Due to the constraints of my schedule I do my cardio about 1hour after lifting. I finish my workout the get in a quick protein shake, with no carbs I don't feel like puking all over the cycling studio, then go do my cardio. Though when I have time I do go in the morning but I also throw in a small protein shake, again with no carbs, before the session to ensure some protein uptake. By small I mean about half a normal shake.
