I have been going to Berkeley Isshinryu for over seven years now, so I figured I should finally…read morewrite a review! Because you don't do something for seven years if you don't love it.
BIK is a small, laid-back dojo made up of a diverse group of practitioners from many different Isshin-ryu "strands" and in some cases completely different styles of karate or other martial arts altogether -- everyone is welcome here, and over the years the dojo has benefited from getting lots of different perspectives on the style and martial arts in general. We work hard and take our training seriously, but everyone is primarily there to have fun while also learning martial arts & staying in shape. Many of us also hang out & socialize outside of class as well, and there are regularly post-class pizza & beer trips for birthdays, promotions, etc.
Because of the small size of the class, everyone gets plenty of attention, both as part of the group and during individual work time. The instructors are positive and friendly, and provide helpful and constructive feedback in an encouraging way. Again, although we work hard, this is not a super-aggressive, testosterone-driven dojo, so beginners or people who are less excited about the combat aspect of martial arts don't usually end up feeling intimidated or uncomfortable (and people who *are* looking for a super-agro school don't tend to stick around for long).
We usually start with 10-15 minutes of stretches & light calisthenics, then spend the rest of class on some combination of basic techniques, kata study, pad work, partner work, self-defense, or sparring. (Students begin sparring only when the instructors think they are ready, and with plenty of supervision; also, no one is ever required to spar -- or do anything else, really -- if they don't want to.) The intensity of the workout is more or less self-selecting; if you want to be sweaty & panting by the end, there are usually opportunities to work hard enough to make that happen. If you want an easier, gentler workout, you can always dial it back to whatever you're comfortable with & ready for.
Highly recommend! Again, I wouldn't still be here after seven years if I didn't think both the class and the people were awesome. :)
