'sleeping raised foot thunderbolt posture'
how to roll back while the arm is behind the back?
any comments about this pose are welcome.
hope to hear from you,
wim
Yes, right … much too difficult for me, Wim. I would say “slough off the arm!” 
On the other hand, try folding the stretched leg (i.e. bend the knee) as you roll back over the arm. That’s what I saw them do in a small excerpt on youtube someplace.
dank je for the reply willem,
i don’t think i will slough of my arm just yet. 
i figured out that rolling over the arm is ok to do when not binding the foot. so for now i will practice it like that.
if anyone has any more insight in this pose please share.
thanks,
wim
