I only watched a few seconds. It's the usual "no else knows anything, modern bodybuilding is crap and toxic." It's true that experience is absolutely a wonderful resource. I'm humble but I think I could help newbies, and even veterans, get much better results, get on the right path (in my humble opinion, it's just that, an opinion) faster, and I'm not talking about chemicals, even though there I also could help someone avoid mistakes. I don't offer unsolicited or even solicited advice much. But one thing with these old-timers that irritates me is how they almost always feel they
sculpted their physique to their liking, when the truth is that genes dictate maybe 95% of that. The body develops as it wants to. Even that realization has come from experience, and it has just strengthened more and more over time. It's just a recurring theme with almost all of these

I clicked a Charles Glass clip by mistake the other day. It's just complete crap for the most part. If you have bad biceps they aren't going to start growing by lifting the bar over the head in the preacher curl. I always hone my technique according to how I feel, most aficionados do this, but it's not going to do much in the overall picture.
