There is about as much secrets/special methods in training as there is in becoming a genius at math or chess or writing sonatas at five years old, that is to say zero secrets. Train very hard, eat enough good food, get proper rest. Everything else is genetics, after you have been doing this for a certain ammount of time you will plateau and then drugs come in to play.
Just train the way that feels right for you and your body, not someone elses.
I train extremely frequently because that's how i like to train, it works best for me because i recover very quickly. Would i tell everyone to train like that? No...A lot of people get burnout and feel that training less frequently works, great if it works for you then that is your path.
Stop looking for the holy grail and go out and fucking kill yourself training would be my advice to anyone starting out, and if what you are doing isn't working, listen to your body and adjust it until it does work.
