I posted this same question on VF, but am doing it here to get more responses. I am planning on starting the Body for Life program after Labor Day and am thinking of doing the Crosstraining series 6 days a week. Do you think that should be enough? The book talks about doing only 3 days of cardio for 20 minutes and 3 days of weight work for 45 minutes, so this will incorporate both. Also, any of you 40 and over crowd tried BFL and have had success with it? I noticed that in the book, there is not much talk of 40 and over females who have done the program. What do you think?
