I never walk if I can drive or catch a bus. I don't ride any more. unecessary physical exertion abhors me.
I walk about half a KM per day just inside the house. A trip to the supermarket is 200 metres from the car and back and up and down 12 aisles at about 40 metres per time adds another 500 metres. window shopping adds another half Km. If I get conned into walking the dog that's another Km. The bus stop is 300 metres away. I think I get all the exercising I need without a walking program.
Yes I am about 7 Kg overweight at 73 Kg. So what! I exercise my brain with cryptic crosswards and computer programming. This helps my brain to work out more ways of avoiding physical exertion.
Most of my athletic contemporaries have now passed on.
