I run every day when the weather permits. Hopefully the temperature will rise and stay about 50 here soon (yeah, I'm a wimp when it comes to cold weather), and I can start running again. I also do sit-up/push-ups on a semi-regular basis, and I occasionally do simple weight lifting stuff.

I also do a quasi martial-arts routine when I'm really motivated. It's a variety of simple punches, kicks, elbows and such, plus some defensive knife strikes as recommended by a self-defense trainer in a magazine I read. The hand to hand fighting stuff probably isn't worth much defensively, but it's an ok workout.
