Tyson Fury's Confidence and Bravado

Tyson Fury's confidence and like just the bravado of like is really interesting. Like one I have a hard time with he's such a bad body. It's almost like I wonder if like the excess body fat or maybe the lack of muscle or everything helps him be more flexible and takes more blows maybe. But it's just hard for me to imagine that if you're training at such a high level like I don't understand where all the excess bodyfat comes from.
