Can Leg Work Double as Cardio?

Ive read many times about the heart rate getting up in leg work and was wondeing if it "can" double as low impact cardio as well?

I do not have a monitor, but my leg routines are typically 75-90 minutes long. I usually have to rest longer than Cathe's typical rest periods due to being out of breath, but I don't have the patience to wait a whole minute or more usually.. so should I count that as a cardio segment as well perhaps?

So on that note, is there a difference between using heavier weights right from the start, and pre-exhausting the muscle first and then using moderate weights?

For example Im looking to gain a few pounds of mass in my legs, but I've found the hard way that I really can't lift a 60lb barbell over my head and back down again, in between sets, throughout the duration of a workout..

Would pre-exhausting first, and then using a lighter weight (say, 50 lbs) for a couple more reps have the same effect or would I have to find another way to utilize the heavier weights for less reps? (hmm.. might be a good question for Cathe :)
