Have you ever been on a bus or in a car when it went around a corner very quickly?
If you have, you probably remember what happened. You probably felt like you were being pushed the other way.
What's happening in this picture is just the opposite. These iceskaters aren't in a bus or a car. They are making the speed themselves.
It might look like they're about to fall down, but leaning in like that is very normal when iceskaters go around a corner that fast. The harder they lean, the faster they are able to go. Number 116 is leaning so hard he has touch the ice to keep from falling over!

There were no more seats on the MRT, so I leaned against the wall and waited for someone to get up.
