孤云独去闲今天的美国，瑜伽已十分盛行，瑜伽教练和练习者随处可见。最近一项由《瑜伽月刊》委托洛普民调机构所做的调查显示，有1,100万的美国人至少会偶尔做一次瑜伽，另有600万的美国人会经常做瑜伽。瑜伽已被广泛应用于身体治疗和专业运动队的日常训练，做瑜伽的好处也被电影明星和《财富》杂志世界500强企业的总裁们争相吹捧。许多医学名校已经研究并提出能够有效缓解疾病和压力的瑜伽术了。包括加州大学洛杉矶分校在内的一些医学院甚至还为内科医学专业的学生开设了瑜伽课程。
2 There are several different schools of hatha yoga in America; the two most prevalent ones are Iyengar and Ashtanga yoga8. Iyengar yoga was founded by B.K.S. Iyengar, who is widely considered as one of the great living innovators of yoga. Iyengar yoga puts strict emphasis on form and alignment, and uses traditional hatha yoga techniques in new manners and sequences. Iyengar yoga can be good for physical therapy because it allows the use of props like straps and blocks to make it easier for some people to get into the yoga postures. Ashtanga yoga can be a more vigorous routine, using a flowing and dance-like sequence of hatha postures to generate body heat, which purifies the body through sweating and deep breathing.
2美国有许多不同的哈他(传统)瑜伽学派，其中影响最大的是艾扬格派和阿斯汤加派。艾扬格瑜伽的创立者是波·可·斯·艾扬格，他是世界上目前仍健在的最伟大的瑜伽改革者之一。艾扬格瑜伽十分注重姿势的精准，它采用新的方式和顺序练习传统瑜伽。艾扬格瑜伽有助于身体治疗，因为它允许练习者使用瑜伽伸展带、瑜伽砖等辅助器材来减少做瑜伽动作的难度。阿斯汤加瑜伽有着更精准的要求，练习者要用舞蹈般流畅的动作来练习传统瑜伽，从而使身体发热，并通过出汗和深呼吸来净化自己的身体。
3 Yoga routines can take anywhere from 20 minutes to two or more hours, with one hour being a good time investment to perform a sequence of postures and a meditation. Some yoga routines, depending on the teacher and school, can be as strenuous as the most difficult workout, and some routines merely stretch and align the body while the breath and heart rate are kept slow and steady. Yoga achieves its best results when it is practiced as a daily discipline, and yoga can be a life-long exercise routine, offering deeper and more challenging positions as a practitioner becomes more adept. The basic positions can increase a person's strength, flexibility and sense of well being almost immediately. but it can take years to perfect and deepen them, which is an appealing and stimulating aspect of yoga for many.
3做瑜伽没有场地的限制，一套瑜伽动作通常需要20分钟到两个小时或者更多的时间，而一个小时左右的时间则是一系列动作和冥想的最佳选择。根据瑜伽师和学派的不同，一些瑜伽动作做起来辛苦异常，而另一些却只是在呼吸和心跳平稳的情况下调整和伸展肢体。每天练习瑜伽会达到最好的效果，随着动作越来越熟练，你就可以加大强度和难度，这样瑜伽就能成为你相伴终生的日常锻炼方式了。练习基础的瑜伽动作即可收到增强力量，改善柔韧性并使人感到舒适的效果，但要想达到完美和高深的境界还是需要日积月累的练习，这也是瑜伽吸引人的地方之一。
