Unit 104 跑出好身材

Serious runners are renowed for their slender physiques,thanks to the hundreds of calories a good run eats up.If you're a beginner,you'll need to build up your endurance slowly.For starters,simply walk a block or two，then run a block，then walk again. Slowly increase your distance.about 10 percent a week.Three times a week over a period of several weeks，try to run longer distances and walk less. You may start out feeling like a sorry sack of potatoes，but you’ll probably be surprised at how quickly you can progress.

真的跑者皆以体态苗条著称，这都要归功于跑步可消耗好几百卡路里。如果你是个初跑者，必须先慢慢培养耐力。对初跑者而言，刚开始先走一两个街区后，再跑一个街区，然后再走。慢慢把距离加大，大约一个星期增加百分之十的距离。先试跑几个星期.每周跑三次，每次试跑远一点，走少一点。刚开始你也许觉得自已活像是一大袋可怜的马铃薯，但慢慢地你可能会很惊讶自己竟能进步得这么快。

“A runner friend of mine spent a good year hounding me to try it，”recalls Linda McCall，a 35一year--old teacher from St. Louis.“I couldn’t imagine dragging my poor body down the street，but I did want to lose 15 pounds，so a couple of years ago I finally went out one day early in the morning. I walked a half mile，then ran a block，then walked home, The next day, I ran a little farther,and the next day farther still. Before long，I was running for 30 minutes straight·which I continue to do three times a week. I'll never run a marathon,but I feel great.And I’ve lost 20 pounds一not 15!”

住在圣路易一位三十五岁名叫琳达.麦柯的老师回忆道:"我有一位跑步的朋友唠叨了整整一年叫我去跑步，我无法想象自己拖着臃肿的身躯上街跑步会是什么模样，但是我真的想减掉十五磅。所以在几年前的某个清晨，我终于开始外出运动。我先走了半英里，再跑一个街区;然后就走路回家。隔天，我跑得远一点，再接下来的一天，又跑得更远一点。不久以后，我已可以一口气跑三十分钟，且每个星期持续跑三次。我永远不可能去跑马拉松，但是我感觉很好。而亘我现在已减掉二十磅，而非十五磅!”
