Warming up?

If you watch a game of football, you would have noticed there are players warming up at the sidelines next to the pitch. Most of the time, these players are either jogging along the sidelines or doing some stretching exercises.

Next time if you happen to see football on tv, then remember this post. Watch the players carefully at the sidelines presumely stretching their legs.

You might see something else. They are not really stretching but doing this....
