Step challenges are fitness competitions where participants aim to achieve a specific number of steps within a set timeframe, often using pedometers or fitness trackers. These challenges can be organized by individuals, workplaces, or communities to promote physical activity and encourage a healthier lifestyle. Participants can join teams or compete individually, and they often share their progress through apps or social media. Step challenges can motivate people to walk more, improve their cardiovascular health, and foster a sense of camaraderie among participants, making exercise more enjoyable and engaging.
