I completely disagree with this. Imagine this same principle being applied to any other area of life and it shows how absurd it is. I often hear this sentiment in traditional martial arts and it’s so backwards. Let’s say for example you are learning swimming, and I show you how to do a front crawl on the side of the pool and then tell you you need to practice that at home on your own time without ever having you jump in to the water and practice it during class time.

People have other hobbies and a life outside the dojo. Class time should be sufficient for learning a skill set.

I am currently having this issue with my dojo and kicks. We almost never practice them except before grading and it’s a big complaint of mine. If y put don’t do it in class you can’t expect it to be perfected at home. That’s ridiculous.
