你需要锻炼身体的三个原因
1. It helps with addiction control
1.锻炼有助于控制癖嗜The brain releases dopamine, which responds to any form of pleasure, be it sex, drugs, alcohol or food. Some people become addicted to dopamine and substances that produce it—especially drugs or alcohol.
大脑会分泌多巴胺，多巴胺会对任何形式的压力做出反应，无论是性，毒品，酒精，还是食物。一些人逐渐对多巴胺以及产生多巴胺的物质上瘾——尤其是毒品或者酒精。Regular exercise can help in this addiction recovery as it effectively distracts you, making you de-prioritize your cravings. When faced with mental or emotional challenges in life, exercise can help you cope in a healthy way instead of resorting to alcohol, drugs or other negative behaviors that ultimately only make your symptoms worse. Regular exercise can also help to boost your immune system.
定期运动有助于你戒掉这些成瘾行为，因为锻炼可以分散你的注意力，降低你对成瘾行为的渴望等级。当面对生活中的心理或者感情挑战的时候，运动可以帮会你用健康的方式应对，而不是诉求于酒精，毒品以及其他最终只会导致你症状更严重的一些其他消极的行为。定期锻炼也能帮助你增强免疫系统。
2. Your risk of diabetes goes down
2.降低患糖尿病的风险Within one week of your regular exercise, your sensitivity to insulin becomes greater and that, in turn, lowers your blood sugar levels, reducing your risk of Type 2 diabetes.
一周之内的定期锻炼之后，你对胰岛素的敏感度会变得更好，这反过来会降低你的血糖水平，降低患2型糖尿病的风险。Also, exercise can decrease your stroke risk; given that two of the greatest risk factors for strokes are high blood pressure and heart disease, exercise with its benefits of a stronger heart and better circulation is crucial.
而且，锻炼会降低你的中风风险；鉴于导致中风的两个最大的因素就是高血压和心脏病，运动在增强心脏功能和促进循环方面的益处非常重要。
The U.S. Centers for Disease Control and Prevention recommends at least 30 minutes of moderate exercise at least five days a week for optimum health, though you should always check with your doctor if you have any health concerns before beginning any exercise program.
美国疾病防控中心建议，为了身体最佳的健康状态，每周至少5天都要适度运动至少30分钟，但是如果你有任何健康问题的话，在你开始任何运动项目之前，你应该要常常咨询你的医生。3. You’re shedding belly fat
3.减少腹部脂肪When you do one month of regular exercise, your body ditches those excess fats and gains muscle. An Australian study shows that overweight people who took part in a four-week program of moderate exercise reduced abdominal fat by 12 percent.
当你做一个月的定期运动之后，你的身体会清除那些多余的脂肪，让你身体的肌肉增多。一项澳大利亚的研究表明，超重的人参加四周的适度运动项目之后，腹部脂肪减少了12%。
