Thank you for some great and encouraging answers! I will give the dvds a try, being very careful to do things properly and with full egagement. I also found several dojo pdfs online, with detailed instructions on the kata. I know that joining a dojo is the best thing to do, however I am happy that nobody dismissed my idea to start this on my own. You just motivated me more than you know! As for the gym, I went alone, but I would have quit even with friends. I can see why you say that a dojo is not the same experience. Cardio I don't mind, as long as it doesn'r bring me to the point of a heart attack. I don't mind pushing the muscles, but the heart is another matter. As for calisthenics, I should start again I suppose, because I have convict conditioning and I love the exercises. I will simply have to be more disciplined. This forum is great, I am still reading posts. I like the focus and energy of karate more than any other thing I've tried so far. That was a very long thank you, by the way, but I mean it.
