Do I need to buy anything?
You are not required to purchase anything in order to participate.
We have Kimonos for rent $10 daily fee to cover cleaning cost.

How often should I train?
The answer to this question often baffles people because the truth is you should Always be training.
How is this possible? Well let me tell you that it’s all about mind set and mental skills. Do not just see this as a physical activity because Jiu-jitsu like any other martial art is a system of thought and expression.
Generally I advise people to start physical preparation at least 2-3 times weekly but that doesn’t mean you cannot watch and observe all the while learning more than actually participating.
Trust me when I say you need to do both and your development will always progress.
