I used to be able to do L-Sits easily. But after stopping all forms of workout for a while I tried to do an L-Sit again recently. When I did it somewhere in my lower abdomen (between my pelvic region and lowest ab) I heard and felt a pop. There was no pain but it felt like something happened in that area. I then did it again after a few weeks and the same thing happened.
What does this mean? Do I have to work my way up to doing the L-Sit? Or is there something wrong with my lower abdomen?
