Well, if you live in a decent sized city, and have a bit of extra cash, and you seem to like swords, you should sign up for a fencing class. That's what I ended up doing trying to figure out a way to get exercise and have fun. I'm not just talking about foil fencing. I take Kumdo twice a week. It's Korean swordfighting, a bit like Japanese Kendo (actually it's descended from it. When Japan took over during WWII, they forced Koreans to learn it. When Japan got kicked out, the Koreans basically said the hell with you, we'll take this and do our own thing with it). It's crazy fun. It gets me away from the house, so no distractions, and it's fun dueling other folks in fights. There's some upfront costs, of course, but it's worth it in my opinion. I pay $59 a month for a 6 month membership, and it costs about $50 initially two buy the two swords you use, the recognizable bamboo one, and a wood sword for practicing forms, plus another $50 for the uniform.
It makes a BIG difference. I lost 30 pounds in 6 months, I could run a good mile without getting too winded where I used to be lucky if I could do 300 yards, and my reaction time's gotten a lot faster. I turned out to be really good at fencing, too. Managed to beat a 2nd degree black belt (who was the main instructor at a school in a different town!) in the second round of a tourney, and forced him into a sudden death match in the final round (double elimination tourney. He worked his way back up through the loser's bracket). I ended up losing, but damn it was epic.
You can check around your area and see if its available. Most places will let you try out a single day for free, and most will let you use the school's swords and sweats up until you finish white belt and finish the test for yellow.
