Stomach Sitting Videos I'm Already Pretty Thin But I'd Really Like Abs By The Start Of The School Year. What Should I Do?

I'm already pretty thin but I'd really like abs by the start of the school year. What should I do? - stomach sitting videos

I am a size zero, but I have no muscle tone in my stomach. Haha, I started Pilates, but not really so much, any advice? I'm in Europe, so I bought a few videos and I know my business and make the oblique abdominal muscles, but also any other advice would be greatly appreciated. Would it be possible to abs for the beginning of the school year to develop? I think I was in the eighth month of September.
