I've heard a lot of people say running alone won't give you the same cardio that you need for a fight. Bas Rutten has said that "one time" a marathon runner came to train with them and he gassed pretty quickly after doing just a few matt exercises. My question is that do you guys believe that there is actually that much of a advantage one over the other. I ask this because I have had runners come into the gym and brand new they are already outlasting us. Their bodies naturally don't tapp anything anarobic and even though they may not go as quickly they always outlast. I think there are a lot of reasons Bas' one marathon runner person could have gassed. One could have been lack of physical strength to perform the specific matt exercises. I have noticed even people with crazy fast workouts always seem to fade if things don't go their way, I include sprints in here. A person like Matt Hughes who does slow runs from 30-45 minutes every mon, wed, and fri never seems to gass out. I think running gives you more overall awareness of your body. As in you know when to relax so not to overexert yourself. Sean Sherk with all his crazy techniques, you can see in the Nick Diaz fight he emptied the tank. Diaz's body however because of his heavy, heavy focus on running never had his body even enter the anarobic level. Long post, but I am very interested in Seano's opinion specifically.
