Sprint 8 — Behind the Science

Why does it work?

Muscle mass naturally decreases and body fat increases as part of the aging process. You can slow down, stop, or even reverse that trend when you use the Sprint 8® 20-minute HIIT workout. When you train with Sprint 8 regularly, you will not only transform your body, but studies have shown the Sprint 8 program can lead to lower blood pressure, lower "bad" cholesterol, and lower body fat.

Scientifically Proven to Release HGH

Sprint 8 is proven to release more human growth hormone into the body — but how does that make it the best exercise for weight loss? Growth hormone does many important things in the body, including regulating body composition, muscle and bone growth, and sugar and fat metabolism. But this human growth hormone isn't produced forever. Gradual and progressive decrease in growth hormone occurs naturally with increasing age during adult life.

There are two realistic wats to reverse this process: injecting growth hormone into the body (this can be expensive and the side effects are unknown), or naturally by stimulating growth with high-intensity cardio exercises like sprint intervals. After three 20-minute HIIT workouts for 8 weeks, research study participants had significantly changed their body composition by reducing body fat and lowering "bad" LDL cholesterol.

A Winning Combination

If you have 20 minutes, you can perform a Sprint 8 workout and spark the change in your body you want to see — improving your health, fighting aging, and trimming fat.

8 Weeks

It is possible to accomplish incredible results with just 8 weeks of high-intensity cardio exercises. The Sprint 8 program delivers better results in less time with fewer workouts than you would expect.

HGH Stimulation

While a basic HIIT workout offers many benefits, including a higher caloric burn, it is the natural stimulation of human growth hormone (HGH) that is more significant. Elevated levels of HGH are associated with increased lean muscle mass, decreased body fat, and higher energy.
