Do you have a job where you sit at a desk for 8 hours a day?  Most people don't know that their body was not designed to sit for long periods of time.  

When the body is in a position for 49 minutes or less, it takes 20 minutes of movement therapy (yoga, bodywork, exercise, etc.) to release that pattern.  If it is in a static position for 50 minutes or more, it takes three to four hours of opposite action or movement therapy to release that pattern.
