I found that now that I'm wearing a pedomiter I tend to get up and even move more around the house.
Some don't work well because they count everything; even in a car ride it would rack up numbers. I bought one online by Omron and it lets you look back 7 days.
If my health issues flair up, I will go around the park with him. Then sit a lap out, then walk with him, then sit a lap out.
We found a few places to walk outside where we can do that. I got sick this summer and had a foot injury so I'm starting over in the past few weeks. Hope that helps
