Playing sports is so important when you're young, especially for girls. Being on a team or training for an individual sport like tennis or track helps to build friendships, teaches you how to communicate and work with others, and builds confidence, and it's a great way to encourage kids to get in the habit of staying active. When I was a kid, soccer was my sport, but I'd play just about anything. So what about you? Did you play sports as a kid? If so, tell me: What sports were you involved in?
