Looking to shred up while preserving muscle? Then you need to try sprinting. Use this easy-to-follow progression to start losing fat faster.

Sprints are hard. But they’re only hard for a little while, unlike the 30-45-minute steady state runs that are still the hallmark of so many routines. But those who are willing to push their stride to the max for a few brutal minutes are often rewarded with more burned bodyfat, a higher resting metabolism and more muscle preserved. The science is legion (and growing) but here’s a condensed helping of some of the awesomeness that interval-style sprinting has to offer.

>> Increases Power: Research suggests that high-intensity interval sprints can help to increase your body’s mitochondria count. More mitochondria, referred to lovingly as the “powerhouse” of your body’s cells, means more fuel burned and more energy produced by working muscles. This has enormous carryover to pretty much anything involving movement while also making you leaner and more powerful.

>> Increases Fat-Burning: Sprint workouts are, by nature, shorter so they may not burn as many calories as a typical steady-state workout. But a single session of high-intensity training can boost post-workout fat oxidation by 75 percent. Think that can help you on your way to Leanville?
