Any program can work if you follow it well enough. That is why there are so many different opinions in the fitness industry. Doesn't mean they are the most optimal or the best value.
The beach body products are definitely convenient in that you can do that at home but I know more people that dont make it through the 90 day programs than those that complete it. I definitely dont think it is any more effective than other programs and its probably more expensive. I just picked up two programs from Jason Ferrugia for $10.
All that said if it works for you then keep it up, all that really matters in the end is finding what is best for yourself.
