We are taking Shotokhan karate at the Foothills Aquatic Center. It's $15 a month for Glendale residents, $18 a month for non-residents. The youth classes are from 7 - 8 Tuesday and Thursday, the adult classes are 8 - 9 Tuesday and Thursday.
Great sensei, plus John Harmon, the brown belt instructor, goes to our church as well and is a great guy. Ivan has really taken to the focus and discipline of martial arts and after him doing it for a couple month, I too joined. I love it. It's great exercise, cool as heck, and if you are in the adult class, they encourage you to participate in the youth class at no charge, so Ivan and I get to do it together for an hour, then he sits in on my class (in fact, last week, Sensei had him act as my instructor as I was not getting a certain block that he had mastered! LOL Ivan loved it, Dad, not so much...)
ANYWAY, it's cost effective, tons of fun, and I can now kill people with my little finger... for $15 a MONTH. You don't need the little karate outfit, but if you stick with it, you'll want to order one. Ivan's was $25 with shipping.
PM me if you want the link or your want to come and observe first. I'm in Santa Barbara tonight, tomorrow, and all day Wednesday, so I won't be back in class until Thursday.
