You mistake the Einstein thing, and then fixated on it. Ego. I'm not saying I know more than he does. I know I don't have the same amount of experience and such. Never said I did. As well with your sister. What I did say is CC is outstanding (and that I think he's wrong - and that he is totally wrong about the body-weight exercises vs CC thing), as well as MT not being what your sister made it out to be. I did forget to mention that there isn't a standard with MT. After reading the original book, I went online and looked up stuff about it. I found all kinds of groups and stuff using the name, but using altered methodologies - like if they were packaging it for a particular audience.
Which brings me to the the marketing thing: people find an audience and then find the best way to market it to them. This is because people are fickle. It doesn't necessarily at all measure the effectiveness of the product, just that they were able to get people to buy it. And, no, Furey didn't say the exericse wasn't that good, but that the layout of that page wasn't good. That's the way your bro said it, anyway. Although, I have to mention, he writes much more impressively in an article where he might have a lot more time to think about the content and proof read it an all.
Back on CC and training: actually, there are ways to increase resistance without using weights. (I'll tell ya if you wanna know.) And speed is often not a decent (I know he didn't say it was the only) criterion to base a training regimen on - but it would be for his audience. I still say these are the best all-around exercises, but regardless notice he doesn't use just a couple-few, let alone one. He uses several. And, he's right, CC isn't a program. We're not talking about programs, here. DUH.
And, no, that Mahler doesn't do conditioning anymore say anything, necessarily. That he doesn't lift anymore, and for years say anything? Not necessarily, cos he could just be obsessed with kettlebells. He still links the CC article. He wouldn't if he thought of them even closely to what your bro does. No, the reason Mahler does mostly kettlebells (not only, cos he does do lighter, in-between conditioning, as well as mentions it in his newsletter workouts and stuff) is cos he thinks they're the most effective tool for his purposes. They're the only gear of that kind I recommend. But his level of training is so far above most people that it isn't even funny. He trains smart, but he trains intensely.
Bottom line: I know what I do works. It'll work for anybody, with less work than anything else, and at least as comprehensively as anything else. All my own experience and those I've trained confirm this. If I find something better, I'll - as your bro says - use that instead. I'm not saying it doesn't exist, but I haven't found it. I haven't seen it in the little I've seen of his. But he and I are different: he has a goal, or goals, in mind. I have aspirations to be a certain way. He is gain-oriented. I'm process-oriented.
