The latest: Arnold Schwarzenegger’s son Joseph Baena continues to follow in his father’s fit footsteps. The second-generation bodybuilder, 23, took to Instagram Tuesday posing in a clip to showcase his physique, writing, ‘Having fun running through some movements!’

Baena continued to grind days after his dad made headlines remarks on social media condemning those who took part in the riots; and President Donald Trump, who he said ‘will go down in history as the worst president ever.’

Schwarzenegger, who served as the Governor of California from 2003 until 2011, compared the deadly invasion to the Nazi’s 1938 invasion of Jewish homes, businesses and places of worship on Kristallnacht.

Schwarzenegger said, ‘Wednesday was the Night of Broken Glass right here in the United States … the broken glass was in the windows of the United States Capitol.

‘But the mob did not just shatter the windows of the Capitol, they shattered the ideas we took for granted,’ he said. ‘They trampled the very principles on which our country was founded.’

He said that ‘President Trump sought to overturn the results of the election – and of a fair election, and that he sought a coup by misleading people with lies,’ adding that the 45th president ‘would soon be as irrelevant as an old tweet.’

The action star noted, ‘To those who think they can overturn the United States Constitution, know this: You will never win.’ 

Baena is Schwarzenegger’s son with his one-time housekeeper-turned-mistress Mildred Baena. In October, the Kindergarten Cop star took to social media praising Joseph for his dedication to fitness.

‘Happy birthday @projoe2! I love watching your progress with your training, your work, and in every part of your life,’ he wrote. ‘I can’t wait to see what’s coming next. I love you!’

The ex-California governor, 73, is also dad to sons Patrick, 27, and Christopher, 23, and daughters Christina, 29, and Katherine Schwarzenegger Pratt, 31, all of whom he shares with ex-wife Maria Shriver, 65.

Schwarzenegger and Baena, prior to the lockdown, had regular workouts at Gold’s Gym in Venice Beach, California, where Arnold’s star rose as a seven-time Mr. Olympia ahead of his Hollywood breakout. 

They have since been seen on bicycling outings in Los Angeles, as Schwarzenegger has with his other kids amid the pandemic lockdown.
