All I am saying is if building muscle and body composition is your goal than running is counter productive to that goal. Remember running is the antithesis to building muscle and unfortunately there is no getting around that unless you change the type of running you are doing ie sprinting instead of steady state cardio. There are many article and studies showing the negative affects associated with steady state cardio. The other issue is running is actually not ideal for cardio. MMA athletes have known this for years and that's why they choose many other alternatives that are much more efficient without the negative sides of steady state cardio.
I know many a runner and I have always supported there running because of what they get out of it at an emotional level however I do try to convince them to do some resistance training so it offsets the issues associated with running. But again they are runners and their goals are much different. If you are a bodybuilder or interested in building muscle efficiently I would choose the more effective efficient methods.
