The workout program is based on Lee Labrada's program here.
The program has you go to the gym everyday. Every third day you just do 25 minutes of High Intensity Cardio. This made my metabolism crazy fast. Professional athletes like swimmers can have over 8000 calories per day, but they burn it and stay fit from working out hard. The carbohydrates, instead of adding to your fat, gets turned into energy. You keep fueling the metabolism fire and you'll be losing weight in no time.
After I lost the near 50 pounds, I had to take a break from working out due to a knee surgery. My metabolism was still a machine months after (even when I wasn't eating the healthiest stuff). After the three months, it'll be easier to maintain it without having to follow a super strict diet or workout program.
