Physical strength is one of the most underrated attributes in boxing

He was obviously being helped by someone on the left side of the bar plus the spotter grabbed it from him and he didn't go down all the way. That's why everyone is laughing their asses off lol

 

Physical strength plays a really big part in fighting, also on the psychological side. If you fight a guy and feel that he is strong as a bull you are getting intimidated.
Wlad and especially vitali were famous for being physically strong. You could see it in the clinches. Fury and joshua are also physically very strong as also whyte.
Wlad was very impressed of Joshua's strength. Fury is a very big man with farmer boy strength. Joshua vs fury will be a burner fight.

Strong physical fighters:
Fury, joshua, whyte, pulev
Gassiev
Beterbiev, ward
GGG, canelo
Spence
Garcia
Tank
Inoue

 

Look at how Holyfield manhandled Tyson in their two fights, and he was the lighter man.
