There have always been a lot of commonly believed but false(虚假的) ideas about being fat and doing exercise. Some people believe that they can't help putting an weight as they get older, while others hold that if they stop exercising, their muscles(肌肉) will turn into fat. Here are some more myths.
I’ll never lose weight--I come from a fat family
Wrong! While we can't change the body type we are born with, we can't blame our genes(基因) for making us fat. There's plenty of evidence that fatness runs in families, and the main reason is that they share the same habit of eating too much and exercise too little.
I am fat because I burn calories slowly
Wrong! Fatness is not caused by a slow metabolism(新陈代谢). In fact, although fat people consume(消耗)  more energy than slim people, they also fail to realize how much they eat. Keeping a diary can help you work out your daily food intake more accurately(精确地).
Exercise is boring
Wrong! Anything will become boring if you do it again and again. The key is to develop a balanced and varied(各种的) program that's fun as well as progressive(不断进步的). If you enjoy a Sunday walk, take a different mute. If you do yoga(瑜伽), try a tai chi class.
No pain, no gain
Wrong! Exercise is not meant to hurt. Indeed, pain is your body telling you something's wrong, and continuing to exercise could lead to serious injury(伤害). You may experience mild discomfort as you begin to exercise regularly, but this is your body adapting to the positive changes in your lifestyle and the aches should disappear quickly. If they don't, rest and ask for medical advice.
