The Al-Nassr forward, 38, scored his 50th goal since joining the Middle Eastern side on Friday as he dispatched a penalty in a 1-0 win over Al-Ahli.
And, despite more than 20 years in football, he still maintains a strict rehabilitation regime after games.
Ronaldo shared a picture of him lying down with his legs in a contraption made by wellness brand Erakulis.
And he added the short caption: “Recharging.”
But those on social media were more concerned with the Portugal captain’s feet.
They appeared to be bruised and swollen as he laid in front of a swimming pool at the lavish St Regis in Saudi.
Reacting to the image, one fan said: “Look at his feet man, imagine the pain everyday.”
Another added: “22 years of pro footy man look at his feet.. he wakes up with crazy pain everyday for sure.”
A third replied: “This is worse than LeBron [James], wow, I heard he used to wear super tight boots too.
