Don't have any riding-specific suggestions (I could use a few of those myself), but a couple for general fitness.
Try biking, especially if you have to go to work/school every day. (And it's a reasonable ride, of course.) I find it's really good if you get one of the bike computers that keeps track of speed, distance, trip time, and so on, 'cause I'm usually pushing myself to beat my records. And when I figured time spent at traffic lights, parking, and so on, biking wasn't that much slower than a car.
Another thing is to make little opportunities for exercise as you go about your day. Climb stairs instead of taking the elevator, park in the first spot instead of circling to find one close to the store, when you walk someplace, walk fast...
