[QUOTE="MarkB, post: 5335481, member: 40176"] As mentioned, it depends on the energy source. Someone taking an airliner from London to New York is flying a long way very fast, but they're certainly not getting much exercise during the trip, as the flight is being powered by the jet's engines. The main reason Superman makes it look effortless is that he isn't having to power that flight from his own metabolism - he's just absorbing loads of yellow sunlight as a power source, then expending it as necessary. Likewise Green Lantern doesn't need to use his own energy to fly - he gets it from his ring, which he recharges from a lantern battery. It's perfectly easy to create a character who [i]does[/i] burn calories from his own body to fuel his powers, and such a character will indeed gain healthy exercise as a result of using those powers, but it's equally easy to create a character whose energy is derived elsewhere - and if he's not expending his own energy, he's not losing weight. So the question is, which option did you use? [/QUOTE]
