Violet: Doctor, I took your advice and bought a stationary bike amonth ago. However, I really regret that I bought the bike.
James: Really? What happened? Could you tell me in detail?
Violet: I weigh myself every day and I haven’t lost a pound. In fact, I have put on a few pounds.
James: I suggest that you should ignore the scale. When you exercise, your bones become denser. In other words, you are getting stronger.
Violet: So I didn’t get fatter?
James: You are right. You just got healthier.
Violet: OK. But I don’t think I’m losing weight quickly.
James: Well, how often do you use your stationary bike?
Violet: When I have time. I usually use it on weekends.
James: There you go. That’s not enough. In general, you should use it at least 3 times a week.
Violet: Now I got the point. Thanks, doctor.
James: You are welcome. Good luck.
