     For a while, my neighbourhood was taken over by an army of joggers(慢跑者 ) . They  were  there  

all  the  time : early  mornings, noons,and evenings. There were little old ladies in gray sweats, young

couples in Adidas shoes, middle-aged men with red faces. "Come on !" My friend Alex encouraged me

to join him as he jogged by my house every evening. " You'll feel great. "

      Well,  I had nothing against feeling great and if Alex could jog every day, anyone could. So I took up

jogging seriously and gave it a good two months of my life, and not a day more. Based on my experience,

jogging is the most overvalued form of exercise around, and judging from the number of the people who

left our neighbourhood jogging army,l'm not alone in my opinion.

      First of all ,jogging is very hard on the body. Your legs and feet take a  real pounding (重击) running  down  a  road  for  two  or  three miles. I developed foot,leg, and back problems. Then I read about a

nationally famous jogger who died of a heart attack while jogging,

and I had something else to worry about. Jogging doesn't kill hundreds of people, but if you have any

physical weaknesses,jogging will surely bring them out , as they did with me.

     Secondly,  I got no enjoyment out of jogging. Putting one foot in front of the other for forty-five minutes

isn' t my idea of fun. Jogging is also a lonely pastime. Some joggers say, " I love being out there with just

my thoughts. " Well, my thoughts began to bore me, and

most of them were on how much my legs hurt.

      And how could I enjoy something that brought me pain? And that wasn't just the first week : it was

practically every day for two months. I never got past the pain level, and pain isn't fun. What a cruel  way 

 to  do  it !  So  many  other exercises , including  walking , lead

to almost the same results painlessly , so why jog?

       I don't jog any more , and  I  don't think  I  ever will. I'm walking two miles three times a week at a

fast pace, and that feels good. I bicycle to work when the weather is good. I'm getting exercise, and I'm

enjoying it at the same time. I could never say the same for jogging,and I've found a lot of better ways to

stay in shape.
