It's just math man, it doesn't matter how much your run, lift or sweat. If you're taking in more calories than you burn you're going to gain weight, if you're taking in less you're going to lose it.

Cardio is good for the heart though, so if we are talking healthy vs. skinny you should be getting in a couple of work outs

Oh, yeah I just meant that you could eat relatively “unhealthy” if you run that much because you’d have to be gluttonous daily to exceed that kind of calorie burn. 

But then again if you tan that much you probably wouldn’t be eating 5-6000 calories a day anyway
