What do you think burns more body fat?

The reason I ask is because I could never figure that out myself. I did a lot of long distance cycling(still do). I did HIIT on spin bikes. I did running. I used to do more long distance swimming and now do more sprint workouts but still couldn't answer which method is more effective in fat burning. I always read about which method is supposed to be more effective but can't tell from my own experience. I guess what some of you said is right: no matter how you train; if you're gassed out at the end of the workout it will be equally effective. The more time you are able to spend exercising, and in motion, and with your heart rate up, the more calories your body will burn. Also, the more intense the exercise the more calories it burns. So it's a combination - whichever exercise your body can sustan for a prolonged period of time. For example, running vs. walking: traveling three miles, whether you are running it, or walking it, will use up very close to the same amount of calories. If you ran it really fast, your heart rate will go up for a little while afterwards, and you will get some residual calorie burning. However, if you go at little less then sprint speed, in the upper end of aerobic heart rate, this may enable you to run or jog, 6 or even 12 miles, in the same time it may take to walk it., and since you are not sprinting it, you don't end up spent as fast. The overall effect is, you burned a lot more calories. Also, sprint exercises tend to use up the qickly available energy, which is in your blood and muscle. Typically, more prolonged exercise at little less then peak intensity gives your body time to go through the lengthier process of converting some of it's fast reserves into energy. Bottom line is, you want to go as hard as you can for as long as you can. it's a graph with intersecting curves - you go too fast, you may have to stop too soon, you go too slow, you don't cover as much ground. HIIT principle in general usually allows people to maximize the intensity vs. time spent training. But when you take a close enough look, and really want to fine tune the last 10% or so of maxing out the fat burning efficiency, it's best to keep track of how your body responds individually. At that level, your personal lean mass vs. fat reseves, general muscle mass and overall cardiovascular conditioning can come into play, and overall body weight can come into play. This is all asuming that you're not ingesting new calories, especially quick energy type stuff, while working out. Body will always go for the easily accessible energy first.
