Aerobics is one of the most beneficial and also one of the most beautiful forms of exercise.
有氧运动是最有益也是最漂亮的运动形式之一。
Any physical activity that makes your pulse get quicker and your breathing get deeper is a kind of aerobic exercise.
任何一种能让你的脉搏更快，呼吸更深的体育活动都是一种有氧运动。
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，有氧运动就是让心脏和肺部更快速地运作，给肌肉提供更多的氧气。
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.
做有氧运动的益处包括强健心脏，降血压，强健骨骼，提高睡眠质量，减少体脂肪，增强活力并减小压力。
It is suggested that you do aerobic exercise for twenty to forty minutes, three to four times a week.
建议你每周做三到四次的有氧运动，每次做二十到四十分钟。
Only then will you begin to reach your optimal level of general fitness.
只有这样你才能开始达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.
当你锻炼的时候，你心跳的速度或脉搏的快慢会反映出你训练的强度。
People who are not fit but want to lose weight should keep their pulse rates low and do moderate exercise for a longer time.
身体不太健康但是想要减肥的人应该保持较慢的脉搏并且做更长时间的，强度适中的锻炼。
People who are quite fit can do exercises that require large amounts of energy. They can even compete in marathons.
身体十分健康的人可以做一些需要大量体能的锻炼。他们甚至可以参加马拉松赛跑。
