Look at this guy. He's a professional boxer. Why are his trainers and conditioning guys allowing him to get like this?
I like how you're making it sound like its Klitschko's fault. Also, when was the last time you saw Fury gas?
Fury is in between fights. That is what most fighters look like when they are not in training camp actually
He let's himself go inbetween fights... Not a good habit... Certainly not a good thing to do, and it could catch up to him later in his career.
That's what separates the creame of the crop from guys like Fury... Wlad is one his way to becoming statistically the most dominate HW champion of all time, a big part of that is his work ethic. Talent alone can only take you so far.
