A trampoline is a recreational device consisting of a strong, flexible fabric stretched tightly over a steel frame with coiled springs, creating a bouncing surface. It's used for various activities, including gymnastics, acrobatics, and fitness exercises. Trampolines offer a fun way to improve cardiovascular health, coordination, and balance while reducing impact on joints compared to traditional exercise. They come in different sizes, shapes, and designs, from mini trampolines for indoor use to large outdoor models. Safety features like enclosures and padding around the frame minimize the risk of injuries. Trampolines provide both entertainment and health benefits for users of all ages.
