Bit of background: I'm inflexible. Have been since puberty, I suppose. There's been various times in my life where I've taken up a regiment of regular static stretching, with mixed results - never really achieved what I would call flexibility. And it's never taken me long to get back to being very inflexible when I stop. Getting back into karate a few year ago has helped, but generally I can't even touch my toes unless I've been stretching pretty regularly for a week or two. A month or so ago, with the help of this forum, I discovered that my DL form was causing me lower back pain, and decided that my lack of flexibility was a major contributor to my poor DL form. So, I decided to prioritize improving flexibility for a while. The end goal is really to injury-proof myself better. I've read Flexible Steel and liked the concepts, so I took up doing the "escape your fighting stance" sequence, along with KB good mornings. Today marks the end of week 4 of doing the sequence 4x a week. Figured that's a good milestone to put down some thoughts about it. First off, it's a time-consuming sequence. It takes me about 40 minutes to get through it all, so it doesn't leave room for a lot of other stuff when you're trying to keep your sessions to an hour. Stuff that I notice: I've certainly gotten better at the movements of the sequence. Initially I had a very hard time getting my hip (right side in particular) to the floor in the arm bar, that's coming pretty easy now. Initially the tactical frog sequence was really uncomfortable, and it completely wiped out my hips - on day one, it made me so wobbly that I didn't think I would make it through the goblet squats. I can get a lot deeper into the frog now, though I don't have an objective measurement. And my hips don't feel so tired afterwards. Have improved the depth in the kneeling lunch. My standing toe touch is as good as it's ever been - which is still not all that good. I can get my second knuckle to the ground fairly easily, and can get the first knuckle to the ground if I work at it for a bit. I think mission accomplished on improving my DL form - a little more hamstring flexibility is helping me get my knees out of the way, no back pain for the last couple weeks. Interestingly, doesn't feel like my seated toe touch has improved much. Haven't noticed a benefit in karate, but my training there has been spotty over the last month - really need things to get normal again before passing judgement. The goblet squat in my S&S warmup feels easier, particularly with the 40 - that use to stress my upper back a little, I don't feel that anymore. Not sure if that's due to mobility, or just getting stronger. I'm not injury-proof yet. I still appear to be capable of getting hurt. What next? I'm enjoying it enough that I'll stick with the 4x a week for another 4 weeks, see where it takes me. I've recently added in KB pullovers, try to improve my overhead mobility too - and I'm experiencing the same kind of initial growing pains with that movement right now. Might try to start doing some front splits work if I can find a slot in my schedule. I've heard people say that acquiring flexibility is a long journey, but once you have it, it's easier to maintain. Hopefully my interest in the acquiring part holds out long enough to find out. Onwards.
