Horizon 7.4 AT Review (2024) – Peloton, Zwift, HIIT, & More!

Dimensions/Storability

The Horizon 7.4 AT Treadmill is pretty much the same size as the 7.8 AT. Its dimensions are 76” L x 37” W x 63” H. It folds up to be just 42” L, so it almost cuts the amount of floor space it takes up in half when the deck is folded up.

The deck has a lift assist, which kicks in when you lift the back end of the deck. Once you push it up towards the console, the deck locks in place. When unlocked, it will slowly lower to the floor on its own.

Although the 7.4 AT is a large and heavy treadmill at 318 lbs, the folding mechanism is convenient to help save some space. Also, when folded, this treadmill can be moved. You need to tip back the deck when folded to engage the transport wheels. With its size, we don’t recommend moving it often; it’s best to have a designated space for it to stay.

For floor space, it’s a good idea to consider the overall dimensions and add a few feet surrounding the treadmill, especially behind the deck, to ensure that you’ll be able to use it safely.

The step-up height of the deck should be around 9” high from the floor up to the side rails when the deck is flat. With this deck height, we recommend having at least an 8.5 ft high ceiling if you’re a 6’0” ft tall runner. You can use these guidelines to determine the proper ceiling height you’ll need for the 7.4 AT.

Onboard Workouts & Apps

The Horizon 7.4 AT Treadmill has a lower-tech design than other treadmills on the market. Most treadmills, like the NordicTrack 1750 and Sole F80, have touch screens with streaming content. Instead, the 7.4 AT should feel more like using a commercial treadmill.

Everything I’m going to talk about in this Horizon 7.4 AT review is included on the console. You don’t have to pay an additional subscription fee to access any of the content.

Onboard Workouts

The workout programs on the 7.4 AT are pretty standard. They include manual mode, 5k, calorie, custom, custom heart rate, distance, fat burn, heart rate, and hill climb. You can customize the distance and time and set intervals in these workout programs. There are also five profiles for each person to save their weight and preferences, as well as a guest profile.

The programs are displayed by different icons on the console. These aren’t buttons, but there is a small light next to each that lights up when you have a program selected.

Sprint 8, which is an interval training program, is also integrated into the touch screen. This is especially helpful and nice to have if you want to do interval training on the 7.4 AT. There are 20 different levels of difficulty to choose from, and the treadmill should automatically adjust the preset speeds and inclines during the workouts.

Although the console doesn’t have streaming content, you can use your phone or tablet to stream whatever you want. You can also just put the 7.4 AT in front of your TV.

Console

The Horizon 7.4 AT Treadmill has an 8.25” LCD screen and a 16-digit alphanumeric LED screen. The top display isn’t full-color like the 7.8 AT, but you should be able to see your workout metrics and the layout of each workout program in a graph, clearly. You should be able to get feedback for your estimated calories burned, distance, heart rate, incline, speed, and time, too.

Overall, the console looks pretty dated compared to other treadmill models with more integrated tech features and touch screens. It should be functional, though. There are plenty of buttons to change the speed and incline. The numbered adjustment buttons on the right and left of the console allow you to easily jump back and forth between specific speed and incline settings.

I prefer using the blue roller dials that are on the front handles. The right is for adjusting the speed, and the left is for the incline range. You just roll these forward and back to adjust. They adjust the speed by 0.1 mph and the incline by 0.5%.

The middle, round program button is fairly easy to use on the 7.8 AT. It’s the same on both of these treadmills. I think it’d be better if the icons of the workout programs were actual buttons, but this works just fine.
The 7.4 AT Treadmill is Bluetooth-enabled and can be used with apps like Peloton and Zwift. The speakers are Bluetooth-enabled to pair with your device to play your own content through them. They should offer enough of a volume range, too.

You can also connect the Bluetooth heart rate monitor chest strap to the console to read your heart rate on the display. The monitor is included with the Horizon 7.4 AT. There are also pulse grips on the front handles, but the monitor is more beneficial for accurate heart rate tracking.

The fan looks to be the same on the 7.4 AT as it is on the 7.8 AT. It most likely is. The fan on the 7.8 AT is positioned a little too low for taller people and it isn’t the most powered treadmill fan. I’m about 5’1” and it hits my face. You might want to plan on plugging in your own if you sweat a lot while using the 7.4 AT.

The 7.4 AT doesn’t have a storage tray below the console, but it doesn’t need one. There are two cup holders for your standard water bottle and two device racks to place your phone or tablet. One is above the LCD screen and the other is directly below it. This is nice to be able to watch whatever you want from your own device while using this treadmill.

Build Quality

Getting into the construction and build quality of this Horizon Fitness 7.4 AT Treadmill review, we anticipate this midrange treadmill to perform similarly to the premium 7.8 AT. It has a lot of the same features and construction. In our testing, we have found the 7.8 AT to be a durable, heavy-duty folding treadmill, so we expect the 7.4 to be as well.

A good indication that it’s well built is the 350 lb weight limit it is rated with. This is a good weight limit for home treadmills. People up to this weight should be able to use this treadmill.

Frame

The Horizon 7.4 AT has a steel frame that supports the deck, two steel uprights, and steel handles. There is also a steel crossbar that’s mounted between the uprights, which helps to add stability and support to the machine.

The 7.8 AT has a steel crossbar too, so I’m anticipating the 7.4 AT to be very sturdy to use. The console and frame should stay steady while running.

The side handles extend on either side of the deck to be within reach while you’re using the treadmill. The front handles are vertical and should be easy to grab, too.

Motor

The Horizon 7.4 AT has a 3.5 HP motor. This is a good motor size for heavy training. If you are training for an event or hoping to log a lot of miles, the 7.4 AT should be good for that. It’s also a great option if there are multiple people in your home who want to use the treadmill.

The 7.4 AT goes up to 12 mph and has a 15% incline. This is the same as the other treadmills in Horizon’s Studio Series. The max speed is a 5-minute mile pace. This speed is typical for midrange and premium home treadmills. The incline range should offer plenty of variety to vary your training, too. There isn’t a decline feature.

One aspect that we’ve tested on the other Horizon Treadmills that we have in our studio is the motor responsiveness. This is the rate at which the speed adjusts from 1 mph up to the max speed. The Horizon 7.8 AT is one of the quickest adjusting treadmills that we’ve tested. It only takes around 19 seconds to go from 1 mph to 12 mph.

Although the 7.4 AT is slightly less powered, I assume the motor is still responsive to adjust quickly and comparably to the 7.8 AT. Compared to the NordicTrack 1750, ProForm Pro 2000, and Sole F80, I am betting the 7.4 AT adjusts more quickly between the speeds.

I also anticipate the motor to be quiet. Horizon Treadmills are some of the quietest that we’ve tested. We’ll be sure to test this and update our review once we get the 7.4 AT Treadmill in our studio though.

Deck

The deck is 22” wide and 60” long. This is the largest deck size we’ve seen on folding treadmills. It should offer plenty of space for all running strides and fitness levels. This deck size means this isn’t a compact treadmill though, so you’ll need to factor that in to ensure it fits in your home.

The deck appears to be the same, or at least very similar to the 7.8 AT. It features the same 3-Zone Variable Response Cushioning. There are said to be three different zones of cushioning in the deck. While you most likely won’t notice these different zones, the overall feel of the deck underfoot should be soft and shock-absorbing with each footfall.

Horizon overall is somewhere in the middle of the road when it comes to deck cushioning. NordicTrack tends to offer the most shock absorption to feel very soft underfoot, while Sole Treadmills feel firmer and more comparable to road running.

I think the 7.4 AT should be comfortable for most fitness enthusiasts and runners.
The build quality overall is very comparable to Horizon’s premium model, so I anticipate that users should not only be able to get a lot of use out of this treadmill but that it should feel very stable and well-powered.

Warranty

Horizon Fitness includes a lifetime frame and motor warranty with the purchase of the 7.4 AT. We really appreciate Horizon backing up its treadmills with this warranty. It helps to instill confidence in the quality. The 7.4 AT also comes with a 5-year parts and 2-year labor warranty. This warranty package overall is a bit more than what we see from other brands.

Should You Buy the Horizon 7.4 AT

Overall, the Horizon 7.4 AT Treadmill has everything we look for in a high-quality midrange model. It has a heavy-duty design, it’s made with quality materials, and it shares a lot of similarities to its step-up model, the 7.8 AT, which we have been testing for a few years now.

If you’re looking for a simple-to-use treadmill, the 7.4 AT is a good option. It comes with standard workout programs and the Sprint 8 training program, as well as the ability to place your device on the console to stream your own content. If you don’t want to subscribe to a subscription training platform, the 7.4 AT Treadmill is a great pick, too.

We assume the 3.5 HP motor is quick to adjust, so we highly recommend checking it out if you love HIIT training on a treadmill. The deck is large enough to support all stride lengths and people up to 350 lbs., plus it folds up when you’re finished. Although this is a large treadmill, it has a space-saving design, and it should handle a lot of use.
