Everyone needs this in their library. Karel is an excellent instructor with decades of experience. Excellent details on the armbar.
Amazing Instructional! Next Level Wizardry!
Love your guys videos and I love the way Karel teaches very easy to understand and follow great instructor…
Silver Fox shows armbars from all sorts of positions. Two signature details that he uses which have stuck with me are the shotgun grip, which he would use every time with juji gatame, and the top lock for bottom armlocks. These two details along and the multiple ways he implements them is worth the price of admission.
Excellent instruction
Excellent instructional. (I guess) Everything you need to know about armbars.
Comprehensive and covers backup plan, entries and transitions really well
The silver fox is great. Arm bars from multiple positions and situations. Really improved that part of my game.
A good focused instructional for me on arm bars. I’m curious how this would compare against Danaher’s Enter the System.
This product is brilliant. A very thorough instructional and very well taught.
Great series - good points on grips and positioning.
Really good armbar instructional lots of depth and unique armabrs
Great armbars and mechanics from almost everywhere deliveressssssss
Silver fox is amazing teacher so many unique details will level up ur armbar game
Another Gold Medal for the Silver Fox! Opens your mind to Armbar possibilities. Especially if you are older and maybe not as limber as your opponents.
Awesome
Silver Fox is an excellent technician, this video is worth to have. Plus if you have any question about the video, you can ask Silver Fox live during his youtube live event, every friday !
As a new white belt. This video gaves great demonstrations of skills and key aspects for me to focus on and maintain through my journey in BJJ. Thank you Fox!
Contains stuff you likely haven't seen before but almost certainly should add to your game Oh also backup submitions, lots of them
I love the Silverfox’s smooth technique. From what I have seen so far he shows very good details. However, parts of it seem to be more difficult to implement than I thought. E.g I would have loved to see a few more entries to the split guard. Initially I wanted to give him 4 stars but this would not have been fair
Karel's material with Firas was fantastic, and this series goes even deeper. I'm especially a fan of the armpit grip and how he lands it so smoothly from a variety of positions. For context I also went through the 11h Danaher Armbar series (Enter the System) and some Dave Camarillo material, and this is *still* complementary. There are levels to mastery. Hope I'll get a chance to visit his gym someday, cheers from Japan!
Loved the details. I’ve seen him on Firas’ YouTube.
I’m a smaller guy and had trouble using arm bar against much larger opponents. The Arm Pit grip and Bolt Cutter have totally changed that. I use the bolt cutter every time I roll now. Cuts threw any grip GI or No GI. That alone is with the price of this DVD.
This is the **** :ok_hand:👏�:100: thanks silver fox for yr insights
Found Karel on YouTube dropping “gems” with Firas Zahabi. So, I had to get this instructional and it does not disappoint! Karel explains things very well and armbar perspective is levels above, I think this guy has a PhD in armbars or something. I’m glad I can get this perspective as a white belt.
