The Exhaustion of a Hard Workout

Just finished a brutal run. Legs shaking. Lungs burning. But there's this deep satisfaction in my body that I can't describe. Not just endorphins. It's the feeling of having pushed my physical limits. Of being embodied. Of being an animal that moves through space. AI can optimize my training plan. But it will never feel the wind on skin at mile 6. Never feel the relief of stopping. Never feel muscles recovering. We are not brains in jars. We are bodies. And that matters.
