In response to Wanda's Tai Chi q's, I might have sent 1 partial reply because my sleeve hit the mouse before I was done.
There are many forms of Tai Chi & Chi Gung that have long forms & short forms (the number of movements in a set). Of course short form may be easier to learn in the beginning because there are less movement sequences in the set. Yang form is the most prevalent taught in the US & fairly easy to learn as well as being universelly effective for many ailments humans accumulate over the years. I think videos are great to memory jog at home, but highly recommend in person group classes because of the community spirit, support & friendship if it is close enough for you to get to regularly. Also the group energy field is enhanced when done together. This is why Tai Chi & Chi Gung are practiced in groups in China..healing is greatly enhanced in group settings. People attracted to Tai Chi are like people attracted to Icelandics, so you could make quite a few long terms friends this way. Kaaren
