I know the best time to do cardio is in the mornign after you wake up. I do it this way too. But i know its supposed to be on a empty stomach so that you are burning fat while yoru glycogen (however you spell it) stores are low. But do you think its ok to have a small protein drink 8oz or so about 20min before you go. I mean i have done both and feel like wheni wake up i need protein!! I have been doing cardio , abs, calves Mon, Wed , Frid, in the mornings and without at least a protein drink i feel slow as hell, and rush to get it done so i can eat.
So what do ya'll think?? Is small amount of protein gonna slow down my fat burning at all??
