Imagine handing modern sports science to the icons of the past. The protein shakes, cryotherapy, wearable trackers, hyperbaric chambers, and even those weird leg compression boots—what could some of the greatest athletes in history have done with all the tools we take for granted today?
Some of these legends already dominated with far less. Give them 2025-level recovery and performance gear, and they’d be unstoppable. Here are 20 sports legends who would thrive in today’s high-tech, health-obsessed era.
20. Wilt Chamberlain

When sports science was a good night’s sleep, Wilt put up video game numbers. With modern load management and recovery tools, he might’ve played forever.
19. Bo Jackson

Bo was a walking highlight reel whose body couldn’t keep up. Today’s injury prevention and recovery advancements might have saved us from what could have been.
18. Florence Griffith Joyner

Flo-Jo already looked futuristic when she was sprinting in the ’80s. With modern nutrition and training regimens, she might still hold records nobody could touch.

The guy played through constant pain and partied harder than anyone should. Plug him into a modern training facility, and he’d be a different kind of monster.
16. Bill Walton

Walton’s feet betrayed his Hall of Fame potential. Today’s orthopedic care and performance tracking might’ve helped him dominate longer.
15. Eric Dickerson

Dickerson ran like a machine without the benefit of modern sports science. Imagine him with today’s optimized training and lighter, smarter gear.

Evert ruled the tennis court with mental toughness and relentless groundstrokes. Add strength training, hydration science, and modern analytics to her toolbox, and she’d be nearly untouchable.

Larry’s back issues were his biggest opponent. With today’s core strengthening, pain management, and preventative care, he might’ve added more years—and trophies.
12. Nadia Comăneci

The first gymnast to earn a perfect 10 did it without techy mats, personalized recovery plans, or performance tracking. With today’s tech, her perfection might have lasted even longer.

Graf had an unstoppable forehand and unmatched intensity. With today’s gear and conditioning, she’d only be more dangerous.

“Sweetness” was all heart and grit, playing through punishment every week. He’d be stronger, faster, and even harder to bring down with modern recovery tools.

Griffey’s swing was flawless, but injuries held him back. With current medical interventions and workload monitoring, we might’ve seen even more bombs and highlight catches.
5. Martina Navratilova

She had already trained like a modern athlete, which was cool. Give her access to today’s full sports science arsenal, and she’s unbeatable for a decade longer.
