Biggest biceps

It is claimed that Greg Valentino has the world's biggest biceps and biggest arms at over 28 inches! (70cm!)

I disagree, Greg Valentino's arms are not just muscle, he has used huge amounts of sytnhol oil and his arms just look like great big water balloons.

So who has the biggest biceps in the world?

I feel it is Manfred Hoeberl who had 26" arms which at one point was a world record. This is footage from the 1993 World's Strongest Man competition.
