Things to Remember for Muscle Building

I'll probably be updating this list if I think of new things or if anyone suggests anything to me. I've just been watching YouTube videos of people who have done Body Beast and reading up about body building in general, and I just want to start a little list of stuff I don't do well now so that way I can address these issues while I am trying to bulk up.

1.  Drinks lots of water!  I think to not drink all that much water, maybe only three cups or so a day on average unless I am doing a lot of cardio or I am going to work out in the evening. I heard that muscles are made up of like 75% water or so, so if you're not properly hydrated your muscles suffer.
2. Eat all the friggin' time! Remember to follow my nutrition plan and get the proper amount of carbs, proteins, and healthy fats. Make my meals in bulk in advance (I currently make my lunch all in one shot every Sunday), get a carton of egg whites to quickly make a breakfast sandwich in the morning, keep my blender ready to make a smoothie to go with my eggs, and prepackage healthy snacks to take to school and leave in the car, like nuts, carrots, and fruit.
3. Continue yoga poses! I want to maintain or exceed my current levels of flexibility. I hear Body Beast doesn't have much stretching in it, so I am going to have to make a committment to include my own yoga routines. This past month on ChaLean Extreme I haven't been doing so well at adding in my own yoga on the weekends like I had been in the earlier phases. My arms have been so exhausted from all of the lifting, that I am always so tired and my muscles are so fatigued by the time I put in a yoga DVD or attempt my own practice. I am going to have to allow myself a few hours to recover before attempting to do any yoga during Body Beast.
4. Check length of workout! I hear there's at least one workout in Body Beast that is a full hour long. I am going to have to check out all the times and write them down, because on the full hour long days, I am going to have to wake up at 4:30 AM instead of 4:50 AM. I also hear there is one that is really short, only around 25 minutes or so, and on that day I could sleep in a little more, maybe wake up at 5:10? Oh... that sounds so beautiful!
