my son just spent an year and a half there... he started at 4... Its a HUUUUGE commitment... Its called z ultimate self defense studio... they have a few locations, BH, West LA... we went to the one on pico and Prosser... its expensive, about 200 a month... u make a year contract, u can always get out of it, but u do have to give 30 day notice... u have to have one private class, 30 min, and 1-3 group classes, each an hour or 45 min. long... for your kids age, the classes are on Monday and Wednesday, at 330 and i think one on sunday!!! anyway, its ALOT!!! testing costs $$$... Sparing gear, when he's reached orange and going for purple is $250!!!! anyway, for us, we've done it for a while, it became overwhelming, so we're exploring other things... if he ever wants to go back, i figured he can always do so...
u can always do a free tryout, to see if he's ready!!!
we're also gonna try another studio, its called Dawn Barnes karate kids... google it...
hope this helped...
