Well, I've been training people for probably close to 20 years and have been in the game longer than that. My methods are somewhat controversial. As far back as the 80's even some of my workout buddies laughed at some of my methods but they stopped when they saw some of the people that started winning shows.
For example, so many people think that cardio is a must to get ripped. This is not always so. I do have people use it, but most of the time it is because mentally they feel the need. Personally I think that it is a waste of freaking energy that time could be well spent recovering from a hard workout. Also, people tend to get way too fat in the offseason. They also don't realize that they are burning plenty of calories by working out, assuming that they are not standing around wasting time between sets. Most people wait too long between sets anyway. If you just busted your ass working out for 45 min why in the hell do some feel the need to walk into oblivion on the treamill for another 30-60 min and run your body further into the ground? Like I said, I do use it sometimes, but in reality it is not needed to get ripped.
