For the first time ever, you can learn the entire lapel guard system from its creator Keenan Cornelius.

The infamous worm guard made a debut in 2013 when Keenan started competing at black belt. For a few years previous to that the development began, but he held back to make a bigger impact when it mattered most.

In 2015 the 1st Worm Guard DVD was released and became a hit. That was the first time you could learn more than 2 hours of worm guard related techniques.

Now, in 2019 it is time for something colossal. 9 chapters, 9 HOURS of everything that makes the lapel guard system work for Keenan. Now anyone can learn all the details from setting up the first grips to getting the sweep or submission.

This app is just one of the ways to enjoy Keenan's Lapel Encyclopedia. It allows browsing, mobile viewing, making playlists, downloading videos and more.

This app is a platform to enjoy the Lapel Encyclopedia from the convenience of your smartphone. For you to develop a formidable guard SYSTEM, a guard that's increasingly hard to pass! See you in Chapter 1.

Seriously legit!

Keenan breaks down his unique guard play in a way that makes it easy to grasp by all skill levels! Everything is here in this app. The download feature is what I was hoping for the most as I travel a lot and don’t always have high quality internet to stream with, so with this app wormguard is going everywhere with me! Highly recommended for anyone into competitive Brazilian jiu-jitsu in the gi!

Great app to compliment the website

I have been drilling the lapel and worm techniques for a few months now, but the release of the lapel guard website and this app have made learning so much easier. All of the techniques are compiled in chapters which allows for easy review. The videos are of the highest quality production value and I love that the app also works perfectly in landscape mode on the iPad.

A must have

This is modern Jiu Jitsu at it’s finest. The techniques are ground breaking. The lapel guard system is incredibly efficient and more-so uber confusing for your opponent. The app makes it very convenient to dial in on specifics details anytime and any place.
