Hey! Just an update on this. We finally got around to raising the strap bar tonight. (had it down low for our 6's and free hips)
IDK if it was the platform I was on, or my size, or the timing, but there was no way I could have gotten a knee during the counterswing so I went pancake on the abdomen and just helped guide in on the first few attempts and she got the idea on about the 3rd try, and by about the 6th try it was looking pretty good, and after another practice or two this particular girl will probably be able to take it to the real bar.
Thanks so much, my gut and memory told me it wasn't tremedously difficult or complicated but I appreciate the thoughtful responses and reinforcement.
So glad I found this site!
