I shared this on reddit, but I thought i'd put this here too

Half guard is my A game from the bottom and I put everything I know about the half guard and its variants into this series. In my opinion this is the most comprehensive series on the half guard to date.
I loosely defined half guard as any guard where the persons 1 leg is between mine, so this series covers the following: Knee shield half guard, the underhook, the dogfight, reverse de la riva, sit up guard, reverse half/backstep/jedi mind trick, waiter sweep position, entries to these half guard variants, and recovery from disadvantageous positions back to half guard. Of course I added a good 2 hours of narrated rolling at the end so you can see how I use these systems against resistance.
BJJ Fanatics were awesome in giving me complete control over how I made this series, which means I got to piece everything together exactly as I planned. There was actually some concern about the series being too large to put as a single product but I convinced them to keep it like that because each of the positions links to the other.
It took 3 days to shoot, and a few months for me to edit/order the clips exactly how I wanted them presented. Essentially I wanted to avoid some of the things that I often find frustrating about DVD's. Each chapter contains primary attacks from the chosen position, and then follow up attacks that you use depending on how your opponent reacts, this way you get to understand my mindset and hierarchy for when I use each move, rather than just a random collection of techniques that I use.
I have always found it frustrating when I am having a problem with a technique, and I have to sit through a good 2-3 hours of tape just to find the solution I am looking for. To work around this I have a troubleshooting section for each of the major positions, in which the title of the clip relates to the problem you are encountering. I thought of all the problems I encounter, and common problems my students have. E.g. say you are going for the underhook sweep but your opponent is hiding their leg so you can't apply the knee twist: There is a Troubleshooting section for underhook half guard, and in that there is a clip titled "Counter to hiding their leg 1". It should be very easy to locate that clip. Check out the DVD cover to get a better understanding of this.
Throughout the DVD there is a bunch of live footage of me doing the technique, so you can see it live, along with 2 hours + narrated rolling at the end.
The best thing about this series is that it all comes together as a system. Each of the techniques link so you should be able to constantly stay on the offence within the half guard. That said, I do also include when and how I would transition out of the half guard to other positions, such as single leg X guard, for which you can find my instructional on that through the Grapplers Guide.
I hope you all enjoy, and if you do, please recommend to all of your friends!
