A large monitor lizard casually wandered around a park amid weightlifting locals.

Footage shows the 5ft-long chubby reptile crawling across Lumphini Park hoping to scale up on its fitness.

At the park, there was free-to-use gym equipment such as dumbbells and workout benches in Bangkok on March 15.

Asian water monitor lizards normally live in canals, swamps, sewers and ponds in cities in Thailand. They feed on fish, snakes, frogs and scraps of food left by humans.

The reptiles are aggressive when threatened and have a mildly venomous bite which sometimes carries harmful bacteria. The Godzilla-like reptiles are also a protected species in the country so their population thrives.
