Well, I do agree with you....but the theory behind it is "aerobic" vs. "anaerobic" exercise. Weight lifting is said to be the latter.
Aerobic exercise being a state of increased cardiovascular activity, that is sustained for at least 15 - 20 minutes or longer. Using a large muscle group, rhythmically, while maintaining 60-80% of your maximum heart rate
Scotty , I think gym based cardio sucks in general.
Console yourself with the fact that by increasing your lean muscle mass and regularly stimulating thosee muscles with weight training you are burning fat!
What doesn't kill us

If you go to musclemedia.com you can read an article by Shawn Phillips on HIIT (High Intensity Interval Training). Scotty I think you're right to an extent. Appearantly, they've found that periods of going from high to low heart rate does help burn fat.
