这次声音又大了不少，听上去好像是有人在踏地下室的门(地下室的门是锁上的).这次又持续了三分钟左右。

This time it was much louder, it sounded like someone was kicking the basement door (which was locked). This went on for about 3 minutes.

如果你的踏车的工作时间经常超过三十分钟，那么和明显这个健身房的约束条件对你来说并不起作用。

If your treadmill workouts are usually more than 30 minutes, then the gym's restrictions obviously won't work for you.

例如，一些健身房对踏车的限制使用时间是三十分钟。

For example, some gyms limit treadmill use to 30 minutes.
