A trampoline is a device consisting of a strong fabric surface stretched over a frame using springs. It is designed for jumping and bouncing, providing a fun way to exercise and improve coordination. Trampolines come in various sizes, from small ones for children to larger ones for competitive use. Trampolines are often used in recreational settings, such as backyards and parks, as well as in professional sports like gymnastics and diving. Safety features, such as nets and padding, are commonly added to reduce the risk of injury while using a trampoline.
