How long will the Horizon 7.8AT last?

No doubt about it, the Horizon 7.8AT was built to last through years of robust workouts and even has a hefty weight of 330 lbs. when fully assembled. With a max user weight of 375 lbs., this treadmill is built for heavier folks and is a mighty machine indeed! Of course, it does not hurt that the 7.8AT also carries a respectable lifetime warranty on both the frame and the motor, which eases the mind of anyone looking to invest in this piece of exercise equipment. Also, at the time of purchase, the consumer is offered warranty boosts on both labor and warranty which is a stellar gesture from the manufacturer.

Brief Overview

The Horizon 7.8AT is our Second Place Best Buy Winner in the $1,500 - $3,000 price range. It is a hardy machine that offers folding action for space saving options and is chock full of quality components meant to lift exercise sessions to the extreme. Purchase of the 7.8AT also includes the use of the Sprint 8 program which touts better results than typical HIIT programs and keeps training sessions challenging to say the least.

Overall Quality

There are no lags when using the Horizon 7.8AT, as it possesses Rapid Sync ™ technology in a powerful motor ensuring smooth operations time and time again. This motor also carries a lifetime warranty so you know that it will not wear out quickly! A wider 22” x 60” allows consumers room to comfortably exercise and reach their stride as they ascend to heights of a 15% gradient while journeying towards better levels of fitness health.
The console on the 7.8AT is a wee bit large but has a wonderful color contrast screen which yields tantalizing workout data in easy-to-read formats. Bluetooth capabilities allow for sharing this workout data to fitness apps along with the ability to stream fitness classes or for entertainment purposes while exercising. There are QuickDial™ controls on the handlebars for smoother changes during training as well as quick touch buttons on the console to kickstart workouts into high gear!
