worked out my biceps 2 days ago and both of my valves cramped up, this never happened before, occasionally one calve but not both. yesterday was leg workout, did okay with calves but never felt them burn out like that before. well, tomorrow is my chest day so we'll see if my chest will cramp up, I’ve been on the revised diet for few days now, hopefully this will help. if not, could I be lacking on potassium perhaps?
