Kownacki is nearly always a fat ****. He is consistently around 260lbs and was for the 4 fights before Hellenius. I think that performance was down to him not being mentally focused and taking Hellenius seriously. He wasnt fatter than usual.
Why people like him always like that ? Not training enough and don't try to be the best shape possible. Just because there is no weight limit does not mean that you should be fat and lazy
