This allows you to safely work out by focusing entirely on the workout so you don’t fall and safely monitor your heart rate throughout. 

Device Holder

Built into the treadmill is a device holder where you can hold your electronics to keep them safe during your workout. If you are following an exercise video on your iPad, you can safely position the device in the device holder so that you can clearly see the video and the device is safe.

There is also a USB port to keep your device fully charged when you are using it. 

Treadmills that do not have this feature make it difficult to follow workout videos as if you are following on a phone or iPad you may have to try and balance it on the treadmill which makes it incredibly unsafe for yourself and the device. Following on a TV from a distance may cause eye strain, so having the device right in front of you makes it easy to follow. 

The device is held at an angle where you are looking down at it which makes it easier to watch your steps on the treadmill so you don’t misstep and injure yourself. However, the more you become accustomed to looking down at the treadmill may translate into your outdoor running.

Practicing uphill running outside as a beginner can be difficult as it can be hard to find the perfect beginner incline. 

These features make it easy to improve your speed and stamina by practicing at your own pace. The Horizon 7.4 AT treadmill allows you to focus solely on these aspects of training whereas outside, you may become distracted or struggle to train these areas due to business or weather conditions. 

Strong Materials

The treadmill is made out of heavy-duty materials so that you can feel secure and comfortable running using a strong deck and frame. It is important for a treadmill to be made out of strong materials so that you can confidently run without having to worry about damaging the equipment so you can focus solely on your workout. 

An important aspect of any treadmill is the running deck. Without the correct support, you can cause long-term damage to your joints as shockwaves can put pressure on your knees that can cause permanent damage and weakness. The Horizon 7.4 AT treadmill has 3-Zone Variable Response Cushioning that absorbs shock and supports your joints when running. 

These materials help to offer you full support when you are running so that you can make sure that you are taking care of your body when running. If a treadmill isn’t made of strong material and doesn’t have shock-absorbing features, you could potentially cause injuries to yourself. 


The Horizon 7.4 AT treadmill has QuickDial controls that allow you to smoothly change the speed of the incline of your treadmill. The dial is easy to use so you don’t have to stop running to change the speed so you can focus entirely on your workout.

The left dial is used for adjusting the incline while the right dial is used for increasing and decreasing the speed of the treadmill. There are also handles where the dials are so they are within reaching distance when you are running, and there is a handrail to hold if you need extra support when running. 

If you need to stop the treadmill, there is a red button that will emergency stop the treadmill. The button is located by the handrail so it is within reaching distance during your workout.

This allows you to feel secure when working out on the treadmill as you can make it stop instantly whenever you need to. 

Final Thoughts

To conclude, the Horizon 7.4 AT treadmill is a great treadmill to use indoors if you are looking to increase your speed and stamina. The treadmill allows you to concentrate on the areas that you want to improve so that you can feel confident and comfortable when training.

The dials are very easy to use and allow you to increase your speed and incline during your workout when you feel ready.
