For flexibility, sit in seiza, then lean backwards (knees close together) and touch the back of your head on the mat. Relax and try and lower your shoulders down if you can - may take a while at first!
As both a former rehab nurse and an aikidoka who has a blown acl, I must take issue with this commonly used stretch. In the opinions of every orthopedically trained with whom I've consulted, the consensus is this places too great a pressure on the knee joint (specifically the meniscus), and that since there are a variety of psoas and quadriceps stretches that DON'T compromise the knee, there is no reason to continue doing these.
