I hear you on the deductibles! Milk that free healthcare as much as possible. Yoga is fantastic. At least, it should be. Not tremendously easy to do when you are larger (despite what those "Plus Size Yoga!" books claim. I want to pursue that after surgery, it's supposed to be great for your mind and body.
I also plan to get a personal trainer, dependent upon whether I can find one that doesn't charge a small fortune. I don't think I will need them too long, just a few months to tell me how to do things, which exercises to focus certain areas etc. I haven't seriously worked out in over a decade, and I highly doubt the exercises I did then as an athlete would be the best idea now. I also have a nice expensive elliptical I hope to actually be able to use. I purchased it at my highest weight, then swiftly realized that if I used it for me than 10/15 minutes my knee would swell to the point I couldn't walk. Yeah... my knees haven't taken this whole being 280+lbs thing very well.
The thing that I am looking forward to exercise wise is to be able to go for a run. I used to love it. Hopefully, I'll get back to doing morning runs every day.
