Had an interesting conversation with a newbie to the fitness world today, who is trying to add some build to his frame.
He makes a noble effort. But an interesting topic came under discussion: He told me that a bodybuilder who is at the gym told him that Running on the treadmill reduces muscle gains.
Being a certified professional(ACE), I disputed his claim. I asked him to be more specific, which he could'nt.
In my contest bulk and cut experiences, I have never found running to either reduce or increase muscle mass, rather than a great cardio exercise. Of Course, everyone is different and everyone has their own theories. But I have never once read a published article stating the above by anyone.
So my question is: DOES running decrease muscle mass? I am not speaking of a long-distance marathoner, rather from a bodybuilding perspective. Thanks. ( I could be wrong, who knows?)
