At 40 years old, Cristiano Ronaldo continues to defy football’s physical limits. This season with Al-Nassr, the Portuguese forward has already scored 33 goals in 39 matches, proving that age is just a number when you’re in elite condition. Now, a new revelation has reignited the conversation around his future: according to health tech company Whoop, his physiological age is just 28.9.

Elite Performance With a Twenty-Something Body

A brand ambassador for Whoop, Cristiano Ronaldo reacted with amusement to the results: “28.9... that means I’ll be playing football for ten more years,” he said. The data, based on metrics like heart rate variability and sleep quality, confirms the legendary striker is still performing at a level far beyond what is expected for his age.

It’s not the first time Ronaldo’s physical stats have stunned the world. When he signed for Juventus in 2018 at the age of 33, medical evaluations showed his body was comparable to that of a 23-year-old. With just 7% body fat and 50% muscle mass—both exceptional even for elite athletes—his fitness set a new benchmark. During his unveiling, he famously joked: “I’m honored by Juve’s trust... now that I’m 23.”

A Possible Return to Europe?

Though currently competing in the Saudi Pro League, Cristiano Ronaldo’s outstanding condition and relentless drive have reopened speculation about a potential return to Europe. “When you’re young, you think you’ll live forever. But now, I prioritize sleep and recovery much more,” he explained.

With his scoring numbers still soaring and his discipline unmatched, Ronaldo’s message is clear: retirement is not on the horizon. In fact, he’s openly entertaining the idea of playing until 50. With several European clubs seeking veteran leadership and global appeal, the prospect of his comeback is gaining traction.

Cristiano Ronaldo’s physical and mental durability continues to expand his legacy. And in a football world that thought it had seen everything—he proves there’s always more to come.
