Do what works for you, but don't forget to give credit where its due - we are talking about the patented "Weider Instinctive Principle"
Seriously, I don't have the video's, but I've noticed bodybuilders saying one thing in Weider publications and another thing in their own book. This includes differences in form, reps, training split, etc. I think a lot of people don't even really want to lift weights, they just do it to "get in shape" and so they want to do it as easily as possible and M&F caters to that.
I enjoy lifting. I like going to the gym, I like the pump, I like moving big weights (well, big for me, I know a lot of you guys move much bigger weights than I ever will). What sucks is that I'm sure training methods are advancing, but I don't feel like I can trust any of the magazines for accurate advice. "Get rock hard abs by next week in 18 seconds a day with out new workout!" Sure. . .
