Arnold just had a joy for bodybuilding and knew how to put it
in it's proper perspective in the balance of life.
Mentzer didn't seem to enjoy the whole process of challenging himself to exceed his previous best
physique regardless of the judges outcome.
Even Joe Weider said that although he had built an empire through extreme dedication and hard work;
he never had the pleasure and enjoyment that Arnold exhibited while reaching his goals.
Arnold - 2:50 - 3:17 "Most people are too close to what they are doing that they can't see themselves anymore."
I always step back and just laugh at myself because you can't take the whole thing seriously.
I believe there's certain things we have to do to keep us going and motivated; pick little goals, go after them and things like that".
Arnold - 3:38 - 3:56 "You have to be able to step back out of yourself and look at what you are doing;
and laugh about it. Because it's all funny, being the best built man in the world "Very Funny".
I think Mentzer did challenge himself and always strived to improve. Indeed, one of the basic tenets in this training philosophy was progression. That to get bigger you have to get stronger and to get stronger you had to be bigger. So you always strived for the addition rep. Always strived to increase the resistance.
You may be too young to remember but I was already in my late teens/early twenties when Mentzer was all the rage. Before that I spent my teen years reading the muscle books like everyone else interested in bodybuilding. There was no internet so the mags were all we had. There was always talk about the Weider principles. The pump, peak contraction, the flushing principle, certain exercises for width, definition, peak, size.... but never really much talk about progression and getting stronger by adding more reps and more repetitions and training intensity.
Mentzer I think seems to have taken things too seriously. He didn't have fun in the way Arnold did. Arnold of course was ruthless and would stop at nothing to win. But he also seem to have fun, enjoy bodybuilding and enjoy life. Mike was more of a loner and intellectual. He struggled with a lot of the great issues of life and battled personal demons. Arnold, in comparison, might be though of as a bit more shallow. Didn't become too preoccupied with the bigger more transcendent issues about "what does it all mean?" Just have blast. Surround himself with friends that I believed he truly liked to be with.
Remember that final scene in Pumping Iron during the ride back with "Big Louie"? Like me, most of us were probably teenagers when we first saw this movie. You can't help but like Arnold and want to be like him. You know that in one situation he'd stick a knife in Louie's back if he had to, but in another, beginning at around 1:35, you see him just having fun and really enjoying life.
Mentzer was far more influential to me than Arnold was in a bodybuilding sense. But Arnold was Arnold. Living life to the fullest. Who could ever imagine that someone from such an obscure subculture could rise to the level he did?
