The very first thing to keep in mind if you are wondering about How To Improve Ballet Turnout, is that you cannot force it. Trying to force your turnout will only result in a very bad "roll" and it will make things worse.
You also have to keep in mind that your turnout starts right in the hips and you must not simply try and force your feet wider. Do exercises that will help you to really turn out from your hips. Go to the lens How To Improve Ballet Turnout for a good video to show you the exercises. It is much easier to demonstrate them than to try and explain them.
Another important thing to remember is, you cannot improve any other ballet technique before you have sorted out your turnout as it is the basis of ballet. This does not mean you do not have to work on anything else in your ballet, it only means that you have to keep in mind that the turnout is important. Always be sure not to force it and work on it steadily.
So, if you have the problem of bad ballet turnout or if you are wondering what to do if you have no turnout in ballet, go to How To Improve Your Ballet Turnout and get some help.
