I haven't had a lot of opportunities to "do" Tang Soo Do as of late. In fact, the last 2 years have been a rather painful transition from lining up in class and occasionally teaching, to being in front of the class and doing most of the teaching. In a 2 hour class, I may do roughly 5 minutes of demonstration.
For me class has become less doing, and more teaching. As things progress, I even teach less and oversee others teaching even more. In some ways, I almost feel superfluous to the whole thing. In some ways, that's a good thing as it means I have great faith in my other instructors and senior students.
So now I find myself wrestling with the same problem as many of my teaching colleagues. Where and when do I find the time to train for myself?
How much time do I need? If it is my primary form of exercise, quite a bit. If I'm just working on recall and refining my current skillset, not nearly as much time is needed.
