Zac Efron's washboard abs made another appearance on the actor's Instagram feed today, and we're definitely not complaining. The seriously buff star of the upcoming Baywatch reboot took to the social media platform to share a shirtless photo from a Ninja Warrior challenge, and it's sure to brighten up your Tuesday.

In the 'gram, Efron puts his hard-earned muscles to the test, as he attempts to lift two refrigerators with his body weight. "Special delivery for The Rock #Baywatch," he captioned the impressive shot (below).

However, Efron isn't alone in his endeavor. The Rock is also taking on the challenge to carry fridges across a beach. He shared a similar Instagram on his account, explaining the reason behind the crazy feat.

"To become a #BAYWATCH Lifeguard we created an unforgiving obstacle course that was inspired by American Ninja Warrior meets World's Strongest Man," he wrote. "All that said, it still begs one important question... Whyyyyyy in the blue hell am I carrying two massive sub zeros on my back." Good question.

Efron has worked extremely hard to get as in shape as Dwayne "The Rock" Johnson. Aside from hitting the gym and participating in Ninja Warrior training (seriously), he's also kept to a very strict diet that eliminates carbs and sugar. He may be making a lot of sacrifices, but his efforts sure are paying off.
