With such intense exercise sessions, I wouldn't want a lot of my body's resources devoted to digestion during exercise, so if you're going to eat real food for exercise fuel, I would finish eating at least 4 hours before exercise. Make sure that you have filled up your glycogen stores within 12 hours of anaerobically demanding exercise, e.g., the weight training. How soon after your workout you go to bed should determine the amount you eat after a workout; you don't want to be digesting a huge meal, but it's fine to refill your glycogen stores with a bit of complex carbs, e.g., chili w/ beans, sweet potatoes w/ butter + a protein.

Also, I recommend a 10g of a BCAA powder within 60 minutes on both sides of an intense workout. It lets you work hard and helps prevent muscle soreness (DOMS) after. I forgot it one day, and the extreme soreness ensured that I won't again.

Stay away from "frankenfoods," such as commercial bars of any kind. They aren't food.
