1) Is there any advantage/disadvantage to combining chest with triceps and back with biceps? As of now, I do chest, back, legs, and arms all on separate days. I know some people who swear by chest/tri and back/bi. The reason I do them on separate days is because by the time I'm done with my big lifts--chest/back (bench and deadlift), I'm pretty much spent and can't imagine doing much else. 2) Is there any advantage to being taller or shorter when lifting? I've heard some people say there is and some people say there isn't. Whenever I see people with shorter arms than me lifting, I think that they have it easier than me (not that it matters though) because they travel a shorter distance with their arms (btw, I'm 6'3" and have long arms). I think the same thing whenever I see someone shorter than me squatting/pulling. It seems like they don't really travel that much, whereas it feels like I travel twice as far. Either way, I don't care and it's not going to change anything, but I'm curious.
