Here's a Lucas Leite highlight video to kick off the #bjj tag here on Hubski. Leite is a highly decorated Brazilian jiu jitsu competitor, famous for his half guard skills.
Brazilian jiu jitsu is a martial art, combat sport and self defence system focusing on grappling and ground fighting. Personally, I don't particularly like comparing it to other martial arts (other than perhaps judo), because unlike most traditional martial arts it is a lot more focused on active resistance and sparring.
This Lucas Leite highlight really resonates with me, because the half-guard is my favourite go-to position, and the first parts of the highlight looks identical to my own game (although he does it a lot better).
