Dong dreams of jumping at one more Olympics

Chinese trampoline star Dong Dong has spent his life defying gravity, but now he wants to defy his age as he trains to participate in a record-tying fourth Olympic Games in Tokyo in 2020.

Dong, 29, has reached the podium in all his previous Olympic appearances, winning bronze at the age of 19 in Beijing in 2008, gold in London four years later and silver in Rio in 2016.

But he's leaping at the chance to somersault his way into the Tokyo Games, which would make him the first male trampolinist to participate in four Olympics.
