The previous post has a lot of interesting opinions, and quite a few misconceptions...
1st off, disregard the H2O statements that were made considering adipocytes. They could really care less about your state of hydration. Their response is solely to glucagon and insulin released into the bloodstream. In agreement with bbfit, it is crucial to maintain a good level of hydration. The list of things that it affects in the body could go on for pages. If you're really into cardio, then you may also have heard of over hydration (yes, it is possible, look into it if it's on your mind)
I do disagree with bbfits proposal on a biochemical basis. Those cardio workouts can really pay off. Aerobic workouts have always put forth a necessary 20 or 30 minute training period to start tapping into your fat stores. It's true. Your muscle houses about 600 grams of glycogen, an energy source that is much easier to use than breaking down your triglycerides. It's only afer your muscle has completely obliterated this source that it turns primarily to adipocytes for compensation. Meanwhile, your body has been secreting glucagon in response to an energy deprivation state. Adipocytes break off fats to send to the liver for metabolism. Triglycerides shrink over time as you use their stores, which equals fat loss. For us weightlifters, it's important to replace our protein stores along the way, which are also used to a minor extent in the process.
Of course diet has severe impacts on this process. If you keep building those adipocytes as fast as you break them down, don't expect to see a thing. Usually, if you're motivated enough to stick to a constant aerobic schedule, you'll be motivated to watch your intake as well. (I hope)
That 20 to 30 minute period won't last forever though, so don't look at it as a major roadblock to fat loss. As your body adapts to your cario schedule, it'll tap into adipocytes earlier and earlier. Eventually, it all begins as soon as your workout does. (Lance Armstrong releases fats as soon as he steps onto his bike, no joke)

Cardio is very simple.
If you want to share the great benifits of it, just go do it.

Well, in defense of BB1fit's cardio post, it was never intended to say cardio was in any way bad. The whole purpose of that if you read it is to enlighten those who do ONLY cardio that they will probably not meet their goal of a lean hard body. You must incorporate proper diet and resistance training. Now true, Lance Armstrong is a phemominal athlete, I marvel at what he does. But, I wonder how he looks with his shirt off? If you want to be thin, maybe cardio is ok. If you want that sculpted tone body...well, look around you in the gym at the ones you know who thrive on long bouts of cardio and don't do any resistance training. Need I say more?

I think its essential to realize that we all come from different experiences. bb1fit is obviously a proven trainer. Not to say hes right 100% of the time, but he does knwo what hes talking about.
On the other hand, there is evidence to support so many viewpoints on weightlifting, fat loss, etc etc etc. Its just a matter of finding out what works for YOUR body.
