I have since moved on from PL and am learning MMA, including jiujitsu, boxing, various forms of kicking, and good old wrastlin'. I am stiff and inflexible, both from maintaining only the requisite flexibility for PL and also from being stuck behind a desk for the last three years (which ends tomorrow! woot!).
Has anyone made this change, and, if so, how did your flexibility training come along? Right now, kicking at waist level is literally painful because of adductor and hamstring inflexibility. And I lack the ability to stretch "into my hips," the way they had us do in tae kwon do when I was a teenager; I'm all hunched over with any effort in stretching the posterior chain.
Thanks for your feedback.
