A simple way to start moving your body more is to swap your sedentary seat for “active sitting.” How much of your body’s work are you giving to the chair? If the back of the chair disappeared, what would happen? Would you collapse backwards? If yes, then the chair-back is doing the work of your core musculature. And obviously, if the bottom of a chair dropped out we’d fall straight down because the chair is also doing the work of the legs.~ Katy Bowman from, https://www.nutritiousmovement.com/53-ways-to-take-a-seat/
