I absolutely hate cardio, but I've incorporated in into my workout to help shed some pounds anyway. The treadmill I have access to has a fat burning program that I normally use. Anyway, I upped it to 5.0 in the middle of the program to get a heavy jog going and after 3 minutes of it I was about ready to die. It's mostly based on the fact that I have allergies with something in my apartment (I take allegra to balance it out) but my lung capacity is pretty much crap from that. I realize cardio and lung capacity go hand in hand, but are there cardio activities that won't rely on breathing heavy?
