Mobility for Desk Workers: Daily Routines to Undo Sitting Damage

<p>The first two chapters of this book argue against its own title. That is the point.</p><p>Most guides about sitting repeat four claims. This one tests them, and three do not survive. Sitting is not the new smoking: 190 excess deaths per 100,000 people a year against more than 2,000 from heavy smoking. Standing is not better than sitting: a meta-analysis of objectively measured desk work found no significantly less back pain from standing (p = 0.36). And cutting sitting time did not change health: 38 minutes a day across 3,169 people, with no physical or psychological outcome improving. Even the desk fails - sit-stand desks sat 85% of the workday across two months of monitoring.</p><p>So the book is built on what does hold. The dose is two to three minutes of lower-limb movement every twenty to thirty minutes. Resistance has to be in the break, not just walking. And a ratio decided in advance beats one chosen in the moment: a fixed 30:15 schedule beat a self-selected one on pain, stress, concentration and adherence.</p><p>Inside: the Five-Move Reset, a four-minute desk break; the Hour Ledger, a twenty-minute audit of your longest unbroken block; the Four Gates, an evening protocol for hips, spine, ankles and neck; a fixed-ratio plan; a four-week installation schedule; and the red flags that mean you should stop stretching and speak to someone. Every claim carries its own limitation, printed next to it.</p><p>41 pages. Not medical advice, and not a treatment.</p>
