Look you have to be who you are, if Kick Boxing is what you do, then I would be proud to mention it. There is nothing wrong with it, I put down what I like to do for hobbies on my CV or Resume. In my case its fly fishing, hunting and shooting. I'm starting a new job in a few days flying an aircraft I have never flown. Why I was hired, well he said that since I fly fish, I can't be to bad a fellow and well you hunt. It must be a 338 Winchester thing. Oh lots of Elk where I will be. The funny thing about it is I didn't expect even a phone call let alone a job offer. Just be who you are, and let the others play the PC junk.
