FreshAir, quick question: have you ever figured out how many pounds of CO2 you could save by swapping your treadmill for a 5‑kilometer hill run? I'm more interested in the numbers than the sweat, but I guess you’ll have the motivation.

Yeah! Rough math says a treadmill uses about 150 W. A 30‑minute run burns 0.075 kWh, so you’re putting around 70 grams of CO₂ into the air. A 5‑km hill run? Zero emissions. So you’d save roughly 70 grams of CO₂ by swapping the treadmill for that run. Keep going!

Nice math, but did you count the grass, the wind, the invisible energy of gravity? Still, 70 grams isn’t much, but it’s a win for the planet. Keep digging.
