You will NOT find a more highly functional, readily transferable and tactically thought out LEO ground program or systematic approach anywhere in the world.

The ISR Matrix Horizontal Core was designed by LEO for LEO with the specific intent to inetgarte morally and legally strategies and tactics into a systematic approach in instruction and training. The ISR Matrix Horizontal Core brings the use of force spectrum, tool retention and deployment and the unique aspects of the profession right to the center of its training method and teaching process.

If you are active LEO looking for an LEO specific ground program, don't miss it!

Head control: There is a reason why they classify us as vertebrates - our spines are the center of our body. On top of that spine is our head. The spine is the longest lever in the human body. The head is at the end of that lever. If you control the head you can exert tremendous leverage that can be used to control the whole body. Look for opportunities to control the head - many are pretty obvious but some are more subtle. Understand that you can exert pressure on the head in both linear (eg snap down) and circular (eg crossface) directions - be sure to use both. Understanding Jiu jitsu is to a large degree, understanding the human body and its essential nature. Our spines largely define our physical lives - make sure your Jiu jitsu reflects this fundamental fact

Super Interesting 18 Warm-up Exercises - 🥋 Judo Spirit 🥋

In a game where control is everything - using frames to prevent an opponent from establishing controlling grips and position is a huge part of your development. The centerpiece of your frames will always be the link between your knees and elbows. The closer your opponent gets to you - the closer your knees and elbows need to be together

When you’re the more experienced or bigger partner - start in bottom position with disadvantage: We all have a wide variety of training partners. Inevitably there will be big variations in size and skill level among them - so don’t treat them all the same. When you are more experienced or bigger - don’t start neutral as you would for someone your own size or skill level - start with some form of disadvantage so you get more out of the session and work skills you might not otherwise work and at the same time make it more competitive. When you do this you can be in a room full of small white belts and still get a good workout. It’s not about who you beat in the gym - it’s about beating who you were yesterday - and starting with disadvantage is the best way to do this when training with people you already know you can easily beat.

When you’re starting on the path to back control mastery - focus on the upper body first: The back is the most dominant position in a grappling match without striking. Nothing else creates such a mismatch between the control and submission opportunities of the attacker vs the defender. The SCORE comes from the legs - getting your two legs hooked into an opponents hips is what creates the score. However, the real world control comes from maintaining chest to back connection with or without the legs. When you first begin the back game - focus on the upper body connection first and foremost. You can always get the hooks in later to score. Use your arms in seatbelt or double under control to form a tight initial connection and create a strangle threat. As you get more advanced you’ll find there are ways you can get legs in first without conventional upper body connection but they aren’t the best place to start since you’ll be using those far less than conventional methods. Here, Gordon Ryan, a true master of back control, uses a safety first upper body connection to secure himself in a winning position, knowing that once this is done, getting the legs in later will be relatively easy
