Hi, Rick. The best place to start might be with including your full name in your signature; it is one of the forum rules and you will find more people willing to help you if you do so. If you don't, the moderators might ban you from the forum. If you look at the top of the page you will see the User CP option. If you press that and choose to edit your signature, you can arrange to have your full name automatically added to each post.
With regards to your question, I'm not exactly an expert, but the best advice that I can give you is to find out what martial arts are available in your area. I think that there quite a few reputable sword options in the state of Washington. You should probably check them out and try to see first-hand if these classes will fit in with your interests and physical abilities. Also, talk to the instructors and see what they think you should do. The instructors might be able to offer you some really good advice on what type of conditioning would be best for their class, and if you meet them face-to-face they'll be able to form a better opinion of what's best for you than a bunch of people on the internet.
Best,
David Sims

My opinion is, in all likelihood, worth exactly what you are paying for it.
