I dont even know what you're talking about.. What does runner who run alot have to do with someone who hit the weight room hard and does slow paste cardio for 30 min 3 times a week..
The guys that you mentioned run for 2-4 hours almost everyday, dont eat like a bodybuilder (less than 60g protein and 1500 cal a day) and dont do weight training, ofcourse they'll look like a stick.. And powerlifters tain for power, there are tons of small skinny guys who can lift heavy..
i myself do 20min slow paste cardio on the stationery bike 3 times a week and im getting bigger and stronger day by day, and im 100% natural dont take anything no roids or supplement expect creatine..
CARDIO DOES NOT BURN MUSCLE, ITS A MYTH, DONT CARE IF YOU WANNA BELIEVE ME OR NOT.... THE ONLY WAY YOU ARE GOING TO BURN MUSCLE WITH CARDIO IS IF YOU ARE ALREADY AT LOW BF% (7%), GETTING VERY LITTLE PROTEIN AND CALORIES AND DOING TOO MUCH CARDIO..
SINCE YOU GUYS ARE ALREADY JUCING I DONT THINK YOU NEED TO EVEN WORRY ABOUT LOSING MUSCLE, EVEN ON A CALORIC DEFICIT AND UP TO 2 HOURS OF CARDIO EVERYDAY WONT BURN MUSCLE...
I AM STATING THE FACTS, ITS NOT AN OPINION..
sorry for the caps, it needed to be said..
Actually, as both a D III runner (a long time ago) turned cyclist/triathlete I have to correct you.
1. No one runs 2-4 hours a day except maybe one day a week if training for a marathon (notably certain women with body image disorders will do something like this but they are going slow and have severe physical (and mental) issues)
2. Even in college we may have run 10-12 miles a day but it was at a 7/min mile pace so we were never out longer than 1.5 hours.
3. Even on speed work days, we may do a 5 mile warm followed by some speed work, then a cool down and even then maybe 1.5 hours.
4. As far as food--I would put my college cross country team against any same age body builders for caloric intake--as we need at least an extra 1500 just to stop from wasting away.
5. When you are in caloric deficit (a true deficit)--and I am right this very minute and have been for two months, you burn muscle in the form of amino acids (hence the NO3 smell from your skin). What is a FACT is that it is
physiologically impossible to convert fat to glucose --the glucose the brain requires must come from amino acids--from breaking down muscle tissue--(AND where does the energy come from for this cycle--cleaving off part of a fatty acid molecule). So you do burn fat AND muscle--period--there is NO WAY AROUND IT
You understand some macro concepts but where the rubber hits the road you are in over your head.
6. I not only have first hand knowlege of the above I will start talking about various metabolic cycles if you wish to discuss this on a deeper level.
7. as far a steroids--only certain ones will curb muscle wasting when in severe caloric deficit--curb, not prevent (again, personal and academic experience)
