Why AJ has a poor gas tank

Joshua's endurace decent now, more of a boxer instead of a Olympic athlete

all bodybuilders have horrible cardio, all that muscle mass requires a lot of oxygen. Joshua looked like Reggie Miller in the amateurs, but hey, his muscles is what makes him popular on Cuck Island.

He's gone 12 rounds no problem and he koed 2wlad late. So I wa snt aware he had stamina issues. I must be naive

Joshua won't come in under 240 pounds, he was weakened and over-trained for Ruiz II. Joshua will come in the low 240's against Tyson Fury. I don't think people should be concerned with Joshua's preparation 'It is Tyson Fury's preparation people need to be concerned with'. I will say one thing? Tyson Fury is the favorite for this fight, and I think he should win. But if he attempts to bring back his old school riddler style, and comes in at 250 + pounds 'He will make this fight extremely difficult for himself'. The Riddler style was a bi-product of Peter Fury's training, I honestly don't think Fury puts himself through that type of training anymore 'And it may back fire if he attempts to become the Riddler again'. Fury implemented is Riddler style last against Deontay Wilder I, and was decked twice 'Once badly'. People on these forums, seem to want to ignore the fact that 'Tyson Fury does not move anymore, and he has been hit in all of his fights frequently since his comeback'. Fury fought the way he did against Wilder because he knew he could muscle and push Wilder around. I don't even think most of his punches even landed that cleanly against Wilder. His clubbing hooks just had enough strength and mass behind them they were moving 50 lb lighter Wilder around. Can't do that against Joshua. I don't think Joshua is all that comfortable coming forward anymore either. Last time he did, Ruiz caught him.

1. AJ is an exclusively fast-twitch athlete: he's a natural sprinter (young Femi broke his school’s year 9 record for the 100M) and is therefore not genetically built for endurance. 2. Being a natural sprinter in build and therefore relatively skinny, AJ (like David Haye to a lesser extent) is not a genuine super-heavyweight: his heart and lungs are small in proportion to the size of his pumped-up bodybuilder physique. His organs have to work overtime to pump enough blood and oxygen to his muscles, which leads to early fatigue and the pressure on his artificial body increases with age. His excessive musculature also rigidifies and slows him down more than the same weight would rigidify and slow down a natural big man with the frame, heart and lungs to carry it and he will especially struggle when he has to carry the weight of a much bigger man as well in the most important fight of his life. 3. AJ's style is highly explosive: it's based on throwing extended combinations of power punches to overwhelm his opponent and this leads to him gassing if he can't take his opponent out there and then. AJ doesn't just take a round off here and there; when he's tired he needs at least three or four rounds to get a second wind and that depends on his opponents being unable or unwilling to punish him while he’s exhausted. 4. AJ isn’t the best at handling pressure (partially due to his concerns over his poor stamina and suspect chin) especially post-Ruiz: excessive nervousness and fear rapidly exhaust your energy supply and cause you to gas out more quickly. When you are gassed your punch power declines, punch frequency declines, speed of punch declines, speed of movement declines, amount of movement declines, reflexes decline, timing worsens, evasiveness declines, accuracy declines, co-ordination declines, agility declines, balance declines, punch resistance declines, strength declines, mental fortitude declines, aggression declines, fight IQ declines and it emboldens the opponent. Energy is everything in a physical sense, so gassing out hugely reduces your effectiveness as a fighter in every respect. Very interesting, Im a big AJ fan but I'm not blind to his poor gas tank. He has clearly bulked up too much from his teenage and early 20's years. He isn't naturally built to be as muscled as he is and his body struggles to get enough and distribute the oxygen around his body. But his weight has been coming down, he does always seem to want to try to learn and try to improve and seems to of realised he was carrying too much muscle mass. ​ He is never going to have the greatest gas tank and he's never going to push and maintain a crazy pace but hopefully he continues to try to improve it the best he can.

Joshua learned a lot from his loss. You make a lot of good points but it’s going to be interesting to see what Joshua does going forward. 247 for Ruiz 1, 237 for the Ruiz rematch. I think he would be wise to try and stay under 240 but he was just over that again against Pulev. For Fury he’s going to need to be light to conserve as much as possible because Fury fights more relaxed and therefore more efficiently than Joshua.

His stamina is not all time great stamina, but? I think people are getting carried away on this thread 'Not that I have read many post just yet, but I can imagine what has been said' Joshua's stamina is good enough to compete with most heavyweights these days 'A trait of most heavyweight fighters these days, is that they really cannot fight at a pace'. I don't even think Tyson Fury has great stamina, although it is marginally better than Joshua's etc

- -Puredeecomedy observing the illiterati boxing butterfly 'perts swarm over a HOF great in his prime. AJ the unified record setting heavy champ minting his own fortune while Fury continues to back down from his first title defense for 6 years and counting. No matter, when he does step up will be the end of him.

Excellent write up If you were AJ how would you improve your stamina? Eat less and Cut muscle if it even a thing? It's a difficult one because too much muscle is just part of the problem. He's naturally very explosive and fast twitch at any weight, he has a very explosive style and he doesn't handle pressure well. If he comes in heavier he's got more punch power, punch resistance, power in the clinch and confidence in his size but if he comes in lighter he has more speed, agility and stamina (provided Fury is at range and not ragdolling/smothering him). I would say he should come in heavy and try to catch Fury cold in the first round because trying to play the long game with Fury is a losing strategy, whereas he has a puncher's chance in the first two or three rounds while his gas tank is ok. AJ isn't a fast, agile, 12 round heavyweight so he shouldn't try to be. The worst thing AJ could do is to come in at 235-240 lbs and box cautiously against a 275 lbs Fury but I suspect this is what he's going to do.

He realised that and slimmed down after losing to Ruiz.

I’ve always thought he looks like a skinny dude wearing a muscle suit. His small head, relatively narrow shoulders and wrists make me think he’s not a naturally ‘big’ dude. Just lanky. If you look at Joe Joyce or Daniel Dubios they look naturally big.
