No need for a huge paragraph so here's my question: I'm not skinny, and I'm not fat- I'm lean. I'm a mesomorph, which means that I have the potential to be very physically fit if I were to actually try to work for it. What are the most core exercises you would suggest to someone like me who has the potential to be very muscular, isn't fat, isn't skinny, eats what he's supposed to eat, and has access to a college gym with almost any exercise machine you can think of?
