"also u said ur a marathon runner? being that its VERY likely that u would loose almost all ur muscle mass, since marathon running burns muscle mass, its the reaosn why u dont see bulky marathon runners" -ranging1
To comment on ranging1 post... I have done a lot of research on this topic. Some of what he says is kind of true, but mostly not. Distance running burns glycogen stores 1st... then fat... then, and rarely so... muscle.
It does take an extrodinary amount of calories to fuel the body for very long distances, so the right high calorie diet in essential, for muscle development and high aerobic exercise.
This being said, it is still rather difficult to be "MR. World" and run marathons, for your body will try to compensate with leaner longer muscles, rather than the "popping out" bulk variety. That is why I've scaled down to more of the 5K races.
I thank people like ranging1 and everyone for their comments and experiences, for it is good fuel for thought..
