(Disclaimer: Because I am dealing with MS fatigue and stiffness, this "workout" has a higher level of difficulty for me than for someone who does not have MS - they will have to adjust as needed.)
Stretching and Bending - Get up and feed the cats first thing in the morning. Repeat throughout the day as often as cats wish to eat. One cat has hyperthyroidism and eats about ten times per day. Summer additions - picking up trash in yard and pulling weeds.
Climbing - One word - stairs.
Walking - For the summer, I've added dragging the hose around the yard to water the flowers, and walking to the door to let the cats in and out of the house as often as they wish to this part of my routine.
Walk around house to clean, walk in parking lot of doctor's office, grocery or other store, etc. (distance varies depending on whether or not handicapped parking spot can be obtained), walk through store pushing shopping cart. Occasional walking in yard or at the park. Every step is a journey! (Tee hee.)
Weightlifting - Carry grocery bags into house (usually divided into stuff that needs to come inside right away and stuff I can leave in the car and get later), clean cat litter box (as in dump out old clay litter and replace with fresh), carry cat litter bag or laundry basket up and down basement stairs (combines lifting with climbing), drag heavy trash cans to curb (combines lifting and walking).
Cardio - Um, no. Unless the seasonal tasks like leaf raking and snow shoveling count.
I don't know how many calories I burn with my workout routine, but I can say that at the end of the day, I am wiped out!
