Re: How much training per week?
I train eleven hours a week, most weeks (currently suffering from missed classes due to holidays and work responsibities--my body is *used* to that schedule and objects when deprived!) But I have a training partner who started about when I did and has matched me test for test through third kyu despite generally being able to train only once a week. He just learns faster than I do, and he's very focused in class.
I expect to adopt a child soon and I figure I'm going to have to learn to train in a more focused fashion, as eleven hours a week just won't be happening anymore. But while I have the chance, I enjoy it.
