At long last, I can safely say that this mobility is much, MUCH better and -- dare I say it -- mastered (if not, then quite close to it).
I'm using a 5lb. weight plate on the bar I'm using. It's taken a good three blocks to jump from the 1.25lb plates, however, I saw consistent progress when I jumped 1.25 lbs each week or two. Let me know if I have, in fact, conquered this 10-month long progression and can focus more on HS/PE2 and PE2-im (both of which I have already started due to boredom with tripod stands).
Thanks
