Keep a good volume in your speakers and listen how fast this Russian TV presenter is pronouncing her words. I manage to get some intresting information about this video from external sources since i am not a Russian speaker. Please see blow the video for the explanation.

She hosts Vesti national news show, so what she does is a little warm up before the show starts. It’s a collection of russian tongue twisters that she pronounces surprisingly fast and clearly.

From another source :

She is pronouncing some tongue twisters or patters.
This is kind of exercise to speak fast and clear.
The text is like: There are the firewoods on the grass in the yard…
33 ships maneuvered…
The cap is sewed not like a cap…
etc etc..
