I haven't learned dance, but I will start school soon, and I have to learn it at school, especially splitting and asking questions. What are the skills? !
Face the wall and put your hands behind your ass. If it hurts, stick to it and push it in a little bit. It takes 15 minutes to get up again, and then relax properly. Otherwise it will hurt for a long time. Don't push too hard, lest you pull the vertical fork. If it hurts, stick to it. It takes 13 minutes to relax and practice the split. If it doesn't hurt, you have to endure it.
