Bjoern Friedrich is a BJJ Blackbelt under Roy Harris, and owner of Fighter-Fitness / Friedrich Jiu Jitsu Germany. Now even though this video is completely spoken in German, Mr. Friedrich was nice enough to include English subtitles. Let's just say this little tidbit was a success, very much unlike the soccer team.
So how do I know if I am making some major grappling mistakes? Mistakes that could get me hit in an MMA setting or self defense scenario. Well watch the video grapplers!
Friedrich demonstrates some common mistakes regarding the armbar and how to avoid them. He also shows the key to defend against punches while in the Guard.
