I'm new to this site, and I'm only going to try this for a week or two (a friend suggested it), but I noticed a something here that bothered me a bit: there is no activity listing for a self-defense class. I know it must be difficult to add activities, and I can appreciate the selection you already have, but my defense class is one of the few significant physical activities that I manage to get in the week. I know it's a broad term, but assuming you do the usual (rolling, kicking, punching, getting up and down), maybe you could add some middle ground? I won't be here long, but I hear that defense classes are very popular these days, so I'm sure that others might appreciate it as well if you were to consider adding this activity. It would be a great help!
