The New Horizon 7.4 AT Treadmill – Review of a Solid Machine

The Horizon 7.4 AT takes your workout to the next level. It’s one of the newest additions to the popular company's treadmill lineup, part of the Studio Series that bridges the gap between the entry level models and the top of the line Elite Series.

Though similar to the base model 7.0, it features a motor with RapidSync Drive System that makes it particularly tailored for interval training. It’s still simple enough for beginners to use yet adds many nice features that allow for a more advanced workout.

Let's take a closer look and see what the 7.4 AT is all about...

The Buzz

Horizon 7.4AT - Tablet or Smart Phone With Free Workout App

The Horizon 7.4 AT has received very positive reviews thus far from customers who are impressed with the smooth function and ease of use. As this is a mid-range model, it’s a step up in price from the standard models yet still offers an affordable alternative to higher end brands like Life Fitness and Precor.

Despite the competitive pricing, all of the treadmills from Horizon Fitness have the quality and features that other brands do. All of their machines are solidly built, yet easy to maneuver and store so they are an ideal addition to any home gym.  

What sets the 7.4 AT apart from the other models, including the base 7.0 AT, is the RapidSync Drive System.  

The 3.5 continuous-duty horsepower motor and 500 lb. thrust incline motor combine to create the most responsive drive system available in a treadmill, allowing for faster changes and a smoother, more efficient run that makes it ideal for interval training.

It has a max user weight of 325 lbs., speeds up to 12 mph and an extra large 22" x 60" runner's deck.  Like all of Horizon’s treadmills, the deck is built with 3-Zone Variable Response Cushioning to give you full support throughout your entire stride.

With 33% faster incline and speed changes, the 7.4 AT lets more advanced runners stay in step with their interval training classes.

Amazingly, despite all of its advanced features and capabilities, the Horizon 7.4 AT is under $1,500 on sale, which is surprisingly affordable compared to other brands with similar offerings.

Along with all of the mechanical and comfort features, the 7.4 AT also offers some great technology, including the free training app, which you can access via Bluetooth on your tablet or smart phone.  

A built-in device holder keeps your tablet or phone easily visible throughout your entire workout and a rapid-charge USB port ensures that your device doesn’t lose power even during the longest workout.

You can maximize your interval training with the free Sprint 8 high-intensity interval training workout program, an easy to use 20 minute program that is proven to burn up to 27% body weight in just 8 weeks.

With the free Pro app, also available on the top-of-the-line 7.8 AT, you can also connect your tablet and Bluetooth heart rate monitor and share your stats with your favorite apps such as Fitbit so you can keep track of all your data in one place.

As with all Horizon treadmills, the 7.4 AT comes with a generous lifetime warranty on the frame and motor as well as a 5 year parts and 2 year labor warranty.  This means you can enjoy your investment for years to come, worry free.  

All in all, we really like the 7.4 AT treadmill and feel it's definitely worth considering.  Compare it to similar models from NordicTrack and ProForm and we think you’ll appreciate the difference too.

How Does the 7.4 AT Compare to the Rest of the Horizon Lineup?

You really can't go wrong with any of the Horizon treadmills.  They are all well built and give you plenty of value for the money.  So it comes down to deciding whether you want an entry level, mid level or top of the line model.

Let's take a look at the whole line to see how they compare...

GO Series


The T101 is probably the most popular model that Horizon offers, as it is very competitively priced yet gives you a lot of capability.

There's a 20" x 55" runner's deck, 10 mph speed, capable 2.5 CHP motor and 10 levels of incline capability. It has a maximum user weight of 300 lbs.


Stepping up there's the T202 treadmill. You get a larger 20" x 60" runner's deck, 12 mph speed capability, stronger 2.75 CHP motor and 12 levels of incline to choose from.  There's a higher maximum weight capacity as well...up to 325 lbs.


Horizon’s introduction to interval training, the T303 includes many of the same specs as the T202 along with a free phone/tablet Pro App as well as Hill Climb, My First 5K and Heart Rate programs in addition to the regular program offerings.   Also includes an expanded 3 year warranty on parts.

Adventure Series

Adventure 3

The Adventure 3 is sort of a hybrid of the T101 and T202 treadmills.  It shares the motor, max user weight capacity and running deck size of the T101 but has the speed and incline capability of the T202 model.  

However, it doesn't have Bluetooth capability, but gives you ViaFit workout tracking and Passport HD video capability, two exclusive Horizon Fitness features.

Studio Series

7.0 AT

The Horizon 7.0 AT is a step up from the Adventure 3, and the first model in the Studio Series.  

You get the Bluetooth capability and free workout app that the T202 has, with more capability and functionality.

7.4 AT

As mentioned above, the 7.4 AT is designed specifically with interval training in mind, combining all of the features of the 7.0 with a RapidSync Drive System that allows for smooth transitioning.  The built in Bluetooth capability and free Sprint 8 high-intensity interval training workout program let you get the most out of your workout without spending a fortune.

7.8 AT

The top step of the Studio Series, the 7.8 AT gives you all of the features of the 7.0 and 7.4, including a spacious and comfortable deck space and Bluetooth capability.  It takes your interval training to the next level with exclusive QuickDial controls and one-touch Interval Keys.

Elite Series

These are considered the top of the line models, closer to what you might find at the health club...more durable, heavier, more capable of handling intense workouts.

There's the Elite T5, T7 and T9, with maximum user weights of 350 lbs., incline capability to 15%, running decks up to 22" x 60", motors up to 3.25 CHP, the strongest warranties and up to 42 built in workout programs.

So the 7.4 AT is going to be an affordable mid level treadmill, better than what the GO Series has to offer but not quite as durable as the Elite Series.

Horizon 7.4 AT Review - Bottom Line

There’s a lot to love about the new Horizon 7.4 AT and here at Treadmill Talk we’re impressed. We like the Bluetooth capability and free workout app that allows you to control your machine and track all of your results.

We especially like the competitive price, which is hundreds less than similar models.  

When you consider the many features including good incline, solid cushioning, diverse workouts and lots of extras, it’s well worth the cost.
