Kristina Willson
Personal Trainer
Kristina Willson
  • Crafty
  • Kickass leg wrestler
  • Her pet peeve is when people drag their feet (literally and figuratively)
You’ll get nothing and like it! —Caddyshack

Kristina grew up in Hillsboro, Ore, and went to college at the University of Oregon. GO DUCKS! Kristina took a sign language class at U of O and fell in love with it, moving to Seattle to enroll in an interpreter training program. She worked as an interpreter, mostly in college classrooms, for several years. She then went to the Seattle Midwifery School and worked as an interpreter while going through the program. Kristina worked as a licensed midwife for a couple of years after that and then started a family.

Sometime in her 30s she realized how powerful exercise was for her mental health. It definitely helps with her depression. And her people know that if she doesn’t get exercise regularly she becomes a cranky bitch. Kristina also believes that pregnancy is not a time to take it easy. You are training to be a parent and if you have no medical reason to avoid exercise you should keep moving or get moving.

Kristina had done kickboxing before CKO opened but it had been a few years. She became a member the month they opened. CKO is an integral part of my life now. Kristina is healthier in a different way than she’s ever been. Having used personal trainers there she became inspired to get certified. Kristina believes that in order to be healthy and active you have to find what you enjoy. If you love to kickbox, be a kickboxer. If you love cross-fit, be a cross-fitter. If you love long distance running, be a runner. Just move your body! There is room for everyone to be fit and it bums me out to hear people smack talking other people's choices of exercise.


Kristina is available for private training by appointment only. Contact her by filling out our contact form for more information.
