This is a great video that reviews an advance stretch of the piriformis muscle.
This is a basic Piriformis Stretch that I usually use in the office. It is well demonstrated however, it should be noted that unless you are very flexable already, it really works alot better when done with a partner.
This is a well done demonstration of a basic hip flexor stretch. Sometimes this hurts the knee that is on the floor so try doing this on a mat or something soft under the knee like a kneeling pad that is commonly sold in the garden section of stores.
