To cut to the chase, I'm wondering if there are any passive movements (or later mobilities which I don't yet know of) which people recommend doing to improve the deep squat. Specifically, ankle/achilles mobility and for the knees. I do the stretch series. I do all the -ims. I also know which stretches help improve my shoulder ROM, hip ROM, and thoracic ROM. For my shoulders, I've found that im's from Foundation 2 for HBP do the trick; for thoracic I find the 'ear pressure pose' or knees behind head from TBs, always works wonders; for hips, the swivel hip, firelog and hero poses, and sitting in the swivel hip position, are sufficient. The other two areas of trouble have thus eluded me.
I recently have settled on the kneeling achilles stretch from the FSs, but I don't feel like it engages my achilles enough to where, as Coach puts it, I'm telling myself 'this sucks, but you can handle it'. Further, I do skier squats, and the twisting squats during my workouts, for the knees, but I feel excess pressure (re: not pain, but pressure as there is no limitation of ROM) around my right vastus medialis everytime I get up. I know that I had a microscopic bone spur there when in undergrad, but since it never limited my ROM and it only provides some discomfort occasionally I never had it removed. I know that the SLS progressions are a 'knee series', so to speak. But I'm looking for things to do when it's a rest day and I'm watching a movie or if I'm bored on vacation, to just keep the joints and tendons limber and to help expedite the improvement of ROM.
Thanks.
