I thought I would update, because darnit, I really want to be healthier--and if I lose weight along the way, so much the better!
Anyhow, a couple of months ago, Dave and I picked up a treadmill for $20 at one of the thrift stores, and I finally decided to break it out tonight. I walked for 16 minutes, about 3/4 of a mile, at roughly 8 mph. I worked up a decent sweat, and I plan on using it at least once a day, possibly more, but the goal is going to be to use it for a total of about half an hour a day. I'm also going to be working on eating healthier and drinking more water.
How's everyone else doing? Feeling good? Yes? Yay!
