Large collection of info for beginners

Overall good info. However, I am curious as to what support Alan Aragon and others have for the statement that you can get similar health benefits from weight training as you can from cardio? I've tried googling this, but all I've found is this claim being made with no scientific support, and it seems to be used more often as a justification used by those who dislike cardio.

Well I can not answer your question directly, but what is being referred to is maintaining basic cardiovascular health, nothing more. If you perform things like squats, deadlifts, bench presses, overhead presses, barbell rows, chin\pullups, dips, power cleans\snatches, etc. at or near max effort (as much weight as you can handle in whatever rep range you work in) you will get plenty of elevated heart rate for keeping it strong. I guess support could easily enough be gotten by wearing an HRM while performing such lifts in said manner. It should not be until someone is more advanced that they would have a true "leg day," but people who do have them sometimes get near or over the line of vomitting, so they are probably getting a pretty good cardio workout.

Edit: I just happened upon a bit of anecdotal evidence http://www.myfitnesspal.com/topics/show/705076-heart-rate-during-weights-vs-cardio
