>>76273360i mean myfibrillar vs sarcoplasmic muscle idk if theres anything else to be looked into desu but its strength vs size aka density/size. thats why bikers have such huge calves and legs, because low rest sets are basically a cardio workout and give little strength compared to denser muscle youll feel it in the pump if you nail a heavy set vs just spamming reps.
roiders cant train strength as well because theyre constantly about to tear something but they can get way more massive cardio muscles. and no if i cut its just so i can do another fast food and beer bulk for longer.
