I've always understood that you train first for whatever your goal is. So a marathoner would lift (if they lifted at all) after their run, but someone building muscle would lift first. I can't imagine doing anything after HIIT (or even doing my HIIT after lifting on this program!).

I agree with Luv2Lift's answer - HIIT is a great compliment to lifting if you are hoping to burn fat - it keeps the metabolism stoked and burning, moves the muscles and helps reduce ongoing soreness after lifting (not lactic acid - that is gone within an hour of lifting). But HIIT or cardio of any kind depletes glycogen and your ability to really put your muscles through a maxed-out workout. If your goal is to build muscle, then I wouldn't suggest more than a warm-up (like Lou discusses in the book) before lifting.

I'd love to hear other's thoughts on this too!
