Are you clenching your stomach muscles right now?

Over the last few weeks I’ve realized that any time I ask myself this question, I am indeed clenching my stomach muscles. I relax them when I think of it, but as soon as I’m not consciously focused on relaxing them, they clench up again.

I’m curious how abnormal this is. So, are you clenching your stomach muscles right now? You might not even notice that you are, because it feels normal, so consciously try to relax them. Can you?
