听力原文：W: Exercise, exercise, exercise! We hear so much about it these days. Yet even the experts can't agree on which exercises are best. Now some doctors are strongly encouraging arm exercises.
M: Arm exercises？ Is that because our arms are too fat？
W: Actually, that's not the main reason. They say that arm exercises are an ideal way to become physically fit.
M: But don't arm exercises raise your blood pressure？
W: That they do. But the article I read mentioned ways to compensate for that.
M: How？
W: By adding leg exercises, so that the arms don't do all the work. Arm exercises alone aren't enough to increase metabolism before fatigue sets in. The more the body is involved in the exercise, the better.
M: And in turn I am sure there's a greater chance of losing weight.
W: Sounds right to me.
M: So what exercise do the experts recommend？
W: They mentioned quite a few. But some of the more popular ones are cycling with special bicycles that make you use both your arms and legs, and walking vigorously while you wear arm weights. And the key words to keep fit are "keep exercising".
M: I must try that. I like to walk a lot. There is no way to lose weight without exercises, anyway.
