The Horizon 7.8 AT has a wide-ranging speed from 0.5 mph all the way to 12mph for great workout flexibility and capability of the treadmill. This machine is sure to challenge the runner to greater speeds and endurance through its speed.

On the other hand, the 7.4 AT from the same brand has a similar top speed of 12mph.

One thing to understand about both of these treadmills is that they are designed to walk, jog, and run. For walking, the ideal speed is 4mph, and more than 6mph is a great speed for your running workout. Between 4 to 6 mph is the jogging speed.


Both of these treadmills have the same incline range with a maximum incline of 15%. A 15% incline is not a general incline offered by most brands, but both these treadmills have more to offer.

A 40% incline is an ideal workout requirement to boost your routine to greater endurance levels. More calories are burnt on a greater incline, and at the same time, you can target a wider range of muscles.

Another technology known as power incline gives you the ability to adjust your incline with a single touch on the console. This is an easy way to make your workout intense and efficient.

Running Area

Both treadmills stand toe-to-toe in this department as well, with a large running area of 22” x 60”. The average length of a treadmill is usually 50,” but these treadmills are designed for runners and walkers alike.

Due to this, the 7.8 AT and 7.4 AT from the Horizon roster have expanded the running area for runners at a length of 60”.

However, this expansive running area comes at the cost of a larger space in your room since large treadmills will take up a large space in your room.

But since the treadmills are foldable, you are saved the burden of giving up space in your apartment.

Weight Capacity

The Horizon 7.8 AT has more maximum user weight capacity than the Horizon 7.4 AT. The difference is a good 25 lbs as the 7.8 AT stands at 350 lbs while the 7.4 AT can bear a nominal 325 lbs.

The 7.8 AT is on the higher side of treadmills as the treadmills’ user weight starts from 250 lbs right up to 400 lbs.


Both the treadmills can be folded as the 7.4 AT has a FeatherLight folding and the 7.8 AT has a SpaceSaver frame.

The FeatherLight folding system is a hydraulic folding mechanism that helps you to store the treadmill effortlessly.

What makes the FeatherLight folding system stand out from the other treadmills is that it can be folded very compactly even after your daily use.

Built-In Program

The 7.8 AT and the 7.4 AT house the Sprint 8 program, which is much underrated. It is a 20-minute, highly intense workout program to burn fat efficiently and improve your cardio levels even during your busy schedule.

It includes sprints and much more to help you even lose weight and burn a lot of calories. This increases energy levels and keeps your body immune.

Quick Summary of Horizon 7.8 AT Treadmill

The 7.8 AT does more than impress with its highly advanced built-in Sprint 8 program, a high-intensity weight-loss, fat-burning, cardio-enhancing, and energy-boosting program.

This, of course, is matched with the unparalleled robust structure of the 7.8 AT, which is also powered by a strong 4.0 CHP motor.

This heavy-duty motor delivers a maximum speed of 12 mph, which is ideal for runners to walkers alike.

Strong grips and the high-quality body of the machine are aesthetically designed with magnificent capabilities. Bluetooth compatibility can be utilized to monitor pulses and track your workout in the console.

But it can also be used to enjoy music while you carry on with your high-intensity workout on the Horizon 7.8 AT treadmill.

Comfort is given a great deal of attention by providing a cushioning system that protects your joints and bones from injury. This dedication to safety is appreciated by its patrons as the machine becomes a very convenient and safe one to use.

A Quick Summary of Horizon 7.4 AT Treadmill

The Horizon 7.4 AT is also a huge step from its previous models, widely admired by gym professionals. It has a wide deck designed for running professionals to run on it with all their stride length.

Due to the long deck, walkers and joggers can use the machine with great ease. The 325 lbs user capacity is more than enough for its 3.5 CHP motor to provide a speed ranging from 0.5 to a maximum of 12mph speed on the treadmill.

It also has the Sprint 8 program, a HIIT program meant to increase your cardiovascular endurance and keep your body in great shape.

Its grips are powerful, but they can also be used to trigger various controls in the machine to ramp up your workout. One of the adjustable features in the treadmill is its incline, which can be increased from zero to a good 15% incline without any decline.

It also has a FeatherLight storage system, which reduces the treadmill’s footprint and saves space in your room or apartment.

An LCD, along with Bluetooth speakers, allows you to monitor your pulse and workout routine apart from enjoying your favorite music while doing your best workouts.
