I'm in love with ILKB Yorba Linda! It's an over-all body workout that's fun. I had never done anything like it before, but I wasn't intimidated at all when I went to my first class. You get great one-on-one time with the coaches so you learn proper form and technique to punch the heck out of the bag! (It's actually kind of therapeutic!) I go to the early morning classes and the coaches always get me motivated to work hard. I definitely leave there ready to take on the day.
