How To: Do interval cardio training

In this tutorial, we learn how to do interval cardio training. Start off on the treadmill going at a pace that is easy for you. Increase the intensity of the treadmill every two minutes. After two more minutes go back to normal. Continue doing this raising your intensity each time you start a new two minutes. You can increase it by doing a higher speed, higher incline, or anything else. When you feel like you can't do anymore, log what speed or intensity you were at. Continue to do this exercise everyday, then you will be able to build up strength to do more on the treadmill each day.
