Observation: The model of development in Jiu jitsu ought always to be as as possible to the classical model of development in science – of the interaction of hypothesis, and observation and assessment of results in a never ending rotation that gives provisional but increasingly better answers to the questions you ask. When it comes to asses the worth of given moves, the merits of your training program, your performance of technique and tactics, nothing beats observation. As an athlete you must keenly observe your performances and make based in the feedback your eyes you. Training in itself is is the most important thing in the short term, but for long term almost as important is observation and assessment of that training that allows you to bring the results of today’s workout to ’s workout so that a compounding effect can be attained – only then can you grow to the that you aspire to.
