>>76382387 (OP)i think genetics matter a lot, but childhood athletic development and nutrition also makes a huge difference.
i have one friend who 'should' have good genetics. his father was absolutely stacked and his mother was decently fit as well. he was malnourished as a child and never did any sports or anything other than play video games. as a result, hes a skelly who seems unable to put on much muscle at all despite constant efforts. he could certainly do better training and dietwise but his gains compared to mine or my other friends are significant.
likewise, i have a friend who has been athletic and well fed his whole life. decent genetics especially for his arms. guy puts on muscle like nothing, his only issue is staying lean cause hes a big dude who loves to eat.
>>76382481i really like your point here, i think i share the same stance. like when i see a program or special exercise routines for "building boulder shoulders", when the actual routine doesn't matter. just stimulate the muscle and your insertions and genetics will decide what you look like. the only thing we decide is how hard we stimulate our muscles and our diet.
