Which is the only reason I brought it up. If I thought the OP knew it, I wouldn't have bothered mentioning it. If you go back and look at my initial post in this exchange, it's basically a comment to the effect of, "Hey, you may not know this, but competitive body building and martial arts may not be compatible... and here's why."That's fair. I'd agree with you in all that. I don't know enough about competitive bodybuilding to state if it's that intrinsic so I'll take your word for it. Even with that though, the initial OP stated that OP wants to do bodybuilding but also wants to do martial arts. To me that suggests he/she's not got that foundational knowledge yet. It would be like someone saying they want to do jujitsu, but also want to do (something I can't think of that involves shins), and warning them about shin/footburns. Anyone within the sport already knows that those are things and how to deal with it if needed, but it's a surprise and useful info for those still looking into it.
Okay.Again, not addressing the rest about whether or not average competitive bodybuilders do/don't know that, or any assumptions that have been made that they do/don't. So not addressing this line: "You wouldn't expect someone to say, well, there are some well informed jiu jitiero out there, and some who are less informed."
Since I've got no clue how accurate the comparison is for bodybuilding. Just stating how it relates to the OP as important information for him to know. Beyond that and further arguments I can't really say much.
