And Arnold Schwarzenegger was seen sticking to his fitness regiment with a bicycle ride in Los Angeles this Thursday.

The 73-year-old former Governor Of California was joined by a pal when he was seen pedaling his way along a bike path.

Arnold zipped himself into a chessboard-stitched anorak and teamed a black T-shirt with a matching pair of sweats for his outing.

Accessorizing with a pair of gleaming sunglasses, he made sure to take the precaution of wearing a mask while emerging from lockdown.

The movie star and his estranged wife Maria Shriver share four children together – Katherine, 31, Christina, 29, Patrick, 27, and Christopher, 23.

Maria left Arnold a decade ago after it emerged that he had fathered a son called Joseph by the family’s housekeeper Mildred Baena.

Although they have been separated since 2011 and he is now dating blonde physical therapist Heather Milligan, 46, the divorce has not been finalized.

Arnie became a grandfather for the first time last summer when Katherine gave birth to her firstborn daughter Lyla by her sizzling husband Chris Pratt.

Meanwhile Joseph, 23, has followed Arnold’s footsteps to become a bodybuilder and is occasionally seen on social media with his proud father.

Last month Joseph posted an Instagram snap of himself and his father standing in front of a mural showing Arnie in his bodybuilding days as the Austrian Oak.

Joseph has now also taken his first acting role, a sci-fi comedy called The Chariot, in another career move that mirrors Arnold’s.

‘I’m following my father’s footsteps because I’m doing my own thing,’ Joseph told DailyMailTV in a recent exclusive interview.

‘I’m pursuing acting because I want to pursue acting. So really the pressure is just from myself,’ said the actor-to-be.

His hope is to ‘just focus on myself’ and ‘drown’ out comparisons to Arnie, despite the fact the Terminator star is an ‘inspiration’ to him.
