Hi, I try to add more steps in my day. I keep track with a Fitbit but there are cheaper alternatives out there that work fine. I have mobility issues because of osteoarthritis in my knees, hips, feet, spine etc. Before surgery I would use a scooter to do grocery shopping. Sometimes now I do it without a scooter on days that my pain isn't as bad. I have started bowling with small balls (duckpin) which is ok most days and increases my daily steps. Sometimes I do small isometric exercises while sitting in the car, like tensing my stomach muscles for a count of 5 and releasing, and repeating.
I used to sit on a stool when getting laundry out of the washer and hanging it to dry in the washroom. Now I sometimes stand instead while doing it.
