Trampolining is a competitive sport in which gymnasts perform acrobatics while bouncing on a trampoline. These can include simple jumps in the pike, tuck or straddle position to more complex combinations of forward or backward somersaults and twists.

There are two related competitive rebound sports: synchronised trampoline and double mini-trampoline (DMT).

Trampolining today is mostly conducted in specialist gyms with certified trainers.
