Note that I have small and weak abs, thus poor posture. I'm aware of Alexander Technique (Ballet), Pilates, and Yoga. I try to stand and sit tall, but I usually forget. How can I train my body to have "straight" posture? Do you think stretching out my abs through ab exercises will get rid of the red line on my stomach? Is the reason why I have a red line across my stomach is because my abs are too weak to support my body?
