I was wondering if anyone had a concise way of explaining why cardio exercise mobilizes our stored fat to be used as energy? I've been told it takes 20 mins. for the fat to be broken down and passed into the bloodstream, is this accurate?
Secondly, it's well known that too much cardio can rob you of muscle mass. Again, can someone explain what happens to make this occur? Thanks all!
