閱讀下面的出自一個關于鍛煉的網站的文章。
Aerobics is one of the most beneficial and also one of the most beautiful forms of exercise.
有氧運動是最有益也是最漂亮的運動形式之一。
Any physical activity that makes your pulse get quicker and your breathing get deeper is a kind of aerobic exercise.
任何一種能讓你的脈搏更快，呼吸更深的體育活動都是一種有氧運動。
The word 'aerobic' means 'with oxygen' or 'having oxygen'.
“aerobic”意思是“需氧”或“增氧”。
Aerobic exercise therefore aims at making the heart and lungs work at a higher rate so as to supply more oxygen to the muscles.
所以，有氧運動就是讓心臟和肺部更快速地運作，給肌肉提供更多的氧氣。
The benefits of aerobic exercise include having a strong heart, lower blood pressure, stronger bones, better sleep, less body fat, more energy and less stress.
做有氧運動的益處包括強健心臟，降血壓，強健骨骼，提高睡眠質量，減少體脂肪，增強活力并減小壓力。
It is suggested that you do aerobic exercise for twenty to forty minutes, three to four times a week.
建議你每周做三到四次的有氧運動，每次做二十到四十分鐘。
Only then will you begin to reach your optimal level of general fitness.
只有這樣你才能開始達到最理想的全面健康的水平。
When you exercise, the speed at which your heart beats, or your pulse rate, tells you how intense your workout is.
當你鍛煉的時候，你心跳的速度或脈搏的快慢會反映出你訓練的強度。
People who are not fit but want to lose weight should keep their pulse rates low and do moderate exercise for a longer time.
身體不太健康但是想要減肥的人應該保持較慢的脈搏并且做更長時間的，強度適中的鍛煉。
People who are quite fit can do exercises that require large amounts of energy. They can even compete in marathons.
身體十分健康的人可以做一些需要大量體能的鍛煉。他們甚至可以參加馬拉松賽跑。
