要是你真的喜欢一开始跑就进入节奏的话，在跑步或上跑步机前先热热身吧。

If you really like to get right into your groove when you start running, warm up before you head out from your run or jump on the treadmill.

开始你的有氧锻炼吧。每周至少做三次，花15分钟热身，20分钟做有氧运动，然后再用15分钟的时间让身体放松平静下来。

Start out with at least three sessions a week, with 15 minutes of warm-up, 20 minutes at your aerobic training zone, and 15 minutes of cool-down.
