Instead, you want to weight your heels down.
It was my first attempt ever at 2 point, so it was a learning experience. When my leg slid back, it meant I had to put more weight in my heels, but I don't have someone on the ground to tell me as it happens so I gotta be my own instructor and find these things out when I go back and watch the videos.
At least now my leg is a smidge too far back... in my eyes, its better to work with than a chair seat!
I will be posting a lot of videos, so keep your eyes open!
