Sit down somewhere quite. Touch your tongue to the roof of your mouth and take 7 seconds breathing in, hold it for 10 seconds, then exhale for 5 seconds. While doing this if you're a woman put your left hand over your right (if you're a man put your right over the left) on your stomach. More specifically the thick part of your thumb. This is a eastern meditation technique used to build Qi(ch) and relax the muscles.
