Its 90 minutes a day, 6 days a week of intense workouts, cardio, stretching, pull ups, push ups, weight training, you name it.
I've spoken to a couple of people who have done it and they love it. Well, they hated it, because it kicked their asses, but they loved the results.
My illnesses over the last 6-8 months have prevented me from doing my usual routine, and in the process, I've gained 30 pounds since October because of it. I'm 6'3" 255 lbs, which is great if you're a linebacker in the NFL, but I'm nowhere close to being that fit.
I have to do something, and all the non-biased reviews of the product from different blogs and websites seem to love it. They all say that you have to stick with it, and it will beat you up in the process, but if you follow the rules, the results are amazing.
