I don't know too much about the R.K. Certification test other than it's both physicaly and mentaly demanding.
I'll worry about getting in some good quality time w/ my KettleBell now (Oct 08) and worry about the certifing process around Feb. 09. That will give me 5 months of carefree swinging and studying before I have to get serious.
If you or anybody you know of went through the certification I apreciate any advice you may have.
