Of course, bodybuilders don't refer to it as 'training for running and cycling'. Its just that running and cycling is what they spend all their time doing. Apparently all that running and riding "burns fat". And there are various theories about how to avoid looking like a runner or cycler despite training exactly like one.
Personally, I just can't fathom the stupidity of this. Runners look like runners. Cyclists look like cyclists. Train like a runner or cycler and you'll become a runner or cycler; and you'll probably look like one. Not even drugs can change that! Hell, we all know the Tour De France cyclists are drugged to the eyeballs with all the same stuff pro-bodybuilders use. Ever wondered why not a single one of them looks like a pro-bodybuilder? Just MAYBE it has something to do with the fact that they TRAIN AS CYCLISTS!!! Is anybody really surprised by this?
Now I know that bodybuilders have never been famous for their intellect; they've worked hard for their reputation as galactically stupid. But how the hell did hardcore bodybuilding get so deeply infested by the most worthless, mediocre, mainstream, training methods straight out of "the Biggest Loser"?
Why in hell would anybody think that endurance training has any relevance to a bodybuilder? Is it because when its called 'cardio' and done on a stationary machine in a gym it becomes a different thing? What? Like: "A rose by any other name is completely different to a rose"? Stupid is as stupid does. And endurance training by someone trying to impart the look of limitless strength is STUPID!!!
The facts remain: walking is not exercise; its not burning any quantity of energy or fat worthy of mention; its not helping or even bothering the heart of a hard-training athlete; its just a complete waste of time. Can anybody REALLY believe that a person will wind up looking MORE like a cartoon superhero because they engaged in WALKING??? How??? WHY??? Forget all the contradictory science; stop studying the trees, look up and see the forest: walking doesn't help create a muscular physique!
Running on the other hand is endurance training; its training to become a runner and will make you LOOK like a runner. Again, why would anybody think otherwise? Surely even the most cliched 'dumb-bodybuilder' knows that!?
