Dear Andrew,

It's great to hear that you are looking to take up a sport to get fitter and feel better! Both basketball and tennis are fantastic choices, so you can't go wrong with either one. As for popular sports among teenagers in Russia, some of the most popular ones include football, ice hockey, volleyball, and gymnastics. Many teenagers also enjoy skiing and snowboarding in the winter.

In terms of sports facilities at my school, we have a gymnasium with basketball hoops, volleyball nets, and mats for gymnastics. We also have a football field and a track for running and field events. Additionally, we have a swimming pool for swimming and water sports.

At my school, we have various sports competitions and tournaments throughout the year. We have interclass competitions in football, basketball, and volleyball, as well as track and field events. We also compete against other schools in regional competitions.

I hope this gives you some insight into sports in Russia. Let me know if you have any more questions or if you need any advice on choosing a sport.

Take care,

[Your Name]
