Working out on an empty stomach
I go the gym immediately after school since it is only like 2 minutes away (i live 20minutes away, so obviously i dont want to waste gas and drive back and forth). The thing is after school im normally starving, like it's making all kinds of sounds. I dont have any pre-workout supplements (not that i know of), but i take Mass Tech by Muscle Tech for bulking. Any ideas on what i should eat before a workout, that is easy to take out of my backpack during my last class? I cant just bring a blender to school..
Basically:
-what are some easy to take preworkout snacks?
-is it bad that i workout on an empty stomach?
