It is designed for jumping and bouncing, providing a fun way to exercise and improve coordination. Trampolines come in various sizes and shapes, often used in backyards, gyms, and competitive sports. Trampolining is also a sport where athletes perform acrobatic moves while bouncing on a trampoline. It is included in events like the Summer Olympics, showcasing skills such as flips and twists. Safety measures, like nets and padding, are important to prevent injuries during use.
