Rapid Sync Motor Perfect For Interval Training


Power your workouts with a 3.5 Continuous-Duty Horsepower motor and 500 lb thrust incline motor. Together, they create the most responsive drive system available in a treadmill. That means faster changes and a smoother, more efficient run.

The Johnson Digital Drive System featuring Rapid Sync™ Technology ensures no lags or delays between speed and incline changes. It responds 33% faster than other treadmill motors, so you’ll never fall out of step with a fast-paced interval running class.

Maximum Results Minimum Time


Achieve maximum results in less time with our 20-minute high-intensity interval training workout, proven to burn up to 27% body fat in just eight weeks.

Sprint 8 is more efficient than a basic HIIT workout because it engages fast-twitch muscle fibers and naturally stimulates Human Growth Hormone (HGH). This triggers a response in the body that melts fat, encourages lean muscle mass and increases energy.

Extra Large Deck Gives You Room to Run


Whether you’re a sprinter or a jogger, this 22" x 60" deck provides all the space and comfort you need to run at your pace. All Horizon treadmill decks are built with shock-absorbing 3-Zone Variable Response Cushioning to give you the ideal amount of flex and support in all phases of your stride.
