Hey! So I came across this video and you can see in the beginning and the end the extreme active flexibility this woman has. It's amazing! My question is, in order to develop this type of control and strength, are pike and straddle leg lifts efficient? Or should I for example rest my leg as high as I can on a shelf and try to lift it from there? Any comments on how people in the contemporary dance community get to this levels would be appreciated. Thank you!
