Robert Miller from TKRIblog put together a great piece on the hurdler stretch. This is a stretch I gave up long ago but when I was checking up on the blog I realized many people may still be doing this. Not just martial artists, which is Robert’s focus.
But back in my MA days…we did this religiously. So true. And yes, as Robert discusses, we were taught that you couldn’t do a proper roundhouse without it.
This is the one where you sit on the ground with one leg bent BEHIND you and fully flexed. The other leg, straight out in front of you you bend over to stretch the hamstrings. We used to also lean over the bent knee for some reason…
If you are stubbornly clinging to this dinosaur of bad stretches then you must read Robert’s article: Regarding Hurdler’s Stretch and Kicking
He gives a good example of something that we need to do in our strength training and that we too often fail to do: A Cost Benefit Analysis:
Most of us have either trained with someone, or can imagine someone, who for no lack of effort, does not have the most impressive roundhouse kick in the world (due to flexibility issues), but who is still vigorously participating in karate Now imagine a different person who has painful, unstable knees, who because of his knees is unable to rapidly move laterally in kumite, is unable to kick at all without pain, is unable to dart in and out, unable to lift, throw or sweep. Which person has the greater handicap? I know this is an extreme example ( I have trained with people in both categories), but I use it to illustrate the point that even if it were the case that in order to perform roundhouse kick well one needed to do hurdlers stretches, the potential cost to the rest of one’s karate may be too high. Hyper-focusing on one skill can cause one to lose sight “of the forest for the trees”.
I’d like to point out also, that the way most people go about stretching their hamstrings ends up transferring most of the stretch to the more extensible fibers of the lumbar. That is, they bend forward at the lower back instead of flexing the hips. In this scenario the lumbar tissues will simply stretch before the hamstring.
For this reason, the popular practice of placing a leg up on a bench in front of you and bending over it is actually a fairly poor hamstring stretch. A comparable lying version of that is to lie down you your back and use a towel or strap to pull the working leg up. This keeps the lower back straight and promotes a better stretch of the hamstring.
This all begs the question of whether “tight hammies” are really the problem they have been traditionally made out to be.
