I've always tended to do a crossed leg jump back. In fact, up until recently I wasn't aware there was an uncrossed version. I don't mean lifting up with the legs straight and then bringing them in, crossing them and taking them back through, but this.
'From dandasana, exhale, hold your breath, and lift your body to dandasana-utpluthi. bend your knees, keeping your feet together. Do not cross your legs. Take a short inhalation, balance yourself nicely by leaning forward a little and keeping your head down, and hurtle backward smoothly, close to the ground. Land on your big toes.' S. Ramaswami, The Complete book of Vinyasa Yoga p69-70
'Keep your feet together'
'Do not cross them'
I'd never noticed this before, saw the pictures and did my Jump back. But then I noticed something strange about the picture, the ankles aren't crossed!!! I tried it this morning, no way not even close, impossible, can't be done. Checked Youtube, nothing there. Does anyone do it this way or has seen it done in the Shala or on video? If so please let me know and send me links.
Thanks to niall for this link to a video of Olaf doing this style of jump back. I love it and will be working on this over the next couple of weeks. I have, what, two and a half months left to nail it.
Luckily the Jump back/through doesn't play a huge role in VK (and it's hardly a dogmatic system, adaption is it's middle word). You tend to have a jump through to Dandasana at the start of most (but not all sequences), Seated Sequence, Asymmetric, Lotus etc. Then you tend to have a return series which is basically the jump back to downward facing dog (depending on the series).
Still it would be nice if I could work it out.
And how about the Jump through? Well it's the straight leg version. I've always done the crossed leg Kino style jump through. I learned the Straight leg version a while back (blindfolded) but never really practiced it that much so have forgotten it again. Will have to go back to Blocks and socks on the bathroom floor.
Flicking through the book I came across a Jump through sequence I hadn't really noticed before. This is in Chapter 11 Visesha Vinyasa Kramas. This chapter contains some miscellaneous subroutines. The Chanted Sun salutation is in it, as is the Anjaneyasana/Hanumanasana subroutine along with some others. Buried in there is this little Jump through subroutine that includes all kinds of Jumps. Jump through (and then back) to Dandasana, to lolasana, to Vajrasana. Jumping through one leg bent, jumping though in half-lotus, Durvasana Bhuju, Baksana, handstand, Mayurasana, Astavakasana, Ekapada sirsasana, just about every kind of jump through variation. Curious routine and I can't wait to try it, that's my Easter egg.
Interestingly in Mark Singleton's Yoga Body, a fascinating but quite devastating book by the way, there is a group of pictures from Kuvalayananda's Yougik Sangh Vyayam 1936, that appears to show the same feet together, uncrossed jump back. What's that all about.
