idk where to put this so i jus figured here. anyway i was doing situps at home in front of the mirror today and on the negative my left uppermost abdominal muscle felt like it cramped so i shot up and it was still cramped.
i looked at it closely and every other ab muscle was relaxed except that one, it was still contracted almost under my ribcage! after a few painful seconds i watched it slowly slide back into place which was like a scary movie so what gives? wtf was that?
