Dial it Up Quick Precision Control


Experience faster, smoother transitions between intervals using QuickDial™ controls that simplify speed and incline adjustments without breaking your stride. On the right, roll the dial forward to increase speed and roll it back to decrease speed. On the left, roll it forward to go up the hill and roll it back to come back down.

Rapid Sync Motor Perfect For Interval Training


Power your workouts with a 4.0 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.

Light Up Your Workout Data


Push your interval workouts further using the 60 second countdown timer while viewing all of your key metrics on dual full color LCD and LED displays.

Bring your personal devices to your workout without blocking your data, thanks to multiple convenient media holder options and a built-in charging port.

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.
