High intensity interval training aka HIIT , is a cardio workout that focuses on short bursts of intense movement. A typical HIIT session would consist of 1 minute of high intensity exercise such as a sprint followed directly by a minute of rest or low activity (repeated). HIIT sessions are short and take usually between 5 to 30 minutes. HIIT sessions are not recommended for beginners as they are very taxing on the body’s muscular and respiratory systems.
