CrossFit Journal: The Performance-Based Lifestyle Resource

CrossFit Daikanyama Instructors

Our Coaches
CrossFit also differs from your typical gym program in that all of the workouts are done in a coached environment where proper technique is highly emphasized.
Our bilingual coaches are not typical gym-style personal trainers – RCDKY coaches are not only amazing athletes in their own right but they are true professionals who are committed to helping our teammates achieve and exceed their fitness goals in a fun and supportive environment.

I started weightlifting, a hot topic among CrossFitters, at age 15. Over a long competitive career I have faced many challenges in training. I have gained knowledge about other training methods by interacting with top level athletes in other sports. I am positive that my experience will be of value to our members who are looking to grow stronger. I still have much to grow myself and look forward to growing together!

During the school days sports centered on swimming,Track&Field,karate, etc. But there were times when I was away from sports for two years in high school. I went on to a three-year trainer vocational school and acquired a sport trainer qualification. I met Crossfit and changed the way of thinking of life and fitness greatly. I am very pleased that I can be involved as a coach for crossfitting now. There are still a lot of inexperienced parts, but I will tell more people the charm of crossfit.
