Sinking and turning in push hands

I am experimenting with sinking and small turns internally in this video . Alex, my partner, pushes towards me and I receive his force, roll him off, and sink under him internally. You may notice right after the rollback, he pops out of his kua and then a wave goes up his spine and his neck straightens. I then follow his reactions and apply the same method as before until his structure disintegrates. After a period of basics training we go into the lab work part of our class. This is free play, however, sometimes it is good to have someone help you gradually develop your skills in a cooperative fashion. In this way you nourish each other and help each other to develop skills and you attain that much quicker. If Alex and I were to free play all the time , I would have fun and he would learn very slowly.
