Looking for a tough workout that you can easily knock out in nap time? HIIT — high intensity interval training — is ideal. The fitness routine punches way above its weight when it comes to fat-burning and muscle-strengthening. Designed to get your heart rate up to 85-95 percent of its max effort for 15 to 20-minute spurts, HIIT is what you need when you want results but don’t have an hour a day to devote to the gym.
