Depends. Are they actual natural HWs? Obesity is the single biggest killer of Testosterone. Fury on the low T program.
Another Bomber joins the ranks alongside @Brighton bomber and @Brixton Bomber Welcome @BoxingBomber Bomber Squad! And yes the king of HW is usually the king of boxing.
Fury has been gifted a body made for fighting by the gods of war. To denigrate his body blubber (bodyarmour) as obesity is absurd.
Fury is 33 years old. You can get away with adipose tissue around the abdominals when you're under 35. As you age all that puts tremendous pressure on your organs and will lead to high blood pressure, cholesterol, possible diabetes, heart attack, stroke, cancer and erectile dysfunction...
