I know that I have muscles in there, they stop me from folding over and allow me to sit upright, but that seems to be the extent of it.
i went to try out an exercise class a couple of weeks ago that required sit up, and I couldn’t even do 1 . My body seems completely incapable of lifting my upper half off of the floor from a laying on back position.
So how do I improve this, what do I do to strengthen these muscles enough to start being able to do sit ups and then build from there to improve overall core strength?
