Yeah, I know that copying what a 10 year bodybuilder is doing is no good and not the fault of bodybuilding as a sport. But I'm making an even bolder statement: that using concentration exercises like bicep curls, leg curls and (especially) 3-4 different angles of shoulder and chest work, espcially with machines and high reps, will very much increase your chances of injury. I'm telling you that whenever I walk into a commercial gym or my building gym (i.e. not a powerlifting or oly gym) I see easily 90% of the people doing stuff I know is in bad form at worst, and at best will give them the most mild of training regimens. I blame the culture of bodybuilding (in the U.S. at least. I read that in Eastern Europe there is a very different attitude and training culture starting from school). I argue that barbell training -- functional training more broadly, which includes calisthenics if you want -- is vastly safer and superior to bodybuilding and indeed yes, it does require a bit of personal training and instruction in the beginning.
