Anatomy trains

I am my own guinea pig for the massage moves. So:

I worked on the quad lamborum and released a couple of tight spots. Just a slight change in that released the entire lower back...

I worked on gastric and then soleus. The particular stretch for the soleus is extermely effective. I held it for a while, enough to let the myofascial release happen. I could feel the muscle just let go... And that changed something in my mid back on the same side of the body! That area also let go... And it took me a whole day to readjust to my "new body". The entire back felt so much looser and longer.

Now let's hit the books to find out what this means :) There are classes in anatomy trains too.
