To call boxing an endurance sport is erroneous, a endurance events are characterised by being consistent and low in their intensity and long duration, predominantly aerobic. Boxing, especially as you move up the weights is extremely anaerobic in nature.

Partly depending on style, you're not a marathon runner, you're a sprinter who needs to be able to sprint repeatedly and then make up the oxygen debt inbetween rounds.

I'd suggest researching sarcoplasmic hypertrophy versus myofibular hypertrophy to better understand why gaining 'muscle' can hurt some fighters, but not others.

Boxing has a way to go in terms of strength and conditioning, guys like Bruno trained more like bodybuilders, hence the phobia the sport still has.

Whether Joshua has put on 20lb usefully or not remains to be seen, but the fact remains 20lb on him is not suspicious alone.
We will all just have to take your word for it
