Ill address a few points.
1) I think the "monotonous and boring" is because what we do is "deliberate practice".
2)Broz learned under Krastev, and while he is on a different version of what we do, its still effective and he definitely knows what hes doing.
3) As Koing said, everyone at the academy works full time and/or goes to school. Theres only one person there currently who has none of those obligations yet theres another who has a family, but its just a matter of organizing your life to accommodate the lifting. Yes its hard, yes you have to sacrifice things, but you can make it work if you really want it.
4) Nekohlay was here during Abadjiev's first attempt at coaching in the US but Nekohlay eventually went back to Bulgaria.
