During my research on team sports that don't involve a ball, I discovered several unique and exciting options. Some of the most popular non-ball team sports include ice hockey, ultimate frisbee, and roller derby. These sports rely on teamwork, strategy, and physical fitness just like traditional ball sports. I was fascinated by how these sports offer a fresh and engaging approach to team-based physical activity. It's always great to learn about alternative sports that cater to different interests and skill sets!
