Interval Training

 
    Interval training is a type of physical exercise that involves bursts of high intense work out followed by low intense periods of time. During these types of exercises it can be said that at one period of this work out you go all out on a certain exercise. After you go all out ton an exercise you continue with the exercise, but you are not supposed to give it all you got, you are supposed to work out at a low intense way. During the low intense work out period your body recovers.
    Interval work outs are part of many types of sports. Sports like running, cycling, and rowing are great examples of sports that are associated with interval training. Most racing type of sports are the ones that usually have to do with interval training. Like in running, the runner usually would sprint as fast as they could and for a very short period catch a breath and recover from the sprint and then continue with the spinting part.  Also in cycling interval work out may be found. As a cyclist would start a race they would cylce at an intense speed. As the race would go through the cyclist would have to continue, but have to continue an a low intense speed in order for the racer to catch his/her breath.
