Gym buffs have a reputation for being aggressive and ‘roid raging’.

But this balletic body builder is a law until himself.

During the journey to beef up his chiselled body, it seems Vadim Skornyakova has taken the time to learn the jive, the moonwalk, the funky chicken, and Indian-style dance.

And having built up quite the repertoire, he knew just the place for his debut: Russia’s body building tournament.

Competing for the title at Saint Petersburg’s 25th Cup Championship, Mr Skornyakova took to the stage before a room of rivals to strike his mandatory poses.

But the competitors and their families were left open-mouthed as he, instead, burst into a fully-fledged dance routine.

He emerges on to the stage sideways, with arms outstretched in the style of traditional Indian dance.

For good measure he throws in some classic body building poses – before jumping into some token jive moves that celebrity contestants on Strictly Come Dancing strive to master.

Singing along to the music – now a primary school song – he completes the performance with a moonwalk, some kicks and an artful spin before skipping off, leaving his competitors screaming and applauding.

The Russian video has attracted viewers from all over the world, mesmerised by Mr Skornyakova’s technique.

The host shakes his head in disbelief saying: ‘Well… Vadim is an incredibly positive person!’

One fan wrote on YouTube: ‘He had so much fun, this is so inspiring.’

Another said: ‘I hope he won. I will be watching this again.’
