Don’t have time to hit the gym today? No worries. Believe it or not, there's a solution to missing a workout: get moving. You burn tons of calories by living an active lifestyle and eating well already. But just to prove it, we tapped into an extensive study from Harvard Medical School that measured how many calories a 185-lb guy burns during routine activities over 30 minutes.
We also used a Mayo Clinic calorie calculator for ideas of our own (like climbing the stairs to the New York City subway). The result? Our ultimate list of the 30 most surprising ways you can zap fat fast, every day—without even realizing it.
