Okay, tell me if I'm wrong with this one...you swing both legs, and the feet kind of come in and around, so that they "meet" in the middle (or look like they do) and then up, and by then your legs are all set up to go into the V-splits?
If this be the case, then this is what I understand of it: You gotta have your knees together at first, and your feet up...push both feet out, knees together (this will feel really awkward), and as you bring them down, open your knees, so that when your feet continue their circle upwards, you can see them, if you're an audience! And as they come up (and look like they're meeting in between, there) and reach the top of the circle again where they started, your knees are already open, so you can just continue with the momentum into a V-split...as far as you can! 🥂
I recommend finding a few videos of it, if you can (Try Leigh ann? She's got some awesome floor work!) and just try to slow it down, work it out in your head. That's how I figure out most moves like this! I could tell you how a lot of moves work, without even being able to do them! Problem with that, though, is I don't understand transitions or anything...I tend to work off an ideal.
Perhaps I'll practice them and put up a video for you? If that is the move you're looking for! 🥂
