Trying to get my lotus tighter and deeper and work on bringing it in closer to my armpits. Also trying to slow my descent . The main problem though, seems to be that my arms collapse as my lotus comes down past parallel with the mat, such that my shoulders are almost resting on my hands. By the time I land it I'm all squished up, which doesn't give me much chance to generate any movement back up.
From the YouTube videos I've seen the head and chest come through at the last moment just as you land. Going back up you seem to begin there, the reversal of that movement seems to begin to generate some motion to help you up. Need to create more space to move.
