The 7.8 AT is Horizon’s flagship treadmill in the STUDIO series. It boasts a few additional features and enhancements compared to its sibling models. In this review, we are going to look at Horizon’s 7.8 AT treadmill to help you decide if it suits your needs and let you know the pros and cons.
The 7.8 AT comes with a 9.3-inch full-color display screen. In contrast to the basic LCD screen on the 7.4 AT, it presents all your important stats and settings in high-resolution format with color. The new color screen is a great addition, but it is still basic and nowhere near to an HD touchscreen display. If you want to interact with training apps using your smart device (i.e a tablet) the 7.8 AT has a shelf above its display that allows you to place your tablet.

The 7.8 AT is designed to provide users with challenging workouts that push their limits on a large solid deck. This powerful treadmill is equipped with a 4.0 CHP motor and can support users up to 375 pounds. This makes it a good option for people looking for a treadmill for heavy people. Additionally, it has a top speed of 12 MPH and a maximum incline of 15%.
Another convenient feature we like is its foldable design, making it an ideal option for runners with limited space. It has a reasonable footprint, measuring 76L x 37W x 64H inches. To monitor your heart rate, there are contact grip sensors on the handlebars, and for more accurate readings – and more comfortable use — the treadmill console is compatible with wireless chest straps. Making it even more appealing, Horizon has included a Bluetooth wireless chest strap in the box.
What We Like About the Horizon 7.8 AT:
Strong Motor: Comes with a 4.0 CHP motor which is typically found on higher-end, commercial-grade treadmills. The motor provides plenty of power for high-intensity workouts, can handle heavy usage, and it comes with a lifetime warranty. The 7.8 AT’s motor utilizes Rapid Sync technology, specifically engineered for High-Intensity Interval Training (HIIT). This motor allows for faster acceleration and deceleration in comparison to other models. When combined with 7.8 AT’s 375 lbs. weight capacity it makes this treadmill also great for overweight people.
Multiple 3rd-Party Apps: It does not have a touchscreen, but this treadmill is smart enough to sync with popular apps such as Zwift, Peloton, AtZone, and more. Some of these apps can control the incline and speed, you can check our page about compatible apps with Horizon AT Series treadmills.

Large running deck: The 22″ x 60″ running belt offers plenty of room for taller and heavier runners and is wider than some of the treadmills in its price range.
Heart Rate Monitoring: The 7.8 AT treadmill from Horizon Fitness comes with a convenient Bluetooth wireless chest strap for monitoring heart rate during training. Additionally, the treadmill also features built-in contact grip sensors on the handlebars. The inclusion of the chest strap in the box makes this treadmill even more appealing.

The Horizon 7.8 AT Treadmill for HIIT Lovers
HIIT workouts on this treadmill help your body in many ways. They can help you breathe better, use sugar better, burn more fat, and get a stronger heart. Plus, because HIIT is tough, workouts are shorter. You get your exercise done quickly and have more time for the rest of your day! The Horizon 7.8 AT is a top pick for people who love fast and powerful workouts, like HIIT (High-Intensity Interval Training).
Here’s why it’s a winner as the best treadmill for HIIT training:
First off, it’s super easy to use. When you’re doing a HIIT workout, which mixes up fast running with slower rest times, the Horizon 7.8 AT changes speeds for you. It has a bunch of built-in workouts that change from really easy to super tough. This means you can focus on your workout without messing with buttons. However, it also has quick controls on the handlebars, so you can change incline and speed very easily if you like more control.
This treadmill is also strong and quick, but it’s not loud, so it won’t bug you or others when it’s running fast. It’s built low to the ground, making it a breeze to hop on and start exercising.
What’s cool is you don’t need to stick to just what’s on the treadmill. It works with different 3rd-party fitness apps. You can use other apps for new workouts or to make your own, and you don’t have to pay extra each month to use them.
The Horizon 7.8 AT isn’t just about the tough stuff. It’s also friendly for when you want to just chill in a slow pace. It doesn’t have a fancy screen, but it does have spots to put your tablet or phone. So, you can watch shows or use other apps that you like while you work out.
Bottom Line:
Overall, the 7.8 AT treadmill is a very solid choice. It is a well-built model with a strong motor and high user-weight capacity, making it a compelling option for those in need of a durable treadmill.
Additionally, it comes with a wireless heart rate monitor included, providing added value to your purchase. If you are not looking for a treadmill with a fancy console loaded with entertainment features, the 7.8 AT is a great option for you. However, if budget is a concern, the 7.4 AT model might be a more cost-effective option to consider.

Hey there! So, I need a treadmill because of the bad weather and my new job’s schedule. I’ve narrowed my choices down to the Horizon 7.8 and the Sole F80, both pretty similar in price.
I’m kinda leaning towards the Horizon, but I gotta make sure it’s quiet since I’ll be using it super early or really late at night⏰. Anyone know how loud it gets at 10+ mph? Do I need a special mat or something to keep the noise down? Or is F80 better for late night runs?
I have the 7.4 AT, the motor stays pretty quiet at high speeds, but you’ll still hear the sound of your footsteps, of course which which might be annoying for people living below. There are mats to reduce the noise but I haven’t tried them myself. Hope it helps.
