PNF is a method of stretching. Basically, you tighten the muscle group, relax and stretch deeper into it. Seriously though, be careful if you use a partner. http://www.thestretchinghandbook.com...stretching.php
I googled and found it, after a while. Thank me by giving me tons of rep.
Read all the articles (there's many) and you'll know some ****. It is real siimilar to what I do and I kick high and only stretch if I'm injured.
"The problem was that the body alignment that worked for a given kick when it was aimed low (as in original Okinawan karate) did not work when the kick was aimed high—did not work, that is, unless one had an extraordinary range of motion in the hips and lower back joints. (The high kicks that appeal so much to young people were introduced into karate by Yoshitaka Funakoshi, son of Gichin Funakoshi, without any attention to whether they made sense in combat [Draeger 1974, p.134].)
Luckily I met Mac Mierzejewski, the author of Power High Kicks with No Warm-Up!, a knock-down karate fighter and instructor who also studied at AWF. He was less flexible than me, but he could throw any kick higher than I could, with knockout power, and without any prestretching.
During our individual workouts he taught me how to align the body for great height and power in the kicks without having to reach the limits of one's range of motion in the hip joints. He had to show me the “little” details of kicking techniques that let you kick high and with power without warm-up! As a bonus, these same little details reduce your chance of injury."
Thanks guys, a very helpful thread so far. I've got lots of links to browse tonight.
