Kiyoko Tano Trainer

Upon her introduction to the sport, Kiyoko immediately found CrossFit exciting, not only because she could see her body shape changing before her eyes, but also due to the drastic improvements in her stamina and strength within just a few months.

Since starting CrossFit in May 2017, much about Kiyoko’s life has changed, including the decision to leave the company that she had worked for for many years.

Having moved on from her old company, Kiyoko embarked on a trip to experience training in the US — the birthplace of CrossFit — between April and May of 2018. She had to work out hard every day at six boxes (CrossFit gyms) in Hawaii and three boxes in New York, making her stronger, both mentally and physically.

Kiyoko now mainly coaches at Niseko CrossFit in Kutchan — a Japanese town renowned for its international appeal — making use of her experience and track-record overseas.
