It's nothing truly ground breaking at all. Muscle confusion is a load, it's basically switching out your exercises for a new set of exercises that works the same muscles in a different way. On top of that it's just 'X' hours a day of circuit training.
Circuit training consists of X exercises in Y sets...
Long story short, circuit training gives your metabolism an eight hour after burn if you do it correctly and try really hard.
It's just more diet and exercise wrapped up in a nice clean package trying to sell you stuff you already know.
HOWEVER, if it works for you, you can't really complain with the results. For some, like myself, it's probably just the push I need to expand beyond just jogging and doing kettlebell work outs every other day. Results are results no matter what package it comes in.
Muscle confusion is a widely accepted theory in the weight lifting community. It isn't necessarily called "muscle confusion" or whatever. That name is probably just a marketing gimmick.
Every good workout entails changing your routine every week or every couple of weeks. If you do the same exact things every day, your body will adapt and your results will slow dramatically. Switching routines, mixing rep counts, and doing both unilateral and bilateral exercises are absolutely necessary.
I started doing P90X because I read a number of books on different weight lifting programs and the same basic ideas kept popping up in each book.
Compound exercises, switching routines frequently, super sets, cross training, mixing rep counts...those theories are the landmark of any good exercise routine. These same ideas form the foundation of P90X. It isn't perfect because it honestly can't be as an at-home system that requires very little equipment. It is a solid system, though.
