Biomechanist Katy Bowman uses the metaphor of nutrients – and nutritious movement vs. junk food movement – to unpack what's not working for most of us about our modern lifestyle.
Turns out that even those we consider "active" spend most of their time sedentary, according to research. And our shoes, furniture, pillows and other props mean that we are not getting the full range of motion – the essential movement nutrients – out of the limited activity that we do.
This video is a decent entry point into Katy Bowman's eco-system. She's also written eight books and published piles of free content on her blog. You can even watch a video tour of her house showing the movement-hacks the family has made around their home.
Once you start thinking about movement from an ancestral point of view – what our bodies evolved to expect – you won't be able to go back to the exercise/not exercise dichotomy.
