For those who have some interest in TaiChi, I highly recommend looking at the YouTube videos on TaiChiCentral.com. Ian Sinclair is a pretty amazing teacher and has an excellent lesson (lesson 4) on TaiChi Tuishou or Push Hands. He is a patient and thorough instructor and his videos have a nice relaxed sense of humor along with excellent instruction. His many videos vary in difficulty but he always finds a way to make it clear and insightful. Check it out for yourself. Here’s the Push Hands one.
