I constantly shift around on my feet and use a lot of body language. I never used to do it. I think I picked it up from trick kite flying where you are alternating between powered flight (regular forward wind powered flight) and stall maneuvers, spins, flips, floating (tricks) where you use your whole body to "talk" to the kite.

Now that I'm actually practicing IMAC basic sequence, my concentration level is way up. I probably do all kinds of goofy stuff on the flight line.
