I've been working through the early stages of manna and have found something a little frustrating. I don't know if it is because I have a squishy belly or what, but...
In performing the tuck up it is (1) challenging to keep my knees together from floor to tucked position and (2) very difficult to bring my knees to my chest. Balance does not seem to be much of an issue, and it does not seem to have gotten much better since beginning these progressions. How do I earn the mobility to keep my knees together in the tucked position? And what appears to be the limiting factor in people who struggle with tucked compression?
Something that is concerning is the amount of compression gained out of the T-spine and not the L-spine+hips.
