Re: Crossfit (or any other workout) in the early AM
Note - I am a USAW Sports Performance Coach and CrossFit L1 Trainer that runs a box at home and has a good background in nutrition.
Personally, I am in the eat before you train category. At least 30minutes to an hour before hand. It is going to take whatever you eat that long to hit your bloodstream.
If you don't have the time for sweet potato hash browns with eggs for breakfast, opt for a protein shake and piece of soft fruit. It is kinda important to get some sugars in your system. Especially if you're doing 20min+ metcons.
If you don't fuel before you go, your body will end up catabolizing muscle tissue to get glucose to feed your brain. This is even more true if you are in the aforementioned WOD till you drop category.
This is my personal Pre-WO shake (30-45 minutes before):
One scoop Isoflexx Natural
Half a banana
Some frozen blueberries or strawberries
raw milk till desired consistency is reached
It gives me 50g+ of protein, simple sugars and quality fats. I stack this with my pre-WO supps: (fish oil, magnesium, alpha-lipoic acid, and plain old creatine monohydrate that is dissolved in black coffee).
Adding your BCAA's to this will give you a pretty amazing pre-WO meal replacement. Remember to "chew" your shake. Mimicing that chewing action stimulates the salivary glands and enzymatic processes. It will help aid in digestion.
Your post-WO meal should be cooked beforehand and can be done the night before. This will help you be able to eat immediately after while your body is starving for fuel.

and beef.
The plate that is at the 4:00 mark. This is generally what I eat 90 minutes pre-WO.
