Keenan Cornelius has another weird guard technique to teach.
He calls it the Mantis guard and it involves making a grip on your own shin (or pants).
Watch the video and see if this works for you.
He teaches two ways of sweeping the opponent with variations for the waiter sweep and the x-guard.
old school position in brazil..
this technique is very interesting. The first time i tried the de la riva or reversed de la riva, by holding my own leg i noticed the partner's leg was stuck. This follow up is great and i have to remember it to use it.
