If you
don't have flexibility then you won't have the kick. As obvious as it
sounds, people just don't do enough stretching, even when they know
they should. So I will say it once again, "Stretch." Figure out
which muscles are involved with each kick you are trying to improve and
take action by stretching. There are two specific ways of stretching,
the first is for warming up and is done before a workout to decrease
chance of injury (hold for about 9 seconds each stretch). The other is
for increasing flexibility, which is done after the workout to improve
the stretch. These stretches
you would hold for longer periods of time,
from 10-20 minutes.
Isometric stretching is very important as well. For isometric stretching, For example, go into the splits or any other stretch and hold the stretch, flex all the muscles in that area and hold for minimum 30 sec. This should be done after a heavy workout. After holding the stretch, release and sink into it comfortably. The longer the hold the better.
One of the most important parts of Stretching is something that you might be able to guess, yep, you got it, "Nutrition." See our Health section or the Alkalarian diet at www.ninjagreens.com for more information.
Naturally its best to just start stretching. If you would like to speed up the process, you should start implementing some of these key strategies stated on this page.Another great technique for stretching and becoming super flexible is Dynamic stretching. What you do is every morning upon waking AND / OR before every workout, do 10 - 20 straight leg kicks. Do sets for front kicks, side kicks and back kicks. Remember, these are straight leg kicks meaning you just swing the kick as high as comfortable until loose.
You can read the Kicking e-book for more information on Stretching and will help your flexibility all around.
