I have no experience at all with yoga, but I just learned the difference between the inner and outer abs and that when people say "the core" its often mistaken for the outer abs.

I have really bad posture...and have had that for years. I'm 23 now, but back in the 7th grade I had a pretty bad back spasm and also found out that I had scoliosis (my back problems actually go even further than this actually, but I'll skip it). My scoliosis has improved a lot since then, though some more minor things have happened since. But the thing I want to correct the most right now is how much my stomach protrudes. I'm around 5'11 and around 147 pounds, so that's pretty skinny, yet my stomach sticks out a lot. I used be more active and do lots of sit ups, and I never had a flat stomach. I can see that the sit ups kind of worked cause I have abs when I flex them, but then I have a big tummy when I'm neutral. I'm pretty inactive now though...just study, eat, and play video games =/

So, I know life style has an effect on my posture, but are there any good exercises I can do that work my inner abs? I feel like maybe my spine is too compressed for this to be possible. When I'm neutral, I have a "swayback" posture, when I try to stand tall and have good posture, I have that posture where my stomach, though flatter sticks out more and my butt too the other direction. Also, I remember a chiropractor asking me to sit on the ground with my legs extended straight out and to try to lift my upper body up to form a "L" looking form. I can't do that, as hard as I try, my back is just rounded...
