There's a study going around: researchers had adults with mobility-affecting conditions try a seated exercise program for 12 weeks, one group in a live online class, another doing the exact same exercises alone from pre-recorded videos.
The heart-health numbers barely changed either way. What did change was how many people actually kept doing it. The live group stuck with it noticeably more than the video-only group, even though the workouts themselves were basically identical.
So maybe the exercises matter less than we think, and the structure around them matters more, a set time, someone who'd notice if you didn't show up. Not everyone has that ready-made.
If you don't, this week could be about building one small piece of it yourself: a timer on your phone, a note where you'll see it, telling one person what you're trying so they ask how it went.
What's the one thing you'll set up this week?
Here is the link to the study if you want to read more.
