In a perfect world, we'd all have a good hour of free time every day, specifically for working out.Unfortunately, that's not the case, between making time for work, friends, and family, it's hard enough to just find time to take a breath, let alone crush a workout. That is, until high-intensity interval training (HIIT) gained popularity. For the uninitiated, HIIT workouts are a quick, efficient way to sneak in exercise, but the benefits go way beyond simply fitting it into your schedule. ~ Berceste
