On a day when minds are on the big picture, let me tell you the best tiny thing I’ve started doing: standing up in the middle of the room when putting my shoes on or taking them off.
I read this tip on a physical therapy site and regret to say I can’t figure out which one, to give credit.
Especially with my pair of Hokas that has unstretchy collars and must be tied and untied every time, I get a few seconds of back relaxation and hamstring stretch reaching down to the laces, and a few seconds of balance practice standing on one foot at a time while getting the other foot in or out of the shoe.
I did say tiny thing! But it’s several times a day and takes essentially no extra time or motivation. In my current physical state (sound but sedentary) it’s working for me.
