i want to start doing cardio before school...i start school at 7am, so was woundering how early i should wake up if im ganna be doing 40 min of cardio....i also need to eat before, right? and what should i eat that will get into me really fast and not effect the fat burning process, and how long should i wait before my i can do cardio from my meal...also could somebody give me an example of a post cardio meal as well....i was thinking along the lines of cup of oats and whey protein with fat free milk but any help would be appreciated.
