I want to echo your advice. I recently started playing a combat sport after a few years of not really exercising. I have no illusions about its likely effectiveness in a real fight (not much), but since I don't plan on getting in a real fight that doesn't matter. It is fun and interesting compared to other forms of exercise I've tried, and it definitely helps me get my cardio up. There are a couple other benefits too: when you are paying $150 a month for the class sessions, you show up. And it's easier to keep going with an instructor there pushing you than by yourself. There's also no team depending on you to be good, so there's not the same kind of pressure to perform. For someone like me whose self-control and discipline are perhaps below average, these benefits are no small issue. I didn't start doing this to be a better worker; my primary motivation was vanity. But anecdotally, I have noticed that my productivity level has been somewhat elevated in the month since I started doing it. I'm not sure if it's the fact that I have to leave work at exactly six PM every day, giving me a solid deadline for whatever I want to accomplish in a day, or if it's the exercise itself. Heck, it could be a mix. But as far as I've seen so far I would definitely recommend it.
