Man you guys are good!
Taking everything you all said into consideration I had the deepest, most fulfilling and cramp-free rabbit in a good long while.
I focused on really gripping my heels and realized I had not been keeping them close enough together during the pose when I was cramping and not getting a good stretch.
This time it all seemed to come together when I made a conscious effort to squeeze them together. Thanks so much for your input.
