its been proven over and over that the optimal size and weight for a HW male fighting is between 240-265lbs.
Outside a rare few freaks, who are the exception and not the rule, like Lesner and Ubereem, the competition actually gets WEAKER the bigger the guys get.
I know that shertards get enamored by zee muscles but whether its muscles or a build like this...
...these giant guys lose mobility, flexibility, balance, reflexes, stamina ,etc or all of the above.
Again some shertard enamored with zee muscles in the OP will claim its different but history has shown us it is not.
