rotating weight is way different than sprung weight. the weight in his gut is not as important as every little ounce he gets off his spinning wheels.
notice, for instance, not only is it "heavy" in terms of gravity, but it also has mass in terms of centrifugal weight, (can i say that?), that is to say, that every time it goes up and down it takes work, it takes work to lift a stud against gravity.
