just trust in the system. i was hesitant as well until you start seeing the results. Trust the program, it works, and you will see the results as you hit your peaks!!
The major fatloss on this program doesnt really come from the workouts, the weightraining workouts help you maintain and increase muscle, the 20 minute high intensity cardio workouts strengthen you heart and make you fitter, the real faloss occurs when you switch your nutrition to how you have been eating to the bodyforlife style of eating, when you do this your nutrients go way up but most importantly your calories go way down, that calorie swing from higher to lower is where the real fatloss occurs, by the way some people lose fat with no cardio on other programs, lastly to make the 3x 20 minute intense cardio sessions on this program work, you really need to dig deep and push yourself for those 20 minutes, they need to be super intense
