The second week consisted of 90/120's. It was ninety seconds of running followed by two minutes of walking (at a brisk pace). You do this for twenty minutes (of course that's after a five minute warmup of brisk walking). By the time I did my last ninety seconds of running, I felt like the last set went by too fast. I pushed myself harder and faster and I felt TERRIFIC after doing so, but felt like I could run even longer. This is a good sign. My body is sore right now because of it, but it's worth it in the end.
After I came home, I did crunches for about a minute, literally. It was straight crunches for that time. I feel really good. I'm feeling healthier, better, happier and best of all skinnier...although it doesn't show yet, it's under there somewhere. Well keep your spirits up. I'm starting week three tomorrow.
