Love this app. Roy dean is one of the best. Bjj practitioners out there.
I love Mr. Harris and Mr. Dean's style of Jiu-Jitsu, and this is a well taught review of the basic techniques found in BJJ. As a Gracie Jiu-Jitsu practitioner of eleven years I found myself returning to the basics and tweaking my technique! This is a great way to pass the time and in my opinion on of the best Jiu-Jitsu references available on the market for Android!
