I registered to take a KB certification course! It isn't until June though, the classes seem to be few and far between.
It is through the International Kettlebell and fitness federation (IKFF). I did some online research and it was in the top three. I like this one best though because of its global view point. The world is a small place.
The level one certification has you master the basics and learn how to coach others. I will probably take the second certification after I complete the first one.
