I decided to try ILKB with my aunt and cousin because they just raved about it and I needed to get it into gear but didn't have the motivation. My very first class I was taught proper form and "how to" do different punches/kicks combos etc. (my instructor was Tommy, he's awesome and very patient). Once you know what you're doing the instructors are so motivating and helpful.
I don't know what to do when I go to a regular gym, but this class kicks my butt.
I purchased a membership where I get a certain amount of classes that never expire.
There is a monthly unlimited membership as well.
