Well, some bits make sense others not so much.
Massive thanks for the reply btw.
I did gymnastics for 12 years intensely, So i know my core and Ab muscle are set like stone, or well enough. Which rules that out. I'm also still pretty flexible, Can bridge right over and still can sit in splits. So it's not flexibility.
However, I'm a web developer, which requires me to sit on my ass 8 hours a day. And it does seem somewhat irritable when sat in certain positions. It's getting a lot better since i stopped Hack squats and Free squats with the bar... That seemed to aggravate it. So i'm about 8% back to strength. Ideas?
