That's definitely an important point to be mindful of.
I was also attempting to target those of us who simply enjoy the process and outcomes of a walk, and don't get the same benefits from running or jogging. When I run or jog, which is rare because I detest it (but love spending serious time lifting and training other ways), I'm always focused on my
body, on pushing myself, on my breathing, etc.
When I walk, I can go forever and forget about my body. I get lost in thinking, reflecting, processing, etc. Walking is pure joy. Sure, it has positive physical effects. But I particularly seek the peace of mind that comes from going on walks. It's something I enjoy so much, I often pick my travel destinations based on how much walking I can do while exploring a new place. Walking has long been almost like meditation for me.
By trying to walk a certain number of calories daily, you might be healthier.
