For years I'd been telling myself to start again, and this summer I finally did. Despite the fact that I felt like a newb wearing a white belt again, everything came back to me pretty quickly (technique, forms, etc).
However, my primary problem: flexibility. I'm not as flexible as I was when I was 11-12, etc. Since August, I've been stretching almost every day. I've seen my flexibility get a little better, but I'm seriously sore EVERY DAY. I'm wondering, is it even possible at my age (22) to significantly increase my flexibility, or am I destined to stay the same?
I see some of the higher belts (red, brown, black) in my class, who are in their 30s/40s and can't even kick above their waist-line. Luckily, I'm not that bad... but I think to really get where I want to go I'm going to need to become a lot more flexible. Is this possible? How can I do it other than stretch and hope for the best?
