I have to agree with your h about the bike. I hate the thoughts of you riding on a busy road. I just do not think it's safe. Do you have any bike paths near your home?
One afternoon I thought I would take the pup out for a walk on our road. I live in a mostly rural area and thought it would be perfectly safe....no way! The cars (even as few as the were) seemed to sneak up on us out of nowhere and then whiz by at 40 MPH. We turned around and went home. Sometimes people think that rural roads give them the license to speed.
If not a bike, then what about your h's treadmill? It's a great way to start just make sure you get the right shoes.
