@jk No we do not walk outside. Our rural community has no sidewalks or street lights, and we like to walk first thing in the morning. So we both use the treadmill. I walk first and then start prepping for lunch as he walks. It's helped us both. He had his first yearly heart check last week and got a good report. His cardiologist told him to keep walking. I have my endo appointment in a couple of weeks, so I hope he tells me I'm good to go too. We also walk our stairs since we live in a two story house. That is still hard for me, but I'm working at it. I made up my mind that exercise is necessary, and that's all it took. Once I make up my mind, I'm stubborn.
I hope you have a wonderful time in Denver.
