I recommend you give this place a try.
I have been going to GB Santa Barbara for a few months now and I love it! The professors are amazing, they are good at not only teaching the techniques, but also explaining why you are doing what you are doing (there is a lot of strategy involved). They teach in a way that will help you in competitions as well as practically if you are forced to react in an actual fight. They are very experienced and give you personalized tips throughout the class.
I did the introductory class with Coach Ighor and he was great. He really showed me a lot of moves and demonstrated how important technique is. I learned a lot about GB jiu jitsu that night, but I have learned even more continuing on with my training each week. Everyone who practices jiu jitsu here is nice and friendly, they always give advice to help you learn and improve your skills.
I recommend you give this place a try. It is a great opportunity to not only get in shape, but also learn practical ways to protect yourself if a situation ever arises.
