In 2021, in the 18 months between jobs when I was working for myself at home and having trouble getting the motivation to get out on the bike, walking was often the solution. I'd set a timer for 20 or 30 minutes and walk until the alarm told me it was time to turn back. No special clothing or shoes needed (since I almost always wear shoes that allow me to walk or stand comfortably). I found a water bottle holder that velcroed to my belt. And when I fastened it just over my right rear pants pocket it is out of the way of my swinging arms and is in a place it doesn't sway to avoid the annoyance factor.
