Last night I was playing around and managed my first dropback without the liberator. In my shala few people do dropbacks at all because the custom is to do them only after you complete a full intermediate practice (yes, I know this is not the norm). Usually when I've done a full intermediate practice I'm wiped and tired and go straight to UD. My full intermediate practices have also been sporadic and inconsistent energy-wise, which may be why J hasn't pushed me to drop back.
I dropped to the liberator and then kept coming more and more forward for each one until I was off the liberator entirely. I hit the ground, quite thumpily (have to figure out how to deal with that impact and take it out of my shoulders) and rocked three times to come back up. Immediately banished the liberator and vowed never to use it for backbends again. Dropped back and came to standing several times sans-liberator to ingrain the memory of the movement. I'm dropping back! Euphoria!!
I will try to take a clip at some point to show the drop-thump. Been perusing others' videos and no one seems to have this crash-bang, so it might be a learning stage or something important technique-wise that I need to change.
