Even though The Rock likes to have a laugh, he still gets his work done in the gym. The star, aka Dwayne Johnson, is currently in Budapest shooting Hercules: The Thracian Wars. He recently tweeted his Hercules diet and workout pics and today took to Instagram to post a quick video of his back workout. Here is how he describes it:

“Slab training (back). High volume. 4 sets. 15+ reps. Every final set is a 2x drop set. Remember to randomly shout “FOCUS” & scare the sh*t outta people. End workout with a maniac flex & brush that dirt off your shoulders. Have fun. #SmileIsOptional #Budapest #HERCULES”

You’ve got to hand it to the man, he always seems like he is having a blast! Check it out:
