Well, hello there Mr. Muscle...

Zac Efron is in Dubai and he's been sharing some sexy AF pics from his trip. 

The Baywatch actor, 29, looks like he's having a blast in the Middle East. He took to Twitter + Instagram to share some pics of his travels, including a pic of his biceps which look like they've been getting a little bit of TLC! 

💪🏻💪🏻💪🏻

If this is a teaser for more to come... we're definitely going to see Baywatch in theaters next month on Memorial Day weekend!
