Long ago I had a comfortable full side split. I could comfortably drop to a full split with hardly any warmup and still had it into my 30s. Because I switched from TKD to more practical self-defense work I let that flexibility disappear. I'm a solid two and a half feet away from full split. In those old TKD days I was a head kicker. I competed a lot and now I'm missing that. I want to compete again and I want my flexibility back. The problem is that I'm making no gains at all. If I told you my age you would say that's my problem but I don't give a crap about my age. I'm still fast, I still have skill, I'm willing to work as hard as anybody and I'm not dead yet. I'm currently doing dynamic stretching in the mornings and before a workout. I'm doing PNF/isometric stretching in the evenings three days a week and I'm doing static/relaxed stretching during cool down. And, I'm giving reasonable recovery time. Still, zero gain. Anybody got some magic that's worked for them? Thanks.
