Something to get the chi flowing
If you’re looking for some new warm ups to practice before Tai Chi then here Chen Zhenglei demonstrates some really nice ones. Notice that he’s using his whole body, including the dantien and legs to do each one, even the first one which looks like it’s only about the wrists. So, as well as being a good warm up for the joints, which must be free of tension, they’re also a good way to practice whole body movement.
