It is actually good for everyone to know where they carry their tension. I am a firm believer that the mental contributes to the physical. I am a carry of tension in the lower back and stomach muscles, so twisting my torso from side to side whilein a chair actually works for me. I don't how people can figure this out other than checking into their body (which no hardly anyone does) or to talk to a message or physical therapist of some sort.
