Katy & Jeannette dive into the question: can movement really change your DNA? Using clear analogies—like libraries, recipes, and sticky notes—they unpack what DNA is, how gene expression works, and what we really mean by epigenetics (the “on top of” changes that influence which genes get used). They explore how exercise can turn the “volume up or down” on metabolic genes , pro-inflammatory markers , and stress protein genes , and how many of these changes involve altering the arrangement and access to DNA within your cells. Using another accessible analogy of spider webs, they explore how forces on cells (through mechanotransduction ) act as a powerful, non-chemical “nutrient” that can literally move your DNA and alter epigenetics and gene expression. This is why exercise and everyday movement not only have systemic benefits but also site-specific effects —and why the distribution of movement throughout your body matters just as much as how much you move.
