Advice Needed on Full Camel

Photo via Benitasana, the awesome website of a yoga teacher.

Morning, all! So I just saw an awesome article about having a yoga pose-off in the park on Yogapedia that got me thinking about Full Camel.

Full Camel is a pose I think I will be able to pull off "eventually or in the future" (ha, Bikram dialogue moment!)... but I still have qualms about how to get into it. Anyone have suggestions?

How do you get from regular camel pose to full camel pose? Anyone know of any special stretches or backbend suggestions for improving flexibility in the low back to get into that more intense version of camel?

I'd love your suggestions, especially Bikram teacher readers out there. Thanks!

How do I get from the above photo to the one below? Camel pose. For the win!

Update: Check out Joslyn's guide to getting into the posture on Miss Fit Bliss. Totally going to try that! I'll let you know how it goes...
