Don't underestimate the power these videos can have on your mind. You will have a whole new outlook on training and the bodybuilding profession as a whole.
I personally have seen about 5 that I can remember:
Jay Cutler - New Improved and Beyond (my personal fave)
Ronnie Coleman - The Unbelievable
Dorian Yates - Blood and Guts
and of course both Pumping Iron movies.
All of these were amazing and I literally watched them the first time with my mouth hanging open the whole time.
Even if your goal is not to become the largest mammal on earth, the wealth of visual information available from watching these videos is extremely valuable.
And the most important thing is that it invigorates and motivates you for weeks. Anytime I start feeling stale or depressed about my training I get a new one and it always seems to pull me up.
Would love to see a forum for this as well as Bodybuilding competitions as these too seem to have a similar effect on me.
BTW, anyone else go to the North Carolina State Contest last weekend?
