I have always liked Danaher’s analysis on this sweep in his other instructional. It adds so many extra layers to a dense topic when he can do a full instructional on just one move. Masterclass!
Absolutely amazing as always from John
As always, amazing details.
Great instructional on the Sumi Gaeshi sweep. As always John breaks it down in a way that is clear, understandable, and applicable during live training. Since watching the video I have been using concepts and techniques from this instructional to be able to utilize the Sumi Gaeshi a lot more often and make it a substantial part of my sweeping arsenal.
Great insights on a move I use a lot, and look forward to adding the little details John has showed.
I’m a wrestler starting to learn jiu jitsu this has been a huge help!
Excelentes aulas, muito bom.
A great in-depth look at one of the most versatile sweeps. Great thesis
The Best sweep from open guard with the Best instructor.
Comprehensive study here as usual
Amazing details. I was able to apply the material and have almost immediate success. Excellent instructor.
John Danaher Explanations and the verbage he uses to break down all the techniques in the moves , makes it easy to learn. THis is the future of learning.
Been using some of this already in classes,definitely a fan of the half butterfly guard and will continue to build on it.
Great details
Excellent, my teammates and I have been going through after class. Tons of information from Danaher, I try to pick one thing each time, as to not get overwhelmed. Results from day one.
A great refresher for me about the position, learnt some important things about transitions for sumi gaeshi and super cool detail about excution from standing (aka great counter to single leg in the gi)
Terrific. Thanks JD. I was waiting for this long time🤗. Extremely helpful.
The butterfly guard is good to know, explained well here.
Easy to follow and understand
バタフライスイープが上手になりました。
Excellent stuff
Danaher is always super helpful and knowledgeable
Super
Curso completo, com efetiva compreensão da mecânica da guarda-borboleta. Vai além da mera coleção de posições.
Strong guard
Simple and strong guard
Great Video!
This isn't just a simple butterfly sweep; it’s a comprehensive system executable from standing and various guard positions. Danaher’s mechanical insights transform the Sumi Gaeshi into a versatile, high-percentage attack for any grappling scenario.
I was able to hit this move several times in training within a week of watching the tutorial
The details and insight on the technique is so profound. This open my game up so much more making jujitsu more lovable than it already is for me.
deja el concepto muy claro, excelente todoooo!!
Simply the best
Great details as always

This is classic Danaher video series. Butterfly guard is my favorite.
Well organized review of the butterfly guard. Lots of details Great for beginners and advanced BJJ practitioners
I really like the explaing of outcomes.
It uses the live scanio to really help.
Another word class instructional from the master of the position. The sumi gaeshi sweep is one of the most versatile in the sport. Master obtaining it from every position.
World class instructional as usual. The sumi gaeshi is one of the most versatile sweeps in jiujitsu
My butterfly really improving
It is the best begiining for butterfly guards.
Anything John does is outstanding, I’ve just received my purple belt and couldn’t have done it without his instructionals, this simplifies the butterfly sweep so I could do it the next day in training . Oss
This has become my favorite series by far
As usual for me I can see why he hes the instructor of black belts Never has something you learn in your first week of BJJ been broken down and explained so well Making the implicit, explicit
John debugged my butterfly guard and it feels great. Like always John showed what the underlying problem was and how to understand it fundamentally. It’s the little things that make a big difference when it comes to pulling off moves on a high level opponent. Highly recommended.
In depth and excellent as always.
Complete and as usual, covering the specifics to make the butterfly guard a big deal
