The popularity of high intensity interval training is on the rise. High intensity interval training sessions are commonly called HIIT workouts. This type of training involves repeated bouts of high intensity effort followed by varied recovery times.
The intense work periods may range from 5 seconds to 8 minutes long, and are performed at 80% to 95% of a person’s estimated maximal heart rate, the maximum number of times your heart will beat in a minute without overexerting yourself. The recovery periods may last equally as long as the work periods and are usually performed at 40% to 50% of a person’s estimated maximal heart rate.
Why is HIIT Training so Popular? HIIT training can easily be modified for people of all fitness levels and special conditions, such as overweight and diabetes.

HIIT workouts provide similar fitness benefits as continuous endurance workouts, but in shorter periods of time.
