Fasted Training, Neck Training, and Protein

I answer questions on the following topics - BCAA before fasted morning training ala Martin Berkhan. - Some people say the best way to build traps are with HEAVY barbell shrugs. Light alternatives? - Thoughts on concurrent periodization? - AJA's approach to neck training - If you have a large post-workout meal, what are the effects of low-fat vs. moderate fat. Like a big thing of potatoes with lean chicken vs. A meal with beef, eggs, cheese and carbs - calories being equal - Any problems with having casein or any other slow-digesting proteins without concern for timing?
