Study: Every Jiu Jitsu athlete studies moves. Remember this – ANY GIVEN HAS FOUR CRITICAL STAGES:

First- and precursors
Second – entry
Third – execution
Fourth (if the move should fail (and realistically the majority of your attempts will fail on someone your own size and level)) – /entrance to subsequent move

Only when you study moves in this four step pattern will you realize their depth and use that to succeed with them.
