<< you should NOT eat before a workout. all the energy in your body gets used in the stomach, leaving less for your muscles when you're lifiting. you want to eat a while before for that reason, so your body has time to process it and you won't lack the energy required to lift. this is the reason behind not going swimming right after a meal, your body basically goes "oh crap, first he's eating and needs energy down there, now he wants it in his arms, huh, wtf" and you cramp up. >>
???????????????????????????Energy????????????????????????????
No. All the blood goes to your stomach to aid digestion, which creates a lack of oxygen.
