Joseph Baena, son of Arnold Schwarzenegger, honing his posing skills

In the past, Joseph Baena has recreated several of his father's iconic bodybuilding poses, impressing fans with the resemblance he bears to Schwarzenegger's younger self. Joseph's passion for fitness has developed on its own. In fact, Arnold never pushed Joseph towards a bodybuilding career. But Joseph naturally gravitated towards lifting weights.

In a post uploaded on Instagram, Baena is seen working on her posing routine. He is joined by seasoned pros Mike O'Hearn and Robby Robinson, who share tips on how to improve his posing.

Robby Robinson is a seasoned bodybuilder in his own right. He has had a successful career and holds the title of Mr. Universe as well as Mr. America. Robby was also the inaugural champion of the Night of the Champions competition held in 1979.

Although many think that Baena is very much supported by his father, this is not entirely the case. After graduating from college, Arnold refused to financially support his son in order to take the plunge and begin to fend for himself.

Beana, however, faced the situation head on.

"I'm really grateful that my dad helped me through college."

While Joseph is an aspiring actor and bodybuilder, he decided to work in a real estate office after graduation to earn some of those dollars to start his "new life."

"I needed a job and I wasn't getting any of the acting roles I thought I was going to get, but I needed to make some money. I figured I had to do something, so I started interning at a real estate company."

Arnie's son began acting at the Los Angeles real estate firm ARIA Properties, where he still works. Beana has three other half-siblings, whom Arnold fathered with his ex-wife, Maria Shriver.
