A youth bouncing on a trampoline. A trampoline is a device consisting of a piece of taut, strong fabric stretched over a steel frame using many coiled springs. People bounce on trampolines for recreational and competitive purposes.
The repetitive bouncing motion of trampolining actually has many health benefits that make it appropriate for people of all ages and almost all health statuses. The trick to getting the most out of a trampoline is choosing â and using â a trampoline thatâs most appropriate for your needs and living situation. Consider the health benefits of trampolining as well as your goals, budget, and space to find (and get inspired to use) the right one.
