Sometimes I get a really nasty cramp/spasm in an abs muscle just below my rib cage. I don’t mean in the digestive system, I mean the muscles that you use for crunches. Which is why I’m having trouble Googling this. It is very painful. I can alleviate it by straightening out and direct massage but it takes a couple of minutes to get relief and the muscle is tight for hours after.
I work out regularly and do four sets of crunches a couple of times a week, rotating to one of three machines each session. I never get it when I’m exercising, just if I’m bending over or something.
Any way to prevent this? I find it difficult to stretch those muscles, but it might help if I could an effective technique to do so.
