Chris Hemsworth proved he is still in the prime of his life on Saturday when he flaunted his incredibly ripped physique ahead of his 41st birthday this week.

The hunky Australian actor, who stars in the upcoming animated film Transformers One, spent the day surfing in his home town of Byron Bay

Putting his very fit form to work, the Thor star was spotted carving through waves like a pro after returning home from the San Diego Comic-Con in the US.

With his sandy blonde locks in shambles as they blew through the wind, Chris was not shy about showing off his toned abs and bulging biceps.

Carrying a surfboard under his arm, the Hollywood star enjoyed his mid-winter surf with long-time friend and personal trainer Luke Zocchi. 

He was all smiles as he shared a laugh with his mate who often helps Chris hone his figure in the gym. 

Just hours before his trip to the beach, Chris was spotted touching down at Sydney airport following his trip to the USA. 

Chris made his long-awaited return to San Diego Comic-Con on Thursday to showcase the new trailer for his animated film Transformers One.
