just a quick question...

After I do my planned weightlifting workout (I'm following the "New Rules" plan), I jump rope, doing intervals for 15 minutes.  I should know the answer to this by now, but sometimes I get all jumbled up because of the plethora of information I read: because my HR stays so high throughout (even when I've stopped jumping for 30 or 45 seconds it only falls from about 180 or 185 to, say, 165), is this burning fat as efficiently as if I were to, say, rest for longer, let the HR get lower, and then jump again?  Since I do it after weights, I've already depleted some of my glycogen stores, but I do want to be maximizing my fat loss efforts right now, and didn't know if another exercise, say a lower-intensity session on the elliptical would be more effective.  I enjoy jumping rope and am trying to start building up straight jumping time again, so I'd likely do a combination if something else was recommended as well.

Just need someone to reorient me here.

 That's the interesting question, isn't it? You probably won't be burning as much fat as you would at a lower intensity - while you're working out. The higher anaerobic intensity workouts use mostly carbs for fuel.

 However, paying too much attention to what happens during the workout and ignoring what happens post-workout is the basic mistake that all the cardio junkies here and elsewhere keep making; it's the post-workout adaptive response that's the reason anaerobic interval training leads to 9 times greater fat loss for half the energy cost of steady state cardio.

 So yes, you'd probably burn more fat while working out if you went with less intense intervals. But you're going to lose more fat overall with the intense interval trainng you're doing.

That was what I was missing : post-workout.  Forgot that that was the point (I think it is, anyway).  Thank you!
