W: Actually, tint'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: Yes they do. But the article I read mentioned ways to compensate for that.
M: How？
W: By adding leg exercise so the arms don't do all the work. It's said that the more of the body that's involved in the exercise, the better.
M: And in turn, I'm sure that there is a greater chance of losing weight.
W: Sounds right to me.
M: So, what exercises 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 anus and legs, and walking energetically while you wear arm weights.
M: I must try that. I like to walk a lot.
