Our Rating

Rating: 93.5/100.

The 7.4 AT treadmill is a connected fitness machine. It was designed with interactive training in mind and also responds to the ever-growing popularity of HIIT and interval training. This is seen in the design, for example, with the one-touch keys and handlebar toggles which simplify speed and incline changes. It’s also seen across the performance components such as the powerful motor, which supports smooth speed and incline alterations. These features complement the onboard Sprint 8 program, Horizon’s 20-minute high-intensity interval training workout. They also allow you to keep pace with whatever fitness streaming app you choose. The 7.4 AT is designed to work with a variety of fitness apps. Whether you want to track your stats with a wireless chest strap and push this data over to Fitbit, or stream a Peloton treadmill routine through the integrated speakers, the 7.4 AT allows you to build a connected training regime on your own terms.

Horizon’s confidence in the durability of this treadmill is clearly illustrated by its lifetime frame and motor warranty. And the 3-year warranty on parts and 2 years on labor isn’t a bad deal either. With all its features and this generous warranty considered, the 7.4 AT’s $1,599 price tag is impressive.

Horizon Fitness excels when it comes to combining build quality and value. Rather than adding in fancy touchscreens or creating a dedicated brand app, Horizon has instead channeled its efforts into building high-quality treadmills that work with most fitness apps. This puts the power in the user’s hands. You can choose what training apps you use, how you track your stats, and what screen you bring to the table. Having to bring your own tablet to use as a screen may seem like a downside, but it’s a move that keeps costs down. As well as ensuring the 7.4 AT delivers a connected workout experience, Horizon has also made sure the treadmill can keep up with interval and HIIT workouts. Dig deeper into the details of the Horizon 7.4 AT treadmill’s workout programs, features and buyer protections below.

Workout Programs

The Horizon 7.4 AT treadmill has 10 onboard workout programs. These include 5K, calorie, custom, custom HR, distance, fat burn, heart rate, hill climb, manual, and Sprint 8. This isn’t that many, but the variety is inclusive enough for most trainees. Sprint 8 is the standout workout program on this machine. Each 20-minute sprint-based interval training workout contains just 4 minutes of high-intensity exercise. At just 20 minutes long, these workouts allow anyone to pack exercise into their busy day. Sprint 8 especially benefits from the 7.4 AT’s rapid speed adjustment capability.

As well as offering these onboard workouts, the 7.4 AT is Bluetooth-enabled for interactive training. It can connect to multiple devices, allowing you to stream fitness classes through the Bluetooth speakers and track your heart rate. Horizon offers discounts on the top fitness apps such as Studio, Aaptiv and Daily Burn to get you started. You can also use the free AFG Pro Fitness app to control your treadmill via your tablet, monitor your workout, track your progress, and view your workout history. The third-party apps such as Peloton or Studio don’t interface with the treadmill, so they won’t record your progress within the app. You will be marked as active in the class, but it will show that you are not making any progress. That’s why it’s useful to use the Pro app alongside the streaming apps for stats tracking.

It’s worth noting that when you stream workouts from apps such as Peloton or Studio with the Horizon 7.4 AT, your incline and speed won’t be automatically adjusted by the app. Although this happens on some trainers such as NordicTrack or ProForm machines via iFit, the Horizon 7.4 AT can’t do this. When streaming a workout video, you will have to manually adjust your incline and speed throughout the program. This could be seen as less immersive, as your personal trainer doesn’t control your machine for you. But with the user-friendly design features on the 7.4 AT (such as the one-touch keys and handlebar controls), it’s actually super easy to change your incline and speed without disrupting your workout.

Horizon 7.4 AT Features

The Horizon 7.4 AT treadmill features an extra-long 22″ x 60″ running deck. This makes it a good option for taller trainees, and suitable for high-speed sprinting. Although the deck cushioning is not adjustable as it is on some treadmill brands such as NordicTrack, the 7.4 AT’s 3-Zone variable response cushioning does help to reduce impact on joints. The 3.5 CHP motor supports a maximum speed of 12 mph, and an incline up to 15%. As mentioned, this is ideal for keeping pace with streamed virtual workouts and interval training as it can support speedy changes in incline and speed.

Bluetooth connectivity allows you to pair your wireless heart-rate monitor to the treadmill, and connect your smartphone to stream music or workouts through the speakers. There’s also an audio in/out jack and tablet holder to dock your devices. Although the 7.4 AT doesn’t have a flashy touchscreen, its 16-digit alphanumeric LED and 8.25″ LCD put all your essential workout data in front of you. This includes calories, distance, heart rate, incline, speed, and time. You can also use the free AFG Pro Fitness app to control your treadmill via your tablet and monitor your workout from there. You can then push these workout stats to other apps such as Fitbit and Under Armour.

The 7.4 AT features a FeatherLight folding design and transport wheels for easy folding and storing after workouts. Its sturdy frame can support up to 325 lbs.

Warranty & Guarantee

The Horizon 7.4 AT treadmill warranty includes:

– Frame: Lifetime

– Motor: Lifetime 

– Parts & Electronics: 3 years 

– Labor: 2 years

The Horizon 7.4 AT is a solid treadmill for runners who appreciate connected fitness. If you have a budget of around $1,599 and prioritize quality and durability over flashy tech (such as large built-in touchscreens), the 7.4 AT is a good match for you. We love that you can choose which interactive training programs and stats tracking apps to use with the machine. The addition of the onboard Sprint 8 program is also a big plus, as this means you always have this at your fingertips even if you don’t have a smartphone or tablet on hand.

If you like everything about this model, you should also consider the Horizon 7.8 AT. It has everything the 7.4 AT has and more. This includes a more powerful motor, rolling controls (much like those found on the Peloton Tread), and a 9.3” color display. These features could be worth the few hundreds of dollars more when it comes to interactive training.
