I’m trying to learn to coil on the rear leg so I can help my boys with feel/mechanic but when I turn my back right pocket it feels like it’s all turning in the outside of my ankle. Is that normal? I’ve been trying it off of one leg and weightless front foot. I’ve noticed my back knee also sometimes moving behind my foot slightly. I’ve seen my son do it too, so I know I’m translating something wrong, if that isn’t right. Feels like a dumb question, but dumber not to get the answer.
