Walking and other ways of exercising

I've been walking up and down my hall every day, since it's been either too cold or too rainy to walk around the neighborhood.  Since I usually do it late in the evening, I'm the only one in my hallway.  So I've been adding a few things, like shrugging my shoulders up and down as I walk (which would look pretty strange if I were passing others along the way).  I have added moves like that one on the right, with my forearms up and pressing inward and back to the side as I walk along.  In other words, I'm trying to move various parts of my body while also getting in something like 5,000 steps a day, or more if possible.  I could go to the weekly 30-45 minute group that exercises together while sitting in chairs.  Or I could try to get in more of those moves in the drawings above.  Today, I found this drawing of exercising in a chair that I had used in a blog post back in 2020 and decided to put it here so I'd remember it.
