I found this on Building-Muscle-Guide.com (http://www.building-muscle-guide.com/pre-workout-meal.html)
The other part of effective pre workout nutrition is eating the right types of carbohydrates. Low glycemic carbohydrates are what you need as they provide a steady stream of energy to the body.
High glycemic carbohydrates are what you need to avoid before an intense workout. They are rapidly released in your bloodstream and your body will release a surge of insulin to try and level out your blood sugar levels. This results in a quick rise of energy, then followed by a quick fall. This will leave you tired and weak, which is the last thing you want to happen during an intense workout.
So avoid high glycemic carbs and make sure to eat low glycemic carbs for your pre workout meal. Some good choices are apples, oatmeal, low fat yoghurt, low fat milk and wheat bread. These low glycemic carbohydrates will give you a solid stream of energy.
