I'd resigned myself to not getting my heels up in Kurmasana, when it happened I think I was more delighted than when I grabbed my heels in Kapo. It's always felt like that old hand trick.
Get your friend to put their hand flat on the table palm down, now have them curl their second finger under so the tip of the finger is touching their palm. Point to their little finger and ask them to wiggle it , no problem, now bet them twenty quid they can't move the next finger and point at the ring finger. It wont move, just wont move the tiniest bit. Collect your winnings and get the beers in.
That's how my feet felt every time I tried to raise my heels.
Thought my legs/knees might go flatter in Baddha konasana one day but not after six weeks off.
Not sure how to best explain it. Was it the Six weeks of Vinyasa Krama, the first evening practice in a long long while, or perhaps because i hadn't has such a sweaty practice since the Autumn?
