Thank you Coach for the new SL progressions.
Perhaps the new progressions are an evolution toward our end game, namely the slde lever also commonly called the human flag; however I was really starting to like the Supermans. I'm still stuck on PE1, but I felt the road to mastering them was good for total spinal health and the whole posterior chain. Doing them reminded me of a McGill article I read some time ago about spinal strength endurance being an important factor in good spine health and being pain free. I haven't had any back issues since I started practicing the Supermans.
Any thoughts on whether it makes sense to stick w/ the Supermans in their own right outside of my gb practice sessions? Would it be gb blasphemy if I wanted to Master them before starting the new series of progressions?
