As CKD black belts we all need to train, and training in your own school is great, but sometimes training with students and instructors outside of your school is even better.
1. Different students train differently. This forces you to step outside of your comfort zone.
2. Different instructors teach differently. There's a high chance that you'll learn something new, or look at something you already know in a new way.
3. It's fun! Think of it as a reminder that we are all part of the Choi Kwang-Do family.
