The Miracles from Heaven star looked happy and confident as she left her dance workout session at Body By Simone in her Los Angeles neighborhood on Friday, carrying her workout towel, clipboard and green juice.
Earlier in the day, Garner's candid interview with Vanity Fair, in which she opens up about her divorce from Ben Affleck, went wide.
"It was a real marriage," she told the magazine in its latest cover story. "It wasn't for the cameras. And it was a huge priority for me to stay in it. And that did not work."
The actress also addressed reports that Affleck had an affair with the family nanny – claims he has adamantly denied.
"We had been separated for months before I ever heard about the nanny," Garner revealed. "She had nothing to do with our decision to divorce. She was not a part of the equation. Bad judgment? Yes."
Despite the difficult divorce, Garner says she still has feeling for the father of her children and has no regrets about marrying Affleck. "I would go back and remake that decision ... You can't have these three babies and so much of what we had. He's the love of my life."
