Is the cardio system susceptible to overtraining ans the muscular system is? i mean i know you can fatigue yourself and lose lots of muscle if you dont keep your body fueled while training intense cardio, but my question is more along the lines of will your heart/lungs/cardio vascular system plateau much like your muscles will from overtraining?
Overtraining your muscles comes from not letting them recover, whether that be from not eating enough, or not getting enough rest, or working that same muscle group too often right? So the only muscle in your cardio system is the heart and does that need days off? I would think not since it never realy gets a day off anyways, and you are not trying to make it bigger like you do your muscles.
So what do you guys think? If im trying to become a cardio mad man, will the results come faster if i train eod, rather the ed? Or can i go balls to the wall twice a day as long as i keep my body nourished and get my z's?
