Well ALC, dont know if you heard but, there is more to bodybuilding then the mister olympia contesters, and there is more to strengthsports then the "open weight cathegory and strongman, wich i didnt include".
Most bodybuilders wich are amateurs, or not that juiced up and weighing 120kg at 1m74, will run surprisingly well considering their weight, cause trained for hypertrophy.
In strenghtsports, you compare the "open class", wich is a fraction of the sport. Go ahead and look at the -120, -105, -93, -85, -75, -63 classes. u'll find shredded athletes who never do cardio. And i can assure you they run just fine
Klokov, an olympic lifter said it the best once. He was asked if he did cardio. He replied "yes sometimes i squat over 10 reps"
