The Grease actor is proud of his son Ben's achievements though, and has documented in the past that Ben was a budding gymnast and Ninja Warrior fan.
In August one video showed Ben hoisting himself up stairs with his hands and making leaps onto bars.

John couldn't have been more elated to share his son's feat, writing alongside his post: "Ben just achieved a level 3 ninja and I'm so proud."
In September John poured his heart out in a touching social media post about his family with the 68-year-old filming himself selfie-style to share with fans.
"I was thinking this morning how important achievements and abilities gained or regained are to one's life. And you all have been so appreciative of mine, and my daughter's and my son's achievements and I wanted to thank you for going out of your way to do so," he said. "And to remind you that Ben is on Instagram, and I love you for always staying with me. Thank you."
He then tagged Ben's Instagram account, which shows off his gymnastic skills.
