I have always been impressed with how bad many (if not most) practitioners of jiu jitsu are at take downs--even when it comes to very basic wrestling take downs such as the double leg or single leg. This is especially true for those who made their way up the ranks while not competing and always starting from the knees--a pragmatic practice that nevertheless takes much of real life out of the roll. I agree with Josh Barnett that not learning take downs is problematic. After all, if I can't dictate where the fight goes, I may never make it to the ground! This is why learning self-defense and take downs (including Judo and wrestling) ought to be part of a basic jiu jitsu curriculum. No one should be an upper belt who doesn't at least know the basics enough to be able to explain them clearly to a beginner--or, at least that's my own opinion. But given the relationship between opinions and assholes, I won't beleaguer my point any more for present purposes! Just let it suffice to say for now that I have trained at gyms around the country and I have always been surprised with how many of them neglect the crucial art of the take down (either partly or entirely).
Luckily, the gym where I am training now has been taking take downs seriously. We have a former D1 wrestler who comes in to teach stand up on Saturdays before open mats. Plus, at least in the morning classes, we have been adding take downs to our warm ups and drills. One basic technique which seems to give people problems involves "running the pipe" from the single leg snatch. So, I thought I would not only dedicate a post to running the pipe, but I would also include some videos by Dan Gable, Justin Burroughs, and Barry Davis on the fundamentals of take downs more generally. I will treat this as an inagural post in a new series about take downs called Earn Your Way to the Ground. Per usual, I will pick a technique, comb the interwebs for some interesting and illuminating videos and compile them here! Watch, learn, and go train!
First, the videos about take downs more generally:
Second, an overview of the single leg more generally:
Finally, two different versions of the single leg--namely, the knee pinch (Primo) vs. the more open stance (Hilton). Both approaches are efficient. So, both should be drilled. I personally prefer using the knee pinch as my go to choice. But for people who prefer other options from the single leg snatch, the open stance is preferable.
