No way.. especially some one with bad cardio. Most people cant run past over weight people cant run passed 5mins.
My brother is a freak of nature... he's a lifetime alcoholic, and has a HUGE beer gut. He's at least 50 pounds overweight. And he has cardio like crazy. He's been sponsored on some of the pro cycling teams around here, he's that good. If he *doesn't* do at least 20 or 30 miles a day, he doesn't feel right.
Looking at him on a bike is pretty funny. Big, heavy-gutted dude with a red face and a swollen nose from the lifetime of heavy boozing... putting people to shame on long uphills.
Some people just have big, huge hearts and big arteries. Some people just have smaller hearts, or smaller arteries. I know a person who did 40 minutes per day of cardio for years, but never got anywhere significant. It turns out that her aortic root (where your aorta attaches to your heart) is only about half the size that it would normally be.
Then you get someone like Randy Couture... that at 185 pounds weigh-in (probably 200 fighting) can keep it coming the entire time.
