I remember Foreman saying he decided he was looking too much like Foreman from the 70s, so decided to put on the extra weight rather than to cut down to 225/230, which was his original plan.
I thought Foreman was good at 243 to 244 pounds in his fights with "Sekorski & Trane." 235 for Qawi was a bit too light and hard to keep for Foreman, but that 257 for Holyfield in 1991 proved too heavy and Foreman appeared slow... MR.BILL
Cooney also rocked Foreman in round 1 in 1990 for a brief moment..... Foreman was rocked / wobbled during his comeback career.... MR.BILL
The Canadian Lakusta got his attention too. Plus it was made known that for what it was worth (little, in my opinion), Hassan Shabazz decked him in sparring.
Foreman said that between fights in his first career, he would walk around at 250+. I thought Foreman looked good at about 232 pounds for his fights against the Toronto 5 and Dino Denis. And today, Foreman doesn't look that big. Back when he was training hard in his comeback, Foreman looked to be about the same weight that he is now. Maybe he's going vegan like Mike!
