For an interesting read about subjects that cross the spectrum of martial arts training, from traditional Jiu-Juitsu to BJJ, to MMA, and self-defense, Jiu-Jitsu Sensei is a great site to check out.
Sensei Lori O’Connell posts from the unique perspective of an active MMA competitor, active traditional instructor, and being north of my border, in Canada.
Her current post is showing a Kali knife defense flow drill. Click on the picture or here to check it out.
UPDATE: Forgot to mention that you can follow Sensei O’Connell on Twitter, too.
