Arguably, women have to do much less to "look like a model" since that only requires not eating too many calories (facial proportions and such can not be changed anyway, require no effort), 15-minute daily skin-care routine and waxing every now and then. A bodybuilder has to alternate between bulking and fasting, pay attention to nutrition and spend many hours a week doing hard exercise to build muscle. A hollywood actor like Chris Hemsworth will not drink for two days before a topless scene to achieve that muscle definition. An emergency doctor has to be on set because it's so dangerous. And don't tell me about cosmetics or hair care... a typical football star will go to the barber three times a week minimum and they aren't even in close-up shots.
