This content is protected From this camera angle his arms look bigger. Also, his elbows are at more of an angle when hes flexing which affects it a little bit, if you flex your biceps at a 90 degree angle they'll seem noticeably smaller than if you flex at a 50 degree angle or so.
i just watched and compared when you watch in real time yea there is a moment were his arms look bigger maybe that photo was just snapped when his muscle was more relaxed. This content is protected
He’s posing on a slightly different angle in both pics and again the lighting in the 1st pic is better. The shadows under the arm create the illusion of more muscle roundness.
Its obvious that those pictures were shot from 2 different angles, but it does appear to me that he did lose a bit of muscle mass for this fight. Maybe, it has to do with rapid weight loss?
It's not the angle difference, you can see Fury barely has any muscle separation in his arms in the most recent weigh-in.
