If trusted quality, technological advancements, and a focus on interval training sound good, have we got a review for you!


Build Quality

If you’re a dedicated runner looking for a treadmill to keep up with your pace, the Horizon 7.8 AT Treadmill is a genius pick. Built using the strongest motor Horizon Fitness offers, this model was created to go the distance.

The Rapid-Sync Motor System comes revving powerfully with a continuous-duty 4.0 horsepower motor and an impressive 500 pound thrust incline motor to ensure longevity and durability for endless runs you can trust. Utilizing a Johnson Digital Drive System ensures the 7.8 AT treadmill wards off any lagging as you seamlessly adjust your speed or incline without second thought. These incline and speed shifts have proven to be 33% more rapid than competing treadmill motors, making the 7.8 truly the option to beat.

Fighting any feeling of confinement is the extra-large 22” x 60” deck that will give you the space you need to move freely. While designed for your home, the 7.8 AT treadmill meets the size and technology of commercial-grade standards, verifying further it’s ready for heavy personal usage.

Offering joint protection is the aptly created 3-Zone Variable Response Cushioning that Horizon uses on this treadmill to further remove any obstacle from you hitting your stride. Using only heavy duty materials to build their products, Horizon Fitness is a thoughtful brand whose intention is to offer a treadmill that will last a lifetime.

Not only is this model the top of the line of the advanced Studio Series, it’s also the ultimate peak of Horizon treadmills as its the best one they offer. The 7.8 AT treadmill is for fitness savants who are searching to raise their exercise capacity with the greatest model in function, performance and technology offered by the dependable Horizon Fitness brand.



If you’re hoping to be impressed by technology, you’ve arrived at the right choice of treadmill model to research as the Horizon 7.8 AT treadmill is the most technologically advanced option available through Horizon Fitness.

Setting it apart completely from not only any other Horizon treadmill, but also the competing Sole brand is the 9.3” High Contrast Color TFT Screen which the 7.8 AT boasts. This vibrantly colored screen brings both excitement and accessibility to interval training with its 60-second countdown timer, which allows you to achieve high intensity interval training from home (HIIT).

Furthermore, the 7.8 AT comes with an additional 16-digit alpha numeric LED screen for display variety. Helping you adjust your speeds and incline levels easily are the dynamic quick precision dials. By far our favorite feature as it’s not seen on other treadmills we’ve reviewed, these quick precision dials allow you to dial upwards to increase speed (the right dial) or incline (the left dial) and roll backwards to decrease, making your workout routine adjustments more seamless than ever.

The bluetooth technology provides built-in speaker pairing to get a theater-esque experience as you move. These integrated speakers pair quickly with your phone or tablet so you can stream online fitness classes, listen to music or catch up on the latest shows or movies you’re interested in, making your workout something you can look forward to.

The Rapid Charge USB port keeps your devices alive as you yourself spring to life through activity for as long as your heart and legs desire. Two tablet holders grant you options in regards to device placement. However, the greatest perk of these holders is that, unlike cheaper Horizon models, the 7.8 AT treadmill places one of the tablet holders above all of your displays so your workout stats and that beautiful colored screen won’t be hidden, giving you quite the view.

Ramping up its function is the Pro App, which enables your work-out summaries to automatically transfer to your favorite fitness app so you can track your health gains. Coming with the best workout programs Horizon offers, this treadmill grants you access to two custom programs, Heart rate, Distance, Calorie, Hill Climb, Fat Burn, 5k and manual. Additionally, the 7.8 AT comes with the specialized Sprint 8 program which was created for interval training and provides quick results when you’re in a time crunch.

Built with forward thinking minds, the Horizon 7.8 AT treadmill is ideal for athletes looking for technology just as good as performance.


Price Point

It’s common that the best results often come at a higher cost and the Horizon 7.8 AT is no exception when comparing it to other Horizon Fitness treadmills. However, considering it’s fierce 4.0 continuous horsepower motor, updated technology, unmatched warranties and built to last longevity, this model is a steal when you consider it’s worth.

Hundreds of dollars cheaper than the Sole F85, which boasts the same power, deck measurements, build similarities, speed and incline but without the large 9.5” LCD colored screen the 7.8 AT has, this treadmill is a standout option. Adding to this, another comparable model, the NordicTrack T 9.5 S, is much more expensive than the 7.8 but only has a 3.6 CHP motor, which means you’re paying more for less power and also a smaller roller size, all to get a bigger 14” video screen.

If you want to save on money while investing in greater power that is built to last a lifetime, you can simply use your tablet with the 7.8 AT to stream video. That being said, if the 7.8 AT treadmill is a bit out of reach, a solution would be to power down to the 3.5 CHP motor 7.4 AT (or even the 3.0 CHP 7.0 AT), which is one step down in terms of performance and price.

Saving you a couple hundred dollars, the 7.4 AT comes with the same 15% incline and 0.5 mph-12 mph speed range, workout programs, warranty, two tablet holders and extended deck size. Essentially, the 7.8 AT upgrade comes with a more powerful 4.0 CHP motor, quick dial precision controls for easy transition and a vibrantly large 9.3” high-contrast color TFT screen that the 7.4 AT lacks. Ultimately, it’s what fits within your budget when considering what you value most out of a treadmill.


Pros and Cons

When it comes to the Horizon 7.8 AT treadmill, we can confidently say it’s a well-rounded, trusted and quality treadmill that comes with technology and motor power to meet the needs of any fitness buff at a great value, honestly giving it little downside.

While extremely price savvy for what it offers, the 7.8 AT is still a considerable investment. As noted in the price section, if you can sacrifice on motor power and technology, the Horizon 7.4 AT is another option which will save you a couple hundred dollars.

A downside to consider is the lack of downside, as the 7.8 AT does not provide decline in order to best mimic a hilly outdoor workout. However, it’s important to note that a decline feature will cost you a pretty penny to obtain.

As a reminder, the 7.8 AT is the absolute top treadmill option Horizon has on the table. As we previously mentioned, this treadmill has Quick Precision Controls designed for interval training, or anyone looking to shift speed or incline without breaking their stride.

Further making it set apart is the 9.3” High-Contrast Color TFT screen that attractively displays your data. We love how the FeatherLight Folding Frame is built tough to last, yet won’t intrude on your space with its deck folding ability to be stored easily away.

With the highest weight capacity Horizon offers, up to 375 pounds, a speed range of 0.5 mph-12 mph and 15% incline ability verifies the 7.8 AT is a great match for a variety of users. The 4.0 Rapid Sync Motor with a Johnson Digital Drive System makes the 7.8 AT actively responsive, smooth and powerful.

Overall, the Horizon 7.8 AT Treadmill is truly a phenomenal choice for those looking to go the trusted distance from their personal living space.

Warranty and Guarantee

Something Horizon Fitness does extremely well besides make quality products is stand behind them with wonderfully protective warranties. Being the highest-grade treadmill they offer, the Horizon 7.8 AT also comes with premium protection.

There is a lifetime home warranty on both the FeatherLight Folding Frame and 4.0 Continuous-Duty Horsepower Motor. Treadmill parts are covered for 5-years and labor is offered freely for 2-years post-purchase. It’s hard to come by a treadmill with a lifetime warranty on both the motor and deck, which are certainly expensive concerns long-term.

Another brand we’ve found that provides this is Sole Fitness, however their comparable 4.0 CHP F85 treadmill will cost you hundreds more without the aesthetically pleasing benefit of a high-control colored display. The sturdy durability and solid warranty offerings has us excited about the Horizon 7.8 AT treadmill.


Summing Up This Review

Let’s cut to the chase, if you’re a devout runner who has a fitness-focused lifestyle, it’s hard to find home exercise equipment suited for consistent heavy use long-term, that is, until Horizon built the 7.8 AT treadmill.

The fierce power of 4.0 CHP rapid-sync motor paired with the accessible quick precision dials make interval training easily accessible within the comfort of your own home. With its notable warranties, technologically advanced features and high-quality build, the 7.8 AT Treadmill is a perfect match for athletes pursuing a lifetime of movement.
