The Rock and Zac Efron Are Absolutely Crushing Their 'Baywatch' Beach Workouts

Forget about the CrossFit Games—the ultimate test of fitness is being held on the set of Baywatch, where Dwayne "The Rock" Johnson and Zac Efron have continued their onscreen battle royale with even more feats of epic strength. We've already seen these dudes flip tractor tires. What's next?

A pullup contest, of course.

 

#BAYWATCH lifeguards are the fireman of the beach. I did 100 (over hand & wide grip) pull ups and @zacefron did 99. Valiant effort from the kid, but the OG pulled thru. For now, until he dusts me in the speed round. Us #BAYWATCH lifeguards take our jobs extremely serious and we're the best of the best. We're also slightly f*cked up and dysfunctional. #IGot99Problems #ButPullUpsAintOne #OnSet #BaywatchGauntlet #BAYWATCH MAY 2017.

If Johnson's description is accurate—and there's no reason to believe it isn't—we're talking strict pullups. No kipping, no butterfly, no momentum nonsense, just man and muscle. And 100 wide-grip pullups is a lot of strict pullups. So good on you, Efron, for keeping up with 99. But this Rock can defy gravity. Well, his giant lats can.

Next up: A little American Ninja Warrior action, starring an (admittedly jacked) Efron.

 

Nothing like a little #NinjaWarrior training to start the day. Months and months of training for this moment... Bring it on @therock let's do this ALL DAY baby! #Baywatch #nowiresneeded

But no mortal man can out-awesome Dwayne Johnson. So he went ahead and one-upped himself. How? Carrying a yoke bearing two giant-ass refrigerator/freezer combos over a beach, World's Strongest Man-style.

 

To become a #BAYWATCH Lifeguard we created an unforgiving obstacle course that was inspired by American Ninja Warrior meets World's Strongest Man. Idea that you will be physically and mentally tested to the limits, all while staying focused and being as calm as possible in extremely stressful situations so you're always able to accomplish the most important thing - hit the water and make the save. All that said, it still begs one important question... Whyyyyyy in the blue hell am I carrying two massive sub zeros on my back. #WelcomeToOurFamily #WhereBadAssMeetsDysfunction #BAYWATCH MAY 2017.
