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.
Keep up with the studio
For less
Get the flexibility and versatility you demand, for less than other popular treadmills on the market. Instead of investing in an expensive touchscreen, use your own device to stream whatever classes you choose. We'll never require you to pay a subscription fee to use your equipment.
