7 reasons to try interval training

High-intensity interval training (HIIT) alternates intense bursts of activity with time to recover. HIIT can be a smart way to squeeze in fitness.

1. It's time efficient. You can get the same or better results in less time if you're willing to push your limits.
2. It's fun. In one study, new exercisers preferred HIIT to steady-paced cardio and said they'd stick with it.
3. It's not just for the superfit. People with diabetes, heart disease and heart failure can benefit. (Check with your doctor first.)
4. It can be good for your heart. In fact, HIIT may be more effective than slow and steady exercise for improving blood flow.
5. Even a little extra effort helps. Intervals don't always have to be maximum effort to offer fitness and health benefits.
6. It only takes 2 weeks to see gains. Researchers found measurable improvements in fitness and metabolism after just 6 workouts.
7. It complements endurance training. Try HIIT and moderate cardio every other day for full benefits.
