newbie with posture questions

Body: 

Just got my book and video last night but am trying to get into posture right away.

1. Are there any muscles that you often feel it in to indicate that you are in the correct posture.... I'm wondering if I'm doing it correctly....

2. I work behind a computer all day... I have one of those fancy ergonomic chairs that you can adjust every which way and has a lumbar support pillow that can be inflated and deflated to your preference. Is there a particular way I can adjust my chair to help encourage sitting in posture?

I'm 9 months postpartum with cystocele, urethracele (sp?) and rectal prolapse..... my mother has a completely messed up pelvis and rectum from botched surgeries and I don't want that for my future.

sorry for any misspellings (learning a new vocab.)

1. initially I felt the posture the most in the muscles of my upper back, between the shoulder blades.

2. for sitting, I sit at the edge of my chair, I don't care how fancy the chair is or how adjustable, I find it easiest to scoot to the edge of a plain old hard chair so my feet are firmly planted where I want them and my pelvis is rocked forward. I find that as soon as my thighs are resting on the seat its harder for me to keep my pelvis forward. this may be an individual thing, so play with it.

Gmom, same experience here. I have a kneeling chair, but I set that aside, it is easier to use the edge of our regular chairs (b/c I can sit wherever I want), no pillow. Pelvis rocked forward.

I hardly use chairs with a back at all because they are usually wrong. I sit on the edge of chairs that have the seat sloping backwards, and I have an adjustable height stool for my computer. I use a lumbar cushion for easy chairs and have a small one in the car that I travel with, whether by bus, train, car or plane. I figure that God gave me muscles for a reason, so I use them.

i try as well to sit perched forward. at work if i sit too far back eek, i'm reclining before i know it. i should see if i can take the back off...
i also get up and walk around a lot, just because when i work at home the kids require it and at the office i end up needing to there anyway, but definately keeps my body happier.
