Celebrity Muscle - A Glance at the Stars Staying in Shape

By Roger Lockridge

While bodybuilding is considered the epitome of physique presentation, there are a lot of celebrities outside of the sport that stay in great shape and inspire their fans. They stay just as dedicated to getting the work in showcasing the results as anyone who prepares to take the stage.

We decided to pay homage and show respect for these incredible folks by shouting them out here on Muscle Insider. Take a look at just a few of the stars showing up and looking good!

Dwayne “The Rock” Johnson

The Brahma Bull has been an athlete all his life, going back to his days in college football to entertaining the millions...and millions of fans in the WWE. He recently celebrated massive success with the release of his latest film Black Adam. Clearly, he isn’t resting on his laurels as shown by this pic of “The Great One” after a hard leg day.

On another note, Johnson and his team at ZOA Energy just recently celebrated another moment, their release of the popular energy drink in Canada. Try the Cherry Limeade if you get a chance. You won’t regret it.

Zac Efron

Former Baywatch film star Zac Efron is preparing for another role as the wrestling legend Kevin Von Eric in the film dedicated to this Von Erich family. As you can see, Efron has been putting in the work in both the gym and at the kitchen table, because he’s as muscular as he’s ever been. The photo above shows Efron as well as the original, Kevin Von Erich from his heyday in the 1980’s. Clearly, Efron takes his roles very seriously and the fans of the iconic Texas family would be proud of the results.

Mark Wahlberg

Johnson’s former co-star in Pain and Gain, Mark Wahlberg is a former Olympia Ambassador, and he’s been getting attention for his physique development since the early days of his music career. The 51-year-old still gets after it, and he shares a little of that in this video where you can see his calves and arm development while congratulating the Houston Astros for making the World Series.

Halle Berry

Halle Berry has starred in many roles, and her fitness has been a big component for a lot of those. In this throwback tribute to her role as Cat Woman, you can see why she became a leading lady in Hollywood. She still promotes fitness occasionally on her Instagram, which is definitely worth a follow. If you want to see her show her fitness in epic form, watch her 2020 film, Bruised.

James Harrison

James Harrison is a sports analyst nowadays, but he was at one time one of the most feared defensive players in the NFL. He still puts in the work, and even finds unique ways to celebrate his birthday. For his 42nd birthday, he took on a max weight challenge by pushing 42 plates on a push sled. Counting the weight of the sled itself, that’s 1,960 pounds he is moving with his own muscle and will. He’s probably gotten a couple of calls from teams since this video dropped.

Arnold Schwarzenegger and Sylvester Stallone

These two icons are considered founding fathers of muscle in the movies. There may have never been two bigger stars in Hollywood than Arnold and Sly. They’ve been great friends as well, and they hung out recently, taking some time to analyze a couple of swords. Even in their 70’s, fitness is still a big part of their lives, as Arnold shows with his arms while holding his weapon of choice.

Schwarzenegger has been working on a Netflix series called FUBAR, filmed in Toronto, while Stallone will be starring in Tulsa King, premiering on Paramount Plus in the US during the month of November.

Sophia Jurksztowicz

We had to shout out Canada while we’re doing this, and no one serves as a better choice than renowned sportscaster Sophia Jurksztowicz. The Ontario native has covered multiple sports, and she is currently a reporter and interviewer for NESN in the New England area of the US. She’s also an advocate for fitness and health, which she talks about often on her social media. Check out her abs in this image while promoting the option to train outside.
