Having a blast! Chris Hemsworth flaunts his impressive physique and well-honed surfing skills as he catches some waves in Byron Bay 

He's known for his incredibly buff physique, having played Thor for years in the Marvel blockbusters.

And on Wednesday, Chris Hemsworth flaunted his famous figure while surfing up a storm in Byron Bay. 

The 35-year-old wore skintight swimwear for the occasion, showing off the silhouette of his perfect pecs and bulging biceps while hitting the waves.

Striking a fierce pose, Chris was seen holding on to a surfboard and splashing through the water.

He showed off a number of impressive moves - from standing upright on the surfboard to laying down for a quick dip.

The Hollywood heavyweight wore black swim tights teamed with a matching short-sleeved swim top.

He accessorised the minimal look with a glitzy large watch. 

Meanwhile, Chris launched his first business venture this year, with more than 100,000 people signing up to his Centr program and app.

Ward Blacket Investments - the investment arm of Hemsworth's management company Forward - claimed the Thor hunk took a risk to get it off the ground.

Speaking to The Weekend Australian, Trent Blacket, the managing director of Ward Blacket Investments, said the rumoured multi-million dollar deal has left the star 'heavily exposed' and forced him to 'learn quickly alongside us'.

'He has been in the weeds on this, the exact equivalent if it was a major motion picture. He has had to be because it's the first time it's his name (attached to a company),' Mr Blacket added.

Chris has become a shareholder in FLG (which includes Fitness First Australia), and FLG's chief executive Greg Oliver told the publication: 'There's been a lot of blood, sweat and tears building this.'

Chris fronts the Centr program, which sees members given access to world class trainers online, allowing them to train at home or in the gym.
