🏃 What happens to your body in the first 10 minutes of a run:
Most people quit at minute 3. That's exactly the wrong time to stop.
Here's what's actually happening:
→ 0–2 min: Lungs demand more oxygen than they have. It feels awful. This is normal.
→ 2–4 min: Heart rate climbs. CO2 builds up. Breathing feels impossible.
→ 4–6 min: Blood flow redistributes. Muscles get warm. It starts to ease.
→ 6–8 min: Endorphins start releasing. Breathing syncs. You find a rhythm.
→ 8–10 min: The runner's shift happens. You could go for an hour.
The pain you feel at minute 2 is not unfitness.
It's your cardiovascular system switching fuel sources.
Push past 7 minutes.
Every single time.
That's where fitness actually begins.
