Are you looking for an excellent way to maximize your cardiovascular workout in a limited amount of time? Then you may want to try High-Intensity Interval Training (HIIT).
A HIIT session consists of a warm-up period of exercise, followed by six to ten repetitions of high intensity exercise, separated by medium intensity exercise, and ending with a period of cooldown exercise. The high intensity exercise should be done at near maximum intensity. The medium exercise should be about 50 percent intensity. The number of repetitions and length of each depends on the specific exercise. The goal is to do at least six cycles, and to have the entire HIIT session last at least 15 minutes and not more than 20 minutes. These short, intense workouts provide improved athletic conditioning and are extremely beneficial in improving fat burning during and after exercise.
The HIIT approach to cardio exercise is very physically demanding and is not for everyone. If you have any cardiovascular problems or other health concerns that limit your ability to exercise at very intense levels, or if you are relatively new to aerobic exercise or not already in good shape, HIIT is not for you – at least for now. If you have any doubts or concerns about whether it might be safe for you, check with a fitness specialist before giving HIIT a try.
