and incline matter most, it is a strong alternative.
⚖Compared with Our #1 Pick
Horizon 7.4 AT is preferable to Sole F89 when you want the same deck size and incline with a longer 5-year parts warranty. If you want decline and a large touchscreen, the Sole F89 is the better fit.

Read our full NordicTrack Commercial 1750 review for specs, owner feedback and alternatives.
The NordicTrack Commercial 1750 is for cardio users who want the most motor and capacity in this guide. Its 4.25 HP motor and 400-lb rating are the highest here. In reviews of the current version, the motor handled every pace from slow recovery walking up to marathon-specific training.
A 22 × 60-inch deck with RunFlex cushioning, 12% incline and 3% decline cover walking, running and hill work. The 16-inch touchscreen and iFIT compatibility add guided sessions. Noise measured mid-pack in one test, around 45 dB at walking pace and about 66 dB at 7.5 mph.
Its 10-inch step-up is tall, and full guided content needs an iFIT membership. If you want guided cardio with plenty of headroom on capacity, it is a strong option.
⚖Compared with Our #1 Pick
NordicTrack Commercial 1750 is preferable to Sole F89 when you want a 400-lb rating, RunFlex cushioning and iFIT classes. If you want 15% incline and a longer warranty, the Sole F89 is the better fit.

Why Choose This Treadmill
Read our full ProForm Pro 9000 review for specs, owner feedback and alternatives.
The ProForm Pro 9000 suits cardio users who stay consistent with guided workouts on a large screen. Its 16-inch touchscreen runs iFIT classes, and a 3.6 HP motor, 12 mph top speed and 12% incline cover brisk walks, steady runs and hill work.
ProShox cushioning sits under a 20 × 60-inch deck, the 350-lb rating suits most users and the frame folds. On the previous generation, testers found the motor accelerated smoothly with little frame flex in fast intervals, though incline changes were slow.
Full guided content needs an iFIT membership, it has no built-in programs without it and its 2-year frame and motor coverage is shorter than the Sole, Horizon or XTERRA. It has no decline, and its 20-inch deck is narrower than the 22-inch picks. If you want coached cardio on a large touchscreen, it is a sensible choice.
⚖Compared with Our #1 Pick
ProForm Pro 9000 is preferable to Sole F89 when you want iFIT classes on a 16-inch touchscreen in a lighter, 218-lb folding frame. If you want a 4 HP motor, a 22-inch-wide deck, 15% incline, 6% decline and a lifetime frame and motor warranty, the Sole F89 is the better fit.

How We Selected the Best Treadmill for Cardio
We started with the question cardio users ask most: which treadmill keeps up best with regular, varied cardio at home? That put performance and durability first in our weighting, followed by comfort, features, practicality and affordability.
We compared motor power, top speed, incline and decline range, deck length and width, cushioning, user capacity, training content and warranty information.
We favored stronger motors, 60-inch decks, useful incline ranges and long frame and motor coverage, because those matter most when a treadmill is used several times a week. Large screens and app features count for less here than how well the treadmill handles sustained walking, running and climbing. The final five cover different priorities: an all-round performer, a stable incline option, a high-capacity cushioned pick, a value choice and a large-screen iFIT pick.
Prices change often, so check the current price before you order.
How to Choose the Best Treadmill for Cardio
Start with the motor: The NordicTrack Commercial 1750 lists 4.25 HP, the Sole F89 4 HP, the ProForm 3.6 HP, the Horizon 3.5 HP and the XTERRA 3 HP. More motor power gives headroom for frequent sessions and running, and usually means the motor works less hard at everyday speeds.
Check the deck: The Sole F89, Horizon and NordicTrack have 22 × 60-inch decks, while the XTERRA and ProForm are 20 × 60 inches. A 22-inch deck gives more side-to-side room at running speeds, while a 20-inch deck still suits most walkers and joggers.
Consider incline and decline: The Sole F89 and Horizon reach 15%, the others 12%, and the Sole F89 and NordicTrack also offer decline. Incline lets you raise your effort without more speed, and decline adds variety for runners who want to mix up their sessions.
Compare capacity: The NordicTrack is rated for 400 lb, the Sole F89 375 lb, and the Horizon, XTERRA and ProForm 350 lb. Plan for the heaviest regular user with some margin, especially if several people will share the treadmill.
Decide on training content: The NordicTrack and ProForm use iFIT, the XTERRA has 18 built-in programs and the Sole F89 and Horizon work with third-party apps. Guided iFIT classes need a membership, while built-in programs give structure without an extra subscription.
For weekly activity targets, see the CDC's adult physical activity guidelines and the American Heart Association's physical activity recommendations. For cardio planning, a 2021 systematic review and meta-analysis comparing interval training with steady moderate training found broadly similar body-composition changes, so mix both on the treadmill and keep the routine you enjoy.
Decision Shortcuts
Best Overall: Choose Sole F89 if you want the most complete cardio treadmill here; choose Horizon 7.4 AT for a longer parts warranty.
Best Stability: Choose Horizon 7.4 AT if you want a wide deck and 15% incline; choose Sole F89 for decline and a touchscreen.
Best Cushioned Alternative: Choose NordicTrack Commercial 1750 if you want 400-lb capacity and iFIT classes; choose Sole F89 for steeper incline.
Best Value: Choose XTERRA Sport Series TR75 if you want full-size cardio; choose Sole F89 for more motor and deck.
Best Large-Screen Alternative: Choose ProForm Pro 9000 if you want guided iFIT cardio on a 16-inch touchscreen; choose Sole F89 for a wider deck and decline.
Final Verdict
Sole F89 is our first choice for most people shopping for a treadmill for cardio. Its 4 HP motor, 22 × 60-inch deck, 15% incline, 6% decline, 375-lb rating and lifetime frame and motor warranty give it the best balance of performance and durability here. Horizon 7.4 AT is the stable incline option, NordicTrack Commercial 1750 is the high-capacity cushioned pick, XTERRA TR75 is the value choice and ProForm Pro 9000 is the large-screen alternative.
For most people who want regular, varied cardio at home, Sole F89 is the model we would check first, after confirming its current price.

FitScore compares how well each treadmill fits home cardio across performance, durability, comfort, features, practicality and affordability using this article's weighting.
For regular walking and running, the models here list 3 to 4.25 HP. A stronger motor gives more headroom if you run often or share the treadmill.
A 22-inch deck gives more side-to-side room, which some runners find more comfortable at higher speeds. A 20-inch deck still suits most users.
