Thanks for the help. If I am understanding BCAAs correctly, you take it instead of protein? How often and are there any potential side effects?
As far as routine...I have been doing a three day split: chest/tris, back/bis, legs/shoulders. I've been stagnating around the same weight, I need to change it up. Full body routines are pretty intriguing...basically you work everything in a session, three times a week? This is probably borderline overtraining, no?
How does something like this work as a diet:
7:30-3 eggs, english muffin, banana, protein shake (or BCAA?)
10:30-PB+J or PB+honey sandwich, an orange or banana, granola bar or power bar
1-grilled chicken sub, orange, banana
4-PB+J or PB+honey, banana (I'm not very creative...), power bar
Gym around 6:30, protein shake before it and after
Dinner around 8-whatever my mom makes

Usually healthy, meaty
Casein protein shake before bed around 11
Does it seem like I'm lacking anything? Any advice on a good multivitamin? I'm 21 by the way.
Again, thanks for any help, I'm really glad I found this site!
