A combat sports centre in Moscow, Russia, invited those feeling vulnerable to learn some new selfie stick defence techniques.

As the trainer pointed out, you do not always have a tool at hand, and not everyone can use force in martial arts. Moreover, he thinks that the tool people normally use for taking pictures is very effective.

One customer said that she decided to come to the combat class because it was very exciting and because she thinks that it is necessary to know how to protect yourself in a difficult situation.

Difficult words: combat (related to fighting), vulnerable (in danger).
