Share Your GRIT.

We want to make the world vivid with the power of sports by giving back to the world the craftsmanship that has evolved the performance of top athletes and by building a wellness community that "enjoys evolution".


Gym studio to train movements


This studio is where you can experience GRIT Performance Architecture. By "training movements" instead of muscles, we bring back suppleness to modern people who have become accustomed to convenience. Coaches with diverse backgrounds as athletes, trainers, and healers will accompany people at every stage of their evolution.


Nutrition and rest suggestions to support high performance


What to eat, how to rest. Being prepared on a daily basis is another important factor that leads to high performance. We are engaged in research and development of products that enable people to move as they wish.


Consulting and team support based on GPA


One's greatest joys are given by others, and it is also relationships that trouble people the most. GPA is used to foster a community where people recognize each other's value, and enhance each other's skills, much like a sports team.
