So normally when I go for a run or to the gym, I am tired in a bad way in 15-20 minutes. But I've noticed that on days where I go for burger and fries from a food truck, I can do exercice 4 hours later for 40-50 minutes before feeling exhausted, and even then I feel tired in a good way. Obviously eating burger and fries every other day is not really a good long term solution, so does anybody have good recommendations about what (and when) to eat to get through a workout with a maximum of energy?
I imagine that the basic idea is "carbs", but then what kind? how much? how long before exercising? etc.
