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。
