The lean actor ran through the sand before jumping into the ocean while donning nothing but a pair of tiny black briefs.

In the brief clip uploaded for the star's 539,000 followers to see, his ripped abs and chiseled arms were clearly visible.

He wrote in the caption, "Twenty Six? More like Twenty SICK! Here's your POV of me running into my late twenties," adding a crying-laughing emoji.

The gym rat was cheerfully taking part in a fitness circuit with other people despite the cloudy weather. He had the number 743 inked on one of his strong biceps in black marker.

He was also seen sporting a red anklet as he ran alongside others under a sizable, red finish line arch. He was dressed in a faded black T-shirt, black athletic shorts, long white socks, and checkered brown and white slip-on Vans.

He smiled while writing "BDay pump" with a green checkmark emoji while posing in front of a tall mirror.

The posts come just one day after the buff DJ revealed that he had finished his first triathlon.

He posted a happy photo of himself on the beach, flexing one of his impressively toned arms.

He penned in the caption, "Competed in my first triathlon today! What a great experience it was to compete with such amazing athletes. With my birthday coming up I wanted to challenge myself in a new way, I feel like I did really well and I'm proud of myself for going the distance. I truly believe that if you have muscles, you should be able to use them!"
