Arnold Schwarzenegger and his kids Patrick and Christina take a family bike ride

He’s cultivated a culture of fitness among his children.

And Arnold Schwarzenegger used his passion as a bonding activity on Saturday as he went for a bike ride in Santa Monica with his children Patrick, 27, and Christina, 29.

The former California governor may have summed up his approach to public service with an inspirational quotation on his T-shirt that’s attributed to Theodore Roosevelt: ‘Do what you can with what you have where you are.’

Family outing: Arnold Schwarzenegger, 73, was spotted riding his fat bike in Santa Monica on Saturday with his son Patrick, 27, and his daughter Christina, 29

Arnold matched his charcoal shirt with black pants and had on a pair of white Adidas trainers to lighten up the look.

He stayed warm early on their ride with a black fleece jacket, though he tied it around his waist later. 

His son Patrick was also dressed for a workout and the breezy air with a gray hoodie and black athletic pants. 

The Daniel Isn’t Real star sported a shaggy quarantine hairdo that flitted about in the wind under his black baseball cap.

Christina got in the spirit for a bike ride with a black Harley Davidson T-shirt, and she completed the muted look with black leggings and a black baseball cap.

Both of the younger Schwarzeneggers skipped masks for their outdoors exercise, but the Terminator star had a black mask on throughout parts of their ride.

The children were cruising on slender street bikes, but Arnold opted for a fat bike, which has larger tires with thicker rims and a heavier, sturdier frame that makes it ideal for off-road excursions.

The former bodybuilder has long been a cycling enthusiast, but it has turned into a relatively safe way for the 73-year-old to spend time with his family, especially as he’s at greater risk of complications from COVID-19 due to his age.

‘Thanks to the team at the Cleveland Clinic, I have a new aortic valve to go along with my new pulmonary valve from my last surgery,’ he wrote on Instagram as she shared a thumbs-up photo from his hospital bed.

‘I feel fantastic and have already been walking the streets of Cleveland enjoying your amazing statues. Thank you to every doc and nurse on my team!’

Missing from the outing was his daughter Katherine, 30, his sons Christopher and Joseph Baena, both 23.

Schwarzenegger had been married to Maria Shriver since 1986, but the marriage ended in 2011 after she discovered that he had fathered Joseph 14 years before with one of their household employees.

Despite the infidelity, he regularly spends time with most of his children, and he and Joseph often lift weights together.
