Despite being 38, a five-time Ballon d'Or winner and scorer of 873 career goals, Cristiano Ronaldo shows no signs of slowing down.
Just this week, the Portuguese superstar was spotted showing off his incredible muscles in the gym at the start of what is the Saudi Pro League's winter break.
Ronaldo's Al-Nassr side don't return to competitive action until February 14 when they take on Al-Fayha in the AFC Champions League play-offs, but he is continuing to put in the hard work.
The latest example of his relentless work ethic comes after Ronaldo ended 2023 as the top goalscorer in the world with 54 goals across club and international action.
