only thing ive seen on charles glass is when flex wheeler pussy trained and had charles glass carry weights for him and put it on the various machines or when he got creative with gunter have him training using different angles and make a lot of drop sets...
but surely, there must be more than that.
it would be interesting to hear what he got to say about rep ranges, whether he believes there's a point going over 15-20 reps on excerises, whether he believes going to failure is necessary, and if so, how often... maybe if he can point out some exercises most doesnt do, but should be doing... which exercises he believes are the pontentially most dangerous... etc stuff like that, all from a average trainer perspective, not a pro.
