Use an elevator as a treadmill

There is a hall in the middle of yicaicheng, and there is a tumble between the two sides of the hall. There are not many people at a.m.

I saw a person standing on the elevator, and I thought the elevator was not open.

In the past, I was happy. He used the elevator as a treadmill.

This guy is the guy at the edge barber shop. He doesn't have much morning work, so he is exercising.

Feelings:

1. You can try your best to exercise and do not find any interfaces for yourself.

2. The elevator should be inductive. Do not run it when no one is there. You can save some electricity.
