I'm a cross country runner at heart so I love running 80 miles a week (or more) AND I'm trying to bulk up a bit since I'm very lean (obviously). I've read that you can't really have both unless you are a real genetic anomaly. I eat a LOT of calories and lift, but I can't gain muscle mass.
Is there a limit to how much I can run and build up more muscle mass? The reason I can't just stop running is because I love it so stopping would suck and you lose it pretty quickly too.
