What Is High-Intensity Interval Training?
High-intensity interval training (HIIT) involves brief bursts of intense exercise alternated with low-intensity recovery periods. It is probably the most time-efficient method to exercise.
The duration of this method of workout is between 10 to 30 minutes. No matter how short the workout is, it could provide health benefits much the same as double moderate-intensity.
High-Intensity Interval Training includes sprinting, biking, jump rope or other body weight exercises.
As an example, an HIIT workout using a stationary exercise bike may include 30 seconds of cycling as fast as possible on a high resistance, followed by a few minutes of slow, easy cycling with low resistance. This could be viewed as one “round” or “repetition” of HIIT, and you would most likely complete 4 to 6 repetitions in a single workout.
The certain length of time you exercise and recovery will vary depending on the exercise you want and how intensely you are exercising.
No matter how it is implemented, high-intensity intervals need to include short periods of powerful exercise that make your heart rate accelerate.
High-intensity interval training provides the benefits of longer-duration exercise in a far shorter period of time. But it could also contribute some unique health benefits.
