My wife and I are reading this book called &quot;Move Your DNA&quot; (by Katy Bowman). She has an interesting thesis: modern exercise is &quot;junk movement&quot; (like &quot;junk&quot; food). The idea is that humans were meant to move more throughout the day, and that trying to cram all of our needed movement into a small 45-minute block is similar to how junk food crams tons of calories into a small bit of food.<p>We&#x27;re not finished with it yet, but initially, I find it interesting.
