Yes I do that optinum number of steps at least, even if indoors all day, I am always moving around and up and down stairs too. I dont actually aim for a set number of steps, it just happens
Most days I add a short walk of around 30 minutes. It is so important to keep moving and lifting. I am 78 and still walk upright and have working muscles. I am no exercise lover, the exercise just happens and works with or because of, my healthy anti-inflammatory eating,
Two or three times a week I do incorporate a steep hill in my walk, enough to make me puffed, recovery is good, which makes me happy
I know about the number of steps I do, now I bought myself a garmin vivoactive last month
It is all about getting old healthily and being able to continue with summer cycling and my allotment and keeping my inner vital force in a good active state. So I can enjoy my life
