Skibunny,
I think it just depends on what you wish to accomplish.
If your desire is to protect your body fat while building endurance, then I imagine cardio followed by weights could accomplish this goal.
But if you would prefer to do LESS work and burn MORE fat while building more muscle (which will raise metbolic rate), then you would do your heavy lifting FIRST, followed by about 20 minutes of moderate cardio.
I don't know what benefit there is in keeping the heart rate up for 30-45 minutes, unless you are doing it before lifting.
If you don't do weights first, your first 15-20 minutes of cardio doesn't burn much fat - that's where you're burning off what exists of your blood sugar. Under these circumstances, if you wanted to get into fat-burning, then yes, you would have to keep going beyond that 20 minutes to accomplish any significant fat burning.
However, if instead you take advantage of your available blood sugar to lift weights (which doesn't work very well WITHOUT blood sugar anyway), then once you finish, you immediately start burning fat once you do cardio since you've used up all your blood sugar. Since you don't have to waste the first 20 minutes of cardio burning off blood sugar, you really only need about 20 minutes to get the same fat-burning as you would if you had done 40 minutes of cardio BEFORE doing your lifting.
I would argue that the 20 minutes post-lifting could actually burn MORE fat than 40 minutes pre-lifting since you can lift so much heavier if you do your weights first.
But again, if your desire is to train longer, preserving energy and burning less fat, then by all means, do your cardio first. Your goals may be more endurance-centred than body-composition-centred.
Me, I'm just lazy. I don't want to work any harder than I absolutely HAVE to to achieve the end result.
