  This was my first Brian Glick instructional and I was not disappointed! He really is like Danaher without the 4 hour physics lecture. Gave me everything I needed to know about half butterfly with great details and a thorough explanation of how everything fits together

• Great Info! Great Teacher

  I'm no stranger too instructionals some are good and some can be bad and or hard to understand. I completely disagree with Coach Brian on being a bad teacher. The way he explains butterfly half guard improved my over all half guard immensely! His breakdown of concepts and details is next level. I can't wait to purchase his clamp instructional and really get dangerous with my half guard game. Great job Brian! Thanks BJJ Fanatics and Bernardo you are my hero!

• Excellent series. Well taught

  Professor Glick is an excellent teacher and conveys complex ideas in easy-to-understand ways. Really impressed with this one. It's helpful to see a slower, smaller, less athletic guy review guard concepts.

• the glick clicks

  Prof Glick’s content is absolutely a corner stone to your bjj mastery. His detailed instruction never drags on, and yet manages to touch on the finer points of any one detail. I’ve truly enjoyed his style, and the “executive summary” section is an absolute genius addition to the instructional market. Highly recommend.
