Well, maybe not so much secret and maybe not even absolutely necessary, but definitely f^*kin' cool. Yeah, we totally misled you. But, you deserved that and, deep down, we both knew this.
Sambo, or самбо, as the cool kids call it, is badass Russian grappling. We've gone through this many times before, so, this time around, we'll spare you the background. DSTRYR/SG's secret Sambo weapon, Martin Roy, gave us the heads up on this short, but sweet and very recent, clip. It features takedown instruction from Sambo Master, Vadim Kolganov. in particular, it's a very cool single leg trip that leads in to an armbar sub. Although it's visibly akin to collegiate wrestling and judo technique (and BJJ), it's execution, to us, is all Sambo and it's very unique.
