A walrus performing sit-ups amused zoo visitors in China.

Holidaymakers were stunned to watch the tusked seal exercising during the show at Chimelong Ocean Kingdom in Zhuhai, Guangdong.

Footage shows a trainer signalling the talented animal to roll over on the ground and place its flippers behind its head on March 19.

It then curled its torso upward after the worker lifted his hand in the air.

Vacationers can be heard yelling in awe and applauding as they witness the walrus's talent.

Walruses are intelligent marine mammals that can learn behaviours through positive reinforcement and form strong bonds with trainers, recognising voices and responding with excitement like sea lions or elephants.
