(HealthDay News) --
High intensity interval training (HIIT) is a popular and effective form of exercise. But before you step up your routine, make sure you're doing it safely.
Here are suggestions from the American Council on Exercise:
- Pick an aerobic exercise, and start with a five-minute warm-up. Then for the next 10 to 12 minutes, alternate between higher and lower intensity. End with a five-minute cool-down.
- Start out with just three- to four-speed intervals, and gradually increase to eight-to-10. Engage in a HIIT workout once or twice per week.
- Don't make your recovery intervals (those of lower intensity) too short. Give your body time to rest.
