No.
The surfeit of "training vids" out there = schmoe city! There are only so many ways to train a muscle and if you've been in the gym for more than a couple months you already know how to do it. Watching your favorite BB training on a video is not going to improve
your physique or inspire you to new heights.
Anyone who buys these videos is certainly getting something out of them, but it's probably not what you think it is. Of course, there is nothing wrong with that.
