Bodybuilding legend Dexter Jackson may have retired from competition five years ago, but judging by his recent gym footage, his passion for the iron hasn’t faded one bit.
At 55 years old, the 2008 Mr. Olympia winner still sports a physique that puts men half his age to shame — and he’s making it clear that age is no excuse for falling off the fitness wagon.
Fans are calling him ageless. But is it just genetics, or is there more behind Jackson’s timeless form?
Here’s what his latest training clips reveal — and what everyday lifters can take away from one of the most consistent bodybuilders in history.

Still Shredded and Strong at 55
In a recent Instagram video, Jackson shared a full-blown arm session that had social media buzzing. It wasn’t just a casual workout. Jackson attacked a lineup of exercises with the kind of intensity that made him a legend.
Highlights from the video included:
- Machine preacher curls
- Barbell curls
- Spider curls
- Two variations of triceps pushdowns
- Diamond push-ups
Even without the stage lights or the pressure of competition, “The Blade” trains like he’s still prepping for the Olympia. He didn’t reveal his current weight, but judging by the footage, he still holds more muscle than most men in their prime — let alone in their mid-50s.
Hip-hop legend Busta Rhymes and seven-time Mr. Olympia Phil Heath were among those hyping Jackson up in the comments. And with biceps still ballooning and veins popping, it’s easy to see why.
No Comeback — But No Slowdown Either
Despite the speculation that followed the viral workout video, Jackson quickly shut down any whispers of a comeback.
“Still hard at work even while retired,” he posted, firmly drawing a line between passion and competition.
That discipline — pushing hard without the promise of a trophy — may be Jackson’s most impressive flex. It’s not about titles anymore. It’s about longevity, health, and setting the standard for what’s possible at 55.
Career of a Bodybuilding Icon
Few names in bodybuilding history come close to Dexter Jackson’s legacy. His pro career spanned from 1999 to 2020, during which he faced — and often beat — giants like Ronnie Coleman, Jay Cutler, and Phil Heath.
His most iconic win? The 2008 Mr. Olympia, where he dethroned Jay Cutler in one of the most memorable upsets in bodybuilding history.
Other standout achievements include:
- Five Arnold Classic wins (2005, 2006, 2008, 2013, 2015) — a record in the men’s open division
- Masters Olympia winner in 2012
- 29 professional wins — the most in men’s bodybuilding history
He’s also the only athlete to win all three major titles: Mr. Olympia, Masters Olympia, and Arnold Classic.
Building a Legacy Beyond the Stage
Jackson may have stepped off the stage, but he hasn’t stepped away from the sport.
His Dexter Jackson Classic returns July 29, 2025, in Jacksonville, Florida. The National Physique Committee (NPC) amateur event includes men’s and women’s divisions, as well as a new “Fit Model” category — proving Jackson’s still invested in evolving the sport and giving back.
He’s also active in the supplement game with his Dexter Jackson Signature Series, which continues to grow in popularity among fans who want to emulate his results.
What Jackson’s Routine Teaches About Longevity
Jackson’s current workouts reflect a few key principles that anyone over 40 — or even 30 — can benefit from:
1. Consistency Over Intensity
While Jackson still lifts heavy, his form and focus stand out more than raw weight. He hits every rep with intent, showing that longevity comes from smart training — not just hard training.
2. Body Part Isolation Works
His workouts often focus on single muscle groups like arms or shoulders, using classic isolation movements. This helps prevent injury and maintain muscular detail without overloading joints.
3. High-Volume, Controlled Reps
Jackson isn’t chasing PRs. He’s chasing the pump. High reps, short rest, and full control create deep muscle fatigue — and visible results.
4. Stay in the Game Mentally
Retirement hasn’t dulled his edge. By staying involved with contests, supplements, and his social media community, Jackson maintains a competitive mindset — and that keeps his body sharp.
Not Alone in His Prime-Time Comeback
Jackson isn’t the only 2000s-era bodybuilder still looking elite.
- Jay Cutler, now 51, recently revealed a jaw-dropping transformation ahead of his last birthday, showing that his commitment to fitness remains high.
- Dennis Wolf, at 46, still trains and diets year-round, keeping a lean, detailed physique that continues to impress fans.
These athletes prove that with structured training, discipline, and smart recovery, the aging curve can be bent — if not broken.
The Takeaway: Yes, You Can Stay Jacked in Your 50s
Dexter Jackson is a walking, curling, flexing testament to the idea that aging doesn’t mean decline — not if you keep training hard and smart.
He’s not chasing trophies anymore. He’s chasing legacy.
And in doing so, he’s showing the world that 55 is the new 35 — at least when you’re built like “The Blade.”
For anyone worried about getting older in fitness, let Jackson be your reminder: the real competition is with yourself, and that never retires.
