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.
