Hello guys! I have a question regarding a movement from the 116 wooden dummy form. A lot of the wooden dummy movements are self-explanatory, however there is one movement in there that I have no idea what the application would be. It's the "tok-sau", where you slap and lift up the left and right upper arms with your palms from below the arms. If you look at the video below, you'll see it at 0:09, 0:18, 0:24, 0:48, and 0:59.
