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: Ann exercises? Is that because our arms are too fat and lacking energy?
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.
