Less cardio, more muscle

[beenie]

when you do an exorbinant amount of cardio, like it sounds you do, your body uses it's own muscle for fuel, i think its after 20 minutes, any carbs you've eaten are burned, for the next 20 minutes, your body taps into fat, and after that it starts burning muscle along with fat, your body is designed to preserve it's fat stores so you have energy to burn in the long run
the problem with that is that your mucles are the engine that burns the fat, so when you kill the muscle, you kill the engine, over time making it harder and harder to burn fat, that's why marathon runners look like shit and sprinters look jacked

No, no, no. That's what they were saying last year. It was first 20 miinutes was carbs, next 20, fat, and after that muscle - I remember that theory well - but now I think it has been disproven - (I hope my sarcasim shows up in this, because this is my point that the "common wistom seems to change every couple of months). The theory was that you had an internal clock that would aoutmatically swich over at thos interval. If you crossed time zones during your workout I am not sure if you could fool your body clock.

The "Common wisdom" today is that you need togo at least 30 minutes EVERY day, but no more than 45 minutes. So, I am trying it for a couple weeks. I started 2 days ago, but it still seems that more intense longer MUST be better. I would love a scientific explanation for this that I am able to understand.

And that line about, "that's why long distance runner look like cra and sprinters look so goo," really is no longer the case. Sounds good, but there are a lot of long distance runners that are really buit these days. Further, using this theory, tryatheletes would look like shit too, right? Of course they dont cause they now train with weights. Seems to me that the reason they used to look like crap was because they weren't weight training, no that they were doing too much cardio.
