I have always had cameras but never recorded any record attempts done in the gym. Like Keith said, we didn't need proof. I don't even have a movie of my posing routines. Digital cameras make it much easier to take photos and not waste money on film. Still, I don't see too many people taking photos of guys lifting unless it is a contest. Those of us who didn't enter powerlifting contests just did our lifts in the gym with one or two guys spotting.
The funny thing about the internet is there is no way to prove or falsify any statement. Even if someone supported what we said or did others could claim they were gimmicks, etc.
Keith once beat John Breznk in arm wrestling. Now, that is some feat. John is the best arm wrestler of all time. Most guys on Getbig with 14 and 15 inch arms dream of benching 250 or maybe 300 pounds. I mean, would they believe anyone has actually done over 500?!
