Thank you! It’s hard to explain things over the internet sometimes so I’m glad my posts make sense.
I drill/practice/maintain turn out by breaking down steps in the mirror or doing easier dances like trad sets or light jigs to focus on foot placement. Always make sure you’re turning out your entire leg, rotating your leg outwards from your hip socket rather than your ankle joint. Your knees should be facing away from each other when you turn out, not just your feet. It also helps some people to think about pushing their heels forward in order to keep their legs turned out through a whole dance.
The frog stretch (on your back, not laying on your stomach) can help you strengthen the muscles that you need to use to rotate your hips outwards. If you have access to a ballet class, the barre portion of the class has great turn out exercises. I got to take ballet in college, so I go through the barre exercises I learned to work on my turn out but I’d only suggest doing that if you can learn them from a teacher (rather than on the internet). Also there’s an exercise that I know as clams that are shown here http://www.youtube.com/watch?v=ML9pMqD1yVc
Your turnout won’t improve drastically overnight, it’s a time-consuming process that will take patience but if you keep drilling and focus on technique you will see improvement.
