Horizon 7.4 AT Treadmill Construction

The 7.4 AT has a steel frame and weighs 318 pounds. The quiet treadmill is sturdy and feels solid even at high speeds. Horizon warranties the motor and frame on all treadmills for life, including the 7.4AT.

Thanks to Bluetooth, you may use this treadmill with numerous running applications. The console’s design is not as intuitive as others. But it works, and the digital bottom boxes provide exercise information as you go.

Not only does the Horizon 7.4 AT fold into a V when not in use, but it also reduces its size to 42″L x 37″ W x 71″H, saving you space. 

Its tapered rollers are 2.4 inches and 1.8 inches.


The 3.5 horsepower continuous-duty motor and 22″W x 60″L deck give lots of power and area.

The motor is equipped with Horizon’s ingenious Rapid Sync Technology, enabling it to speed up and slow down more quickly than a regular treadmill.

Bigger belt rollers employed for improved performance are especially beneficial for a lifetime since the treadmill maintains the same peak speed of 12 mph and maximum inclination of 15 percent.

The Horizon 7.4 AT has a quiet motor, and the belt makes more noise comparatively when you walk or run. So walking is more silent than running and doesn’t make much difference with the incline.

The excellent motor mechanism allows the machine to run smoothly at any gradient and can be utilized well for interval training.

Speed & Incline

Horizon 7.4 AT has a speed ranging from 0 to a maximum of 12 mph and incline from 0% to 15%.

When doing hard hill training, the 15% gradient is enough to work your glutes and hamstrings. The slope range also offers various training variables at different incline levels.

The QuickDial Controls, located on the treadmill’s grips, are accessible for the users to roll up or down with their thumbs. They are an excellent feature that makes adjusting the elevation and speed of the machine much more uncomplicated. These dials seem more natural and responsive than the console’s touch buttons.

The QuickDial controls and manual speed changes are smooth and have minimal jerkiness.

The speed & incline, along with QuickDial controls, make it ideal for streaming exercise courses, decreasing joint injuries, sprinting, and walking. The 7.4 AT boasts large rollers that reduce belt tension, enable a smooth glide, and excellent interval training.

Console & Display

If you use a tablet on the higher shelf, it blocks the LCD screen, so you can only view your metrics through the bottom boxes. No need for two display panels, but it works.

This combination of features makes the Horizon 7.4 AT an excellent treadmill for rigorous training or leisurely strolling. You may use your favorite app with the 7.4 AT to train in any way.

For those seeking a high-tech and engaging display, the Horizon 7.4 AT falls short.

But we still can’t move it much due to its weight of 318 lbs.

Three zones of variable response cushioning give different amounts of shock absorption in three other areas of the running surface that vary from runner to runner, depending on the stride length.

The cushioning decreases impact by 30% compared to road jogging, which is tremendous! The 7.4 AT’s cushioned feel is impressive.

You may also avoid injuries with the ortho-lite belt’s gentle feel. The 7.4 AT is a beautiful alternative for walkers because of the extra cushioning for people with joint troubles or mobility concerns. Indoor walking on a cushioned floor may assist improve general mobility.

This treadmill was designed to work with third-party workout applications mainly.

Rather than limiting users to a specific set of programming, this can incorporate a wide variety of online training programs, such as Studio, Daily Burn, Aaptiv, and Treo, into a single device.
