I'm nowhere near a karate school these days. I tried going back to it once, but hurt my knee from all the "sit down, get up" in the training.
I have come to the conclusion that I am too heavy and out of shape to take that part of the training right now.
As I am in school and teaching IT full-time on both counts, I am looking for an exercise routine that can be done in minimal time and anywhere to get back into shape.
I am thinking isometric exercise might be a good place to start.
