I used to do kickboxing when I was young had to give that up as well for moving home, I've been doing Iaido for about 3 years now so has the wife, she was complaining how she never saw me on nights so I dragged her along and she loves it
Kendo I've been on and off for three years as well mostly due to injuries in my legs but I think I am fit enough now to take it back up, basically my inner thigh muscles stopped working but I have that sorted now
and I am fitter than ever
http://www.budokan-dojo.co.uk/newspage.html this has an account of the summer seminar weekend as told by our friends at Budokan Dojo in durham (the crazy lot lol) if you scroll down to the picture under the text "Last day, grading day." you'll see me in the back bowing at the start of my grading (the one with the crappy beard lol!). It was fun my back is still killing me though shows I am still doing it wrong
