One of the best instructionals I have ever seen. It is comprehensive and detailed, yet digestible. It works great for both beginners and more advanced players. The 4-part (short summary/"reference book" of the previous parts) is something I would make mandatory for all instructionals.
Quality instruction. One touch I really loved was the short summarys in chapter 4. I highly recommend this instructional.
Great explanation of how to make your guard more offensive for a smaller size athlete
closing the circuit for better entry into the clamp guard.
Great teacher and a really well designed system
Great course on the clamp guard loved it learned a lot
This guard feels so natural to me. Being a skinny guy as well, I can clearly see why Danaher would show this early on to Glick. All through the program my mind would come up with what-if's and almost every time the following video would address it directly. It was uncanny. The reason I am taking the time to write this review however, is the execute summary Glick puts together in the last module. He essentially distills down the entire program into snippets to show the techniques without explanation for quick review. This is spectacular. I will likely buy the other Under Pressure program simply because of this structure. If BJJFanatics reads this, you might push all instructors to add this feature (especially Danaher, lol)
Helpful for diversifying my guard game. Very thorough instructional.
getting in to the clamp guard. various ways of getting there.
He shows details the clamp guard and how to get to the clamp guard from any position. Clamp guard is a great position to get submissions. He also shows submissions from the clamp guard. Great video
It's like watching Danaher explain jiujitsu without all the yawning.
Gives some great tools to punish a lot of extreme forward pressure.
Incredible instruction for smaller competitors.
Big fan this was great
Good details and very informative
I was getting crushed in closed guard and during half guard. Very helpful against pressure passers.
incredibly articulated and explained. In-Depth and covers every angle and situation.
The most detailed tutorial on Clamp Guard. Brian's explanations are really easy to understand.
love this instructional. Everything Brian does is pure gold
Good stuff on the clamp, love professor Glick’s content
This is the first instructional from Brian Glick I bought, and it is up to my expectations (after following him on the social media). His explanations are very clear, he is a great teacher. The details are not overwhelming, and the instructions are easy to understand and remember.
use this combination to get this setup
This is a great check point position to my game
Great instructional highly recommend it.
Brian Glick is the answer to the getting smashed by bigger younger opponents. I love Brian’s instructionals.
I love this video. As a 40-year old, slender white belt, Brian's techniques fit me like a glove.
I first heard about the clamp from Danaher's instructionals. This is a deep dive into the clamp that can become an entire bottom game system. Highly recommend.
Brian explains things in a simple and structured formula. Works on the mats.
If you're built more like a librarian than power lifter you will find this very helpful. As an older skinny grappler I felt like this instructional was made just for me. Brian is the king of skinny guy BJJ.
Sweet guard retention principles
If you’re interested in the clamp guard or the Williams guard then this instructional is for you. It’s a wealth of information on clamp guard entries and what to do once you get there.
Second instructional from Glick, and he's so knowledgeable.
An excellent instructional on the clamp guard.
great details
I first learned about the clamp from Danaher this is a deep dive into the position by one of his top students.
very in depth
If you're interested in playing the clamp guard then this instructional has everything you need to know to develop a solid bottom game from this position. Highly recommend
Great instructional. This video will give you a nice game plan for controlling and then submitting your opponent. You will find this video simple to implement into your game.
Great material for the older; and, or, smaller person.
Brian Glick breaks things down in an easy to understand way, and the clamp was a great place for me to continue building my guard.
very practical. worth watching with the side scissor video.
This position is taught early on in your training but never reinforced Lifesaver
love Brian Glick. His teaching style matches perfectly with my slow working brain.
Great explanation for everyone
I think the clamp guard is highly undervalued. Brian's clamp guard video was one of my first BJJFanatics purchases. I will admit that the clamp was a difficult position for me to get into when I first started BJJ as I'm older and lack flexibility. I abandoned the clamp guard for a while and worked on my bottom half guard game circa Danaher's Half Guard "Ageless" videos and discovered that the clamp was more easy to get into from half guard or low knee shield as demonstrated so clearly in Brian's instructional, since I was already on my side. After re-visiting Brian's instructions I have been able to get into the position more often and got several submissions from the clamp guard position this week during live rolling. Often I get a *** look from my partners while in the guard or submitting them! Thanks Brian!
very smart, easy and clear instructions.
As an older guy trying to maintain connection and make use of my old man isometric endurance strength, this focus on the clamp seems ideal for my game.
very informative and helpful explanation of the clamp. this is a great video to aid in dealing with heavy pressure.
This is a fairly common position easily explained. Will help with controlling bigger opponents and finishing them.
great details for smaller weaker players
