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. Available exclusively on Studio Series Treadmills by Horizon Fitness.

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.
