Whenever Frank Zane's name comes up I think of too many funny encounters. I have friends who were students in his high school math classes through the '60s and '70s. If you live in the Venice, California area MOST people who grew up in the area had at least one class with "Mr. Zane." He's famous in Venice for having been a really cool high school teacher that all the kids (and parents) really respected, but almost nobody knew he was a pro bodybuilder, much less a 3 time Mr. Olympia.
I'm a little lost as to the comments being attributed to Frank Zane and not deadlifting. Frank Zane deadlifted his entire pro career, and he still deadlifts to this day. He credits the deadlift for building his dynamic lower back and giving him a great core strength.
