HIIT is a training method that involves alternating short bursts of strong or explosive anaerobic activity with short rest intervals until the anaerobic energy release mechanism is nearly exhausted. Exercises are performed in rapid bursts at maximum or near maximal effort, followed by intervals of rest or low activity. Because the body substantially recruits anaerobic energy systems, it differs from aerobic activity in terms of intensity, interval duration, and number of bouts (not complete exclusion of aerobics). HIIT’s crucial features of strenuous activity, length of time, and short rest time materially differentiate it from being considered a form of cardiovascular activity. Although there are various forms of HIIT-style workouts that may include exercises associated with both cardiovascular activity and resistance training, HIIT’s vital features of intense exercise, length of time, and short rest periods materially differentiate it from being considered a type of cardiovascular activity. Though there is no common HIIT session time, an HIIT workout often lasts less than 30 minutes in total because it employs anaerobic energy systems, which are best suited to short, rapid bursts. The timings vary depending on the participant’s current level of fitness. Traditional HIIT was supposed to be no more than 20 seconds on and no more than 10 seconds off; however, exercise intensity intervals tend to span from 20 to 45 seconds, with no more than 75 seconds before the aerobic system kicks in. Better athletic capacity and condition, as well as increased glucose metabolism, are all benefits of HIIT training. HIIT may not be as successful in treating hyperlipidemia and obesity, or increasing muscle and bone mass, as lengthier workouts. High Intensity Interval Training allows people who get more in a harder workout in a shorter time. With short bursts of intense physical activity, separated by breaks of relatively slower activity, HIIT has been proven to improve cardiac function and facilitate faster weight loss. If you want to get in shape, you should try incorporating HIIT into your routine workouts.
