The 48-year-old actress pumped some iron before lunging across the gym.
Missing from Friday's workout was Lopez's favorite exercise partner, boyfriend Alex Rodriguez, who recently opened up about their relationship in an interview with The Hollywood Reporter.
"We both appreciate where we are in our lives," he said. "We appreciate being parents, and we're so similar; we're both kind of workaholics."
