We find you the best (and fastest) HIIT workouts to build muscle and slash fat

Unless you’re someone who loves running on a treadmill for hours or willingly enters marathons for fun, you might have a hard time finding workouts that push your cardiovascular fitness—and don't take all day to complete. Thankfully, that doesn't mean you have to grind out hours of steady state work to get your fat-burning sweat on.
