I guess I am different in my lifting and techniques. I have watched this stuff(P90X) and see that all these fad workouts are based off a few simple characteristics: muscle confusion and DIET! I know in the "Getting in Shape" thread I mentioned most people usually need a life changing event to get them to start doing some physical activity. Some of us do it for our jobs. Bottom line, most can't keep up with the diets that come along with these workout regimens. If I were to stop and start doing P90X, I would be sore and in about 3 weeks, I would see some change and even more a dramatic change if I were on a strict diet. If I were to take an individual and put him through what we do on my team here, it would hurt as well. Again, the muscle isn't worked a certain way for a long period of time, anything you do will make you sore and you will get some result out of prolong exercise. Diet is the foundation for all physical fitness....Hope this helps! {toast}
