Preworkout Food/Drinks?

What do you guys recommend one should eat or drink prior to hitting the gym. Especially someone who is on a low carb diet and needs that energy prior to the workout very badly!

Please recommened stuff I can find around the house or in the fridge :), I know about Biotest’s great products, just don’t have the money to try them…:frowning:

Coffee about an hour or so ahead of training, works great for me.
