Some stats:
He's actually around 6'3" LEGIT. He weighed 290 pounds in his college football days. He weighed 270-275 in the mid to late 90's in the WWF. He cut down to about 260 pounds when got his first movie role. Then he kept losing weight and went down to about 220-225 pounds. He had HUGE legs at one point. Those are gone and so is the rest of him, with exception to his arms, which actually have improved over the years.
