After a week of "super clubs" in Ibiza my son busts his version of Eka Pada in a "Trapstar" hat and "Nike Huarache" trainers. While the attire is pretty cool, it is not recommended with this yoga pose. :-)
I have never heard the tip about taking the calf flesh out before-nor the mention of lifting the thighs-Kino always give useful information in her short clips. It took me a long time to get the hand/foot grip correct and my feet most definitely do not touch the floor ;-)
As I have just started practising to the end of the intermediate series, I have been on the look out for some video clips. I came across Sri Pattabhi Jois teaching this section. Fascinating to watch and lovely to hear his calm, gentle voice teaching the practice. I hasten to add my version of the intermediate series vaguely resembles these. Yogis... practice, practice, practice!!!
