sports specific doesn't optimize your body, that's what we're talking about here. I have to admit, I hated running when I was young and I mistakenly thought I could get into tip top shape if I trained real hard, and I got into great shape but I learned how limiting the boxing skills are for your wind. People are always trying to look for shortcuts and new, sexy ways to do things, sometimes the wheel cannot be improved. That guy you mentioned who worked with fighters from my old gym, I don't know anything about him but i've seen pics of guys running with weights attached to them, it just seems so unnesseary, it might look romantic and liek the guy is training hard but I don't really believe it's needed that bad. And for whatever reason, most of the guys from my old gym have ended fights heaving and breathing hard after even not so tough fights. I'm not gonna mention names but there was one guy who was starting to make a name for himself there and I told one of my younger buddies who still trained there "his stamina is fucked" not that I knew the guy but I saw how they trained and sure enough, he had a loss that stopped him from getting anywhere because his punches didn't work and he was exhaused after two rounds, i think it was ufc but I can't remember offhand, it may have been another org. DJ seems to have his stamina under wraps but he's about the only one I've seen. Ivan came in shape a few times before his outside issues fucked his career up but believe me, the guys I saw really just hangout. Whether other places are like that or they all are, I don't know but it looks like it from the results I see. Like I said, it's more a social thing for these guys than anything else, which put me off of it. I never understood people who have to fake being friends with people who won't even be in your life in five years. never. but then they thought i was weird, I just wanted to fight, the socializing, the politics, the laziness all literally made me physically sick just thinking how long and slow a road it would be relying on incompetent people. Boxing in my area was and is pretty nonexistent so I would have had to relocate and take a risk with that and I was fully aware how deep the talent pool was in boxing.
