I find that mental movement and physical movement go hand in hand, but maybe that's just how I'm wired.
I like to keep my mind fresh by going for walks every day, by just walking around in the nature I don't only feel myself releaved physically but also mentally and emotionally. It's my "reset" button for the day.
I usually go for walks after I get home from work and early in the mornings on the weekends.
I think we are all wired that way. It might not always be possible to do both, but our wiring would like to.
Design your life so you get what you need, right?
