He lays out a progression that starts at whatever interval allows 25 minutes of work, then gradually stretches the running intervals and shortens the walking ones until continuous running becomes possible. His argument is that staying in the aerobic range for most of the session builds cardiovascular fitness while avoiding the soreness and burnout that end most attempts. Read along with the original article(s) here: https://stevepavlina.com/blog/2005/04/build-fitness-with-mild-interval-training/ Quotes to ponder: "If you haven't exercised in a long time and have gotten out of shape, mild interval training is a good way to rebuild endurance and cardiovascular fitness without killing yourself." "The advantage of this type of interval training is that you're still spending most of the time in your aerobic range, so your circulatory system will get the benefit of that conditioning." "Even if you're terribly out of shape, you can use mild interval training to rebuild your fitness to a healthy level without causing yourself tremendous pain and discomfort."
