Every body is built differently with different abilities. Nijinsky doesn't have my body, and I don't have his. It may be hard for many people to even turn out to 180, but I can easily. I can take pictures with a digital camera if you would like.
I assure you I am not damaging or stressing my knees. My teachers are former principal dancers with Nederlander, Bolshoi, and SFB - both holding college degrees in anatomy. With my years with them and with other teachers I have never once been told that i am stressing my knees, even during private lessons.
Anyway, the post was aksing if there are alternative to stretching as I can push my feet up against a wall in the "frog" position and lift up my back without feeling a stretch in the groin area.[/i]
