Horizon Fitness 7.4 AT Smart Treadmill | Designed for Interactive Training

The Horizon Fitness 7.4 AT Smart Treadmill doesn’t have the same slick touchscreen consoles from NordicTrack and others found on treadmills. However, it still delivers immense value for an affordable entry price from a function, features, and build quality standpoint. All in all, this is a capable runner’s treadmill.

The Horizon 7.4 AT treadmill features an extra-long and wide 22″ x 60″ running deck. Therefore, it is a good option for taller users and is suitable for high-speed sprints. In addition, the 7.4 AT’s 3-Zone variable response cushioning does help to reduce the impact on joints.

The 7.4 AT treadmill is a connected fitness machine. It was designed with interactive training in mind and responded to HIIT and interval training’s ever-growing popularity. The 3.5 CHP motor supports a maximum of 12 mph speed and an incline of 15%. Therefore, it’s ideal for streamed virtual workouts and interval training to support rapid changes in incline and speed.

The Horizon Fitness 7.4 AT Smart treadmill has ten onboard workout programs. These include 5K, calories, custom, HR, distance, fat burn, heart rate, hill climb, manual, and Sprint 8. The 7.4 AT is also Bluetooth-enabled for interactive training. It can connect to multiple devices, allowing you to stream fitness classes through Bluetooth speakers and track your heart rate.

7.4 AT Frame construction

The Horizon Fitness 7.4 AT Smart treadmill features a heavy-duty frame made of steel tubing. The two upright bars that sustain the console are thick, similar to commercial machines. A median bar also connects the two uprights for improved sturdiness; this bar can also support your workout towel.

All the steel parts in the machine’s construction are double-coated with a corrosion-resistant and abrasion-resistant paint finish. The primary color is gray, with the “Horizon” logo in white on both upright bars. Unfortunately, these are the only colors available for this treadmill.

Of course, the Horizon 7.4 AT also has a few ABS parts in its construction. For example, the covers of the side rails, the motor covers, and the dashboard that sustains the console are all made of heavy-duty thermoplastic material.

The fully assembled machine is pretty significant. It is approx—76 ″ (193 cm) long and 37″ (94 cm) wide. Plus, just like other treadmills, it is advisable to assign at least three feet of clearance at the back of the deck and at least two feet of space on each side of the machine for safe usage and ease of access. Thus, the Horizon 7.4 AT may not fit a small room or apartment well.

The treadmill comes equipped with a folding system. It integrates a hydraulic element that assists you with unfolding the deck to prevent it from sustaining damage. With the deck folded up, the length of the machine is reduced to 42″ (107 cm), while its height becomes 71″ (180 cm).

Last but not least, this Horizon Fitness treadmill is weighty. Its net weight is 318 lbs (144 kg). Therefore, transport and assembly require several people. On the other hand, this weight plays a vital role in its overall stability. You can be sure it won’t move or wobble when you run on it.

Deck construction

The Horizon Fitness 7.4 AT smart treadmill has a sturdy deck. Moreover, it has a maximum user weight capacity of up to 325 lbs (147 kg), which is impressive for an only intended home-based machine.

It offers a large running surface of 60″L x 22″ (152 x 56 cm), which means that it should be able to accommodate users up to 6’6 ″ (198 cm) with no problem, allowing a complete range of motion.

The machine comes with a 1.6 mm silicone belt designed to provide a secure grip and minimize it. The internal rollers are pretty significant. The front one is 60 mm (2.3″) in diameter, while the rear one is 46 mm (1.8″).

These rollers are tapered to provide better traction and prolong the belt’s lifespan. The rollers also integrate industrial-grade, sealed ball bearings for a smooth motion.

Like other Horizon Fitness treadmills, the 7.4 AT model features a 3-zone variable deck cushioning. The front section is the impact area with more cushioning to alleviate each foot strike’s shock. In addition, the center section offers moderate cushioning for a better transition, while the rear section is harder to promote a better push-off.

7.4 AT Incline and step-up height

The Horizon Fitness 7.4 AT smart treadmill has a motorized incline system. Therefore, the machine can adjust the incline automatically, depending on the user program. You can also change the slope manually while walking or running from the built-in controls.

The unit’s incline system consists of a small motor and a lift integrated at the deck’s front. The motor enables the lift to elevate the deck’s front section as you adjust the incline or the console adjusts the slope.

The machine makes available an incline range between 0% and 15%. The incline is adjustable in increments of 0.5% from the controls integrated into the console or the left upright grip. However, the console also has quick incline selection buttons on the left for the 0, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, and 15 incline positions.

The step-up deck height is approx—9″ (22 cm); however, the deck’s front gains a few inches in size with the incline set to maximum. Therefore, it is advisable to use the machine in a room with a ceiling that is at least 15″ – 20″ (38 – 51 cm) higher than the height of the tallest user.

Drive motor and speed range

The Horizon Fitness 7.4 AT smart treadmill comes equipped with a heavy-duty Johnson 3.5 CHP motor designed to withstand prolonged workouts at maximum speeds without losing performance or overheating. It integrates a small flywheel for improved stability as well.

The machine’s drive system features RapidSyncTM technology, which ensures no lag between speed and incline adjustments. It also responds very fast to any command, so you’ll never fall out of step during your workouts.

This Horizon Fitness treadmill offers a speed range between 0.5 and 12 MPH. The speed adjustment increments are 0.1 MPH. Therefore, it results in a smooth transition from one-speed level to another, giving you plenty of time to adjust your pace.

The unit’s speed can gradually adjust from the console arrow keys or the +/- keys incorporated into the right vertical grip. However, the console also makes quick selection speed controls available, just as for the incline. In addition, the console’s right bottom section has a tiny keypad with quick speed controls from 1 to 12 MPH.

7.4 AT console

The Horizon Fitness 7.4 AT smart treadmill features a multi-function console. To begin with, it has two displays, one LCD-type and the other LED-type. They indicate time, distance, pulse, burned calories, speed, and incline.

However, the top LCD, which is more extensive, also shows the program’s grid and several other workout metrics. Speed and distance are by default set to English units, but metric units are also available.

The console can also read your pulse if you hold on to the sensors integrated into the treadmill’s vertical grips, but it can also communicate with a Polar Bluetooth wireless HR chest strap. However, this accessory does not come included with the machine.

The console has ten built-in workout modes. Each workout mode has a quick access key. Some of these workout modes have multiple settings or difficulty levels. The ten workout modes are Manual, Hill Climb, 5K, Fat Burn, Custom, Distance, Calories, Custom Heart Rate, Target Heart Rate, and Sprint 8.

Sprint 8 is the standout workout program on the 7.4 AT treadmill. Each 20-minute sprint-based interval training workout contains just 4 minutes of high-intensity exercise. These workouts are only 20 minutes long and allow anyone to add activity to their busy day. Sprint 8 primarily benefits from the 7.4 AT’s rapid speed adjustment capability.

All these offer a wide array of workout possibilities; some adjust only the speed. In contrast, others automatically adjust both the machine’s speed and incline, depending on each segment.

You can connect your smartphone or tablet to it via cable or Bluetooth to play your music through the integrated speakers for superior sound quality.

The cooling fan is at the bottom of the console. The integrated fan is not extremely large but does provide some cooling if needed. The two device holders consist of two small shelves, one under the LCD and above. They can provide support for your tablet or smartphone if required.

The two-bottle (or other accessories) compartments are pretty large as well. They are on each side of the console. And finally, the USB port only serves as a charging port for your device. It does not allow workout data transfer on a USB stick.

  1. Looking through the Horizon 7.4 AT treadmill’s pictures, I can tell that it is a great treadmill. Reading this article thoroughly, I got to find out that not only is it a great treadmill, but it also has lots of amazing features and some spectacular designs. Coming with the wireless HR chest strap would have been the cherry on the icing. 

    I click the Amazon link (for this treadmill) you provided to know the price, turns out they are out of stock. Well, I will try to check elsewhere for the price.

    Thanks for this review on this one of a kind treadmill.

  2. I’m not very big on exercising because I feel it’s too stressful. However, the treadmill seems really fun and easy. I’ve been wondering if it just looks easy because I’m not on it. I’ve never been on a treadmill, but I think I’ll purchase this Horizon 7.4 AT treadmill. It’s affordable and looks really good.
