Technically I don't workout at NIGHT, however to me it is......
-I work overnights (10pm-7am), and the only time I can set aside to legitimatelly focus on working-out is immediately after work/before bed. I wake-up around 7pm and go to sleep around 11am, 5dys/wk. I've been doing this for quite a few years now and have had no problems with diet/training.
-My meal schedule looks like this (Bulking Phase):
Meal 1 - 7:30pm
Meal 2 - 10:30pm
Meal 3 - 1:30am
Meal 4 - 4:00am
Meal 5 - 6:30am (Protein bar/Pre-workout)
Workout - 7:30am
P-W Shake - 8:30am (50gPro/80gCarb/10gCreatine/1gALA
Meal 6 - 9:30am
Meal 7 - 11:00am (Whey/Casein/Egg/P.B. Shake)
SLEEP - 11:30am
Now my Cutting Phase is another story, meals, timing, carbs, fats, etc.... But, as far as Post-Workout carbs, I usually get a little concerned so I simply drop the 80g of carbs P-W down to 50g, and Meal 6 & 7 NO carbs and NO Peanut Butter! (damn I luv PB! lol)
