What exactly is interval training? As the name implies, it is an exercise that changes at different intervals in order to mix low, medium, and high intensity workouts on a session. Some may wonder why this would be a recommended means of performing cardiovascular exercises, would it not be best just to pick one and stick with it? The reason interval training is so helpful is because it not only allows you to boost your endurance, but also allows you to cut calories big time. And both and goals people want from their exercise sessions.
You would pretty much walk for 30 seconds, jog for another 30, and sprint for 30 seconds more.
Why is this? Well, some people could never jog or sprint for 20 minutes straight. By mixing up the workout within the same session, you can include jogging and sprinting with walking in such a way that you can get some of the higher intensity level workouts into your 20 minute session.
Also, here is a very important point about high intensity workouts. When you are sprinting, your heart rate increases significantly. When this occurs, the number of calories you burn will increase significantly. When you switch to jogging and walking, your heart rate will lower but because you are shortly returning to jogging and sprinting, the heart rate will not drop down to what it would regularly be when walking.
You will now be in a situations where your calories will be burning at a high rate through the process. Now do you see how effective interval training is? For many people, the ability to jump from one level of intensity to another all during te same session can open the doors into getting in the best shape of your life.
Obviously, the walk, jog, run method is only one example. You can perform interval training with pretty much any kind of aerobics exercise you wish. The great flexibility makes it possible to be creative with interval training while also losing weight and getting into shape.
Just be sure to warm up and cool down prior to starting the interval training session. So, if you want to perform 20 minutes of interval training, a five minute warm up at the beginning and five minute cool down at the end is highly advisable. That means the overall workout will be 30 minutes. Or, more accurately, it will be a highly effective 30 minutes.
