Christ dude I'm not asking for a magic bullet. "Overcoming" is a broad term and trust me I'm not that much of an amateur. Ric knows his shit and in the past mentioned how he started out with very poor arm genetics, plus some of the pics I saw of him in his teens his arms look a lot like mine do. Considering how far he took his physique, why wouldn't I pick his mind over arm training?
Sometimes I wonder if something is lost in translation when we converse. The tone/inflection of many of my posts seems lost on you.
Well, maybe you should formulate your questions more precisely
You just wrote "I'm not asking for a magic bullet", well bingo, there isn't one. His physical development is like any physical development; genetics, hard work, nutrition, drugs and the right mindset.
