I've been training in muay thai for about 8 months now, I got my yellow belt about a month ago and have been doing a lot of complex combinations, sparring, clinch work, etc. Today we were doing leg kicks, body hooks, liver shots into left hooks, and then head kicks. A lot of the guys get their kicks up easy, but I need to work on my flexibility. I tend to go back to my Kenpo roots and snap the leg occasionally, which I think works in a lot of cases. My questions is does anyone know good ways to get that hamstring area flexible enough to get head kick height easily? Hopefully this is the right section, if not sorry.
