你需要鍛鍊身體的三個原因
1. It helps with addiction control
1.鍛鍊有助於控制癖嗜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.
大腦會分泌多巴胺，多巴胺會對任何形式的壓力做出反應，無論是性，毒品，酒精，還是食物。一些人逐漸對多巴胺以及產生多巴胺的物質上癮——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.
定期運動有助於你戒掉這些成癮行爲，因爲鍛鍊可以分散你的注意力，降低你對成癮行爲的渴望等級。當面對生活中的心理或者感情挑戰的時候，運動可以幫會你用健康的方式應對，而不是訴求於酒精，毒品以及其他最終只會導致你症狀更嚴重的一些其他消極的行爲。定期鍛鍊也能幫助你增強免疫系統。
2. Your risk of diabetes goes down
2.降低患糖尿病的風險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.
一週之內的定期鍛鍊之後，你對胰島素的敏感度會變得更好，這反過來會降低你的血糖水平，降低患2型糖尿病的風險。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，鍛鍊會降低你的中風風險；鑑於導致中風的兩個最大的因素就是高血壓和心臟病，運動在增強心臟功能和促進循環方面的益處非常重要。
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.
美國疾病防控中心建議，爲了身體最佳的健康狀態，每週至少5天都要適度運動至少30分鐘，但是如果你有任何健康問題的話，在你開始任何運動項目之前，你應該要常常諮詢你的醫生。3. You’re shedding belly fat
3.減少腹部脂肪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.
當你做一個月的定期運動之後，你的身體會清除那些多餘的脂肪，讓你身體的肌肉增多。一項澳大利亞的研究表明，超重的人蔘加四周的適度運動項目之後，腹部脂肪減少了12%。
