P90X advice?

Hi MFPers!

I'm starting P90X this afternoon and am really looking forward to it - but I'm wondering if anyone out there who has done the program has any advice for me? I'm only doing the exercise portion, not the eating plan since it's pretty meat-centric. I eat pretty well in general (vegetarian, and I make most of my own food from scratch) though I will be making an effort to cut my sugar intake in half, since sugar is my weakness.

I'm 5'6" tall, I haven't weighed myself in a while but I'm guessing I'm somewhere around 145-150lbs; I've got good base strength, but I want to gain lean muscle and get down somewhere into the 120's.

My only safety/injury concern is my knees - no past injuries or anything, they just get sore when I do high-impact stuff and if I'm not careful I end up in a brace for a day or two.

That said, anyone have any advice? Thanks!! ^_^
