Greg did a signing at a local supplement shop when I was running our university Nutrition, Health & Bodybuilding club. The shop sponsored/supported our club so we had some volunteers and had a chance to meet and hang out for a bit after the event along with one of his sisters.
He had two blocks of ice with fans blowing on him the whole time, and he couldn't make it up more than 3-4 steps without having to take a second or two to collect himself. We were the same height, and I was hovering around 245lbs and fairly lean. He dwarfed me by so much that I have no doubt he was 350lbs+.
He was a very pleasant and friendly person to us, and his sister was wonderful.
Ronnie was 270 at this year's Olympia.
At 400 pounds, that'd make Kovacs a full 50% BIGGER than Ronnie.
I doubt he ever hit 350.
Did Kovacs ever really weigh over 400lbs?
