The only issue I have with this type of workout and Im not doubting its validity and effectiveness is that I dont want to become a "machine".
I don't want to have to train a body part 500 times a year, Im happy training it 50 times a year if its growing.
As no one said, you are not going to get 10 times the benefit.
Paula Bircumshaw one of the best bodybuilders ever to come out of the UK (famously flipped all the judges at the Arnold classic the wanker sign to applause from Arnold himself
) used to train for about 4 months a year leading up to a show, the rest of the year she didnt touch a weight apart from aerobic sessions.
Her position was that the body grew and responded better to periods of rest and hard training, not consistently.
You stop getting DOMS the more you train as opposed to training a body part every week to ten days.
As again each to their own but taking it literally if I could look like i do without going to the gym then I wouldn't be there.
For me working out and training is a means to an end.
