The comedian, who turned 100 last December, shed some light into his workout routine on social media, impressing his legions of fans online.

In a video shared to Instagram Aug. 29, Van Dyke could be seen laying back horizontally on an inversion table outside. Wearing a white t-shirt, gray sweatpants and slippers, the Dick Van Dyke Show alum holds onto the handles before putting his hands behind his head for a more difficult balance.

"1/2 workout inversion table," he captioned the clip. "#keepmoving"

Naturally, fans flooded the comment section to remark on his impressed they were with his agility at a century old. "You are like the Duracell rabbit," someone wrote, "that just keeps on going!! How do you do it?"

Another user commented, " Ok, it's official, the rest of us have absolutely no excuse to not be exercising!!"

Others were a bit more wary of his daring movement following the recent deaths of fellow beloved icons like Dolly Parton and Tim Curry.

"Sir, can you just take it easy," one fan said. "We had a rough week."

Another follower remarked, "Someone put bubble wrap around him please!!!"

Van Dyke is always one to keep it positive, though, and he shared some insight into his grateful outlook on life last year ahead of his milestone 100th birthday.

"I feel really good for 100," he told People last November. "Sometimes I have more energy than others—but I never wake up in a bad mood."

The Diagnosis Murder actor credited wife Arlene Silver, 54—who he wed in 2012—with helping him to stay youthful.

"She's responsible for keeping me in the moment," he explained at the time. "She kept me happy every day of my life, every day. She's a joy. She can get me singing or dancing and she carries so much responsibility ... I'm just lucky."

As for the secret to living a long life? Van Dyke wasn't so sure he could pinpoint it.

"People say ‘What did you do right?’ I don’t know. I’m rather lazy, " the Mary Poppins star admitted to People. "I’ve always thought that anger is one thing that eats up a person’s insides — and hate. And I never really was able to work up a feeling of hate. I think that is one of the chief things that kept me going.”

Van Dyke isn't the only celeb to share his workout routine, of course. Keep reading for more stars' favorite workouts...

Eight months after welcoming her daughter Matilda with Tom Pelphrey, Kaley noted why she loves doing treadmill workouts amid her postpartum fitness journey.

"Putting that incline up is so good for your muscles, and for your circulation," she told Today.com in an interview published Nov. 22. "I'll also walk backward, which is amazing for your butt and legs. It pretty much works everything."

After having a transformative year in 2023, Becky revealed how fitness played a major role. "I know at the end of the day who benefits from a healthier me the most—myself," she told E! News. "Eventually, if you dedicate yourself to it, you will have lived your life longer with this habit than you ever did without it. At least, that's the way I like to think about it."

Her go-to workouts? "If it's a home work out, if it's stretch, if it's going outside for a walk—I try to be as consistent as I can be."

The Grammy winner explained how moving to New York City helped kickstart her health and fitness journey. "Walking in the city is quite the workout," Kelly told People in an interview published Jan. 3. "And I'm really into infrared saunas right now. And I just got a cold plunge because everybody wore me down."

 Julianne told E! News the exercise she always blocks out time for when she has a jam-packed schedule.

"I know that I can walk around the hills with my dog," the Dancing With the Stars said. "That's key because I have to get her out, too. But movement in general, whether it's 10 minutes or five minutes of something, I have to move my body."

And when she has more time to break a sweat, she added, "Whether it's a Kinrgy class or doing Pilates or yoga, the fact that we get to combine all of those modalities is my favorite because I love versatility."

"I always move, even for a few minutes each day. Sometimes I'll go into a room, turn up the music and just dance. It's a great way to let loose and feel great."

The record producer opened up about his love for golfing and how it's helped him slim down.

"I do it every day and I get a chance to sit on the golf cart or walking about to answer an email or a call and handle my business," he told Us Weekly in an interview published Sept. 20. "It's so much [more] pleasurable, meaning [being around] the nature, the sun. It cleanses me."

"Honestly, my favorite way to break a sweat right now is playing VR. We got a virtual reality headset right as everything was shutting down and it's been AMAZING during quarantine. There are so many games that make you work up a sweat and it's so awesome. I am genuinely so sore after I play."

"Under normal circumstances it's going to the gym, but right now I'm taking online classes with my Pilates instructor Britni Lariviere. I'm also trying to jump rope—2,000 strokes each day."

"Family bike rides are big for us right now and I always try to carve out thirty minutes for pilates with Andrea Rodgers and foam rolling with Lauren Roxburgh."

"Running and listening to music. The best outlet I've found these last few months being stuck in the house! I feel so great and pumped up after."

"My favorite way to break a sweat is mix of sex, PRx Performance, hiking, biking."

"By connecting with my audience and motivating them through my Brooke Burke Body fitness app! I've been live streaming on the app as well as on my Instagram since the beginning of quarantine in an effort to make fitness fun and innovative. I especially love walking my viewers through total body cardio parties, which is when I crank up the music, let them find their rhythm and let the booty burn. Cardio kicks up your heart rate, so if you're not sweating, you're not working out hard enough!"

"I have been doing a lot of Sculpt, Cardio Boxing and Yoga Classes on the obé Fitness App and virtual classes with Pilates By Amanda. If I don't have a lot of time, I will do Lauren Gores' express workouts on her Instagram."

"During lockdown it's yoga under my own direction. I can go onto so many different tangents and by the time I am done it is often two hours."

"My trainer, Amoila Cesar, gets lots of results out of me by appealing to my 'no quit,' competitive side. He yells and I love it. During quarantine, I got my fix by doing his 6 Weeks of THE WORK on Beachbody on Demand. I also love a rigorous barre class and need daily yoga."

"I've been doing a lot of dancing in my apartment. I'll turn on some music and just go. Sometimes it's more structured, sometimes it's interpretive, sometimes I twerk. Also hiking!"

"My go-to work out is P.Volve, I've gone to their classes for years and now I stream them at home. I try and workout at least 3 to 4 times a week even if its for 30 minutes. Its all about strengthening and elongating your muscles. It's my favorite!"
