Dao yin, which translates as "guiding and pulling", is the probably the oldest of the various traditional Chinese exercise systems. The full body sequence presented here is a series of simple stretches and mobilisations that we use to warm up for tai chi practice.
I've included them in the program as warm ups for the remedial sequences and to limber up before practice sessions or long gigs, you'll see references to them throughout the program. For now it's best to learn the full set, you'll only notice the cumulative effect once you've done them like this a few times. They don't need to be done in this sequence though, eventually you'll have a series of exercises that you can pick from depending on your needs.
