Hi, my name is Angelina Zdorovytska. Right now we're in the beautiful city of Los Angeles in Beverly Hills. I started playing tennis when I was 7 years old. I was ranked number 1 tennis player in the Ukraine. 350 in the world ranking. I run my own business; it's besttennisever.com. I train very good players. Also, I train beginners, intermediate players. Tennis is my life and my passion. I live for it and now I would like to talk to you about tennis. I'd like to tell you about the layout on a tennis court and different lines and how we call them in tennis. We have a baseline, this is the baseline right here, we have a service line. This is the service line, we have the T and we have the alley. You have the singles court and the singles court is when you play singles and it is not including the alleys. And we're using the alleys when we're play doubles. You can position yourself anywhere in a court when you play tennis, but please don't go to the other side, on the opposite side of the net.
