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.

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?
