Hi guys, so lemme give you some quick back story on me to put things into perspective. I am 44 years old, spent a lot of time in my mid - late 20s learning Chinese Kenpo. I've always had some issues with throwing a good side kick like my hips dont seem to want to let me legs go straight out. My instructor wasnt worried about it b/c I if changed the angle just slightly it was fine and it never impacted anything else. Now fast forward almost 20 years, I've been horribly inactive, had a desk job for the past 5 years. I just got my kids into TKD and decided to take it with them b/c I'm sick of the life I'd been living and wanted to feel better and get fit again. OMG... the lack of flexibility for side kicks, roundhouse (wheel) kicks, butterfly stretches, is insanely poor. If I sit down and try to spread my legs out as far to the left and right as I can, I can get maybe 35 - 40 degrees between them before it feels like I just cant push it any further. Many of the stretches that I have read about to train for side splits hit the areas that I am in need of work on but I am so far from where I need to be on them that they are almost ineffective. When I do manage to get a decently wide stance for a horse stance, I can feel my hips popping sometimes. I know you guys aren't doctors or anything but I'm hoping for some insight on how to push past this safely and regain my flexibility. I really want to continue in my training. Thanks ahead of time for any pointers / suggestions. Any and all are welcome.
