The D Stance

In many sports, there is a specific "defensive stance" that players learn. In some of the sports that I've played, they look like this:

Basketball (not me)

Football (I can't remember if this is me)

Lacrosse (also not me) 

Well, recently I saw that China has a bus especially for people doing these "D-stances." The only requirement seems to be that you can hold your stance for a long time.

One day I'll ride you, Long D stance Bus. When my endurance is a little better.
