Chapter 15 — Fitness & Exercise
Is running bad for my knees?
No — long-term runners have lower rates of knee arthritis than sedentary people. What causes injury is doing too much too fast. Follow the 10% rule: don't increase weekly distance by more than 10%.
Follow-up questions
How to start running?
Walk-run intervals (Couch to 5K). Softer surfaces, decent shoes replaced every 500–800 km, and build gradually.
Barefoot or cushioned shoes?
Individual — no universal winner. Match to your body, distance, and terrain.
