it could not be good for your back...if you immediately go work out after you wake up...as your discs are full of fluid...and take some time to shrink back down. i'd much rather have some fuel in me.

And when you seek forgiveness
You will see there is no god
And for all eternity
You will cry my name
so my internet works again ;)
as the guys already said, it´s better to have at least one good meal before working out. but if you´re unable to achive that, have a shake of 2cups of coffe, 5-10g bcaa, 30g whey before your workout.
