I've heard it said to do cardio in the AM on an empty stomach. Sh*t i am so not a morning person and hate pushing myself after I first get up, but I guess I have to go ahead and grow a pair. http://forums.steroid.com/images/smi.../aaGreen22.gif
It doesnt have to be an empty stomach. clean protien is good. your body will not use it for enegry.
