By Jaylaa, DePaul Healthy Trailblazer Journal | I participated in cheer, which I would recommend because it can improve strength, flexibility, and health. The pros of participating in a competitive sport are that you can earn a living from the sport and you can develop physical fitness. The cons of competitive sports are risking physical injury, [feeling] anxious, and costing a lot of money. I would recommend kids participate in a sport because it can give something to do and build your physical health.
