But she didn't get that ripped body by taking too many days off. In 2015, Jennifer told Us Weekly that she “very rarely skips a workout."

The entertainer, who has a residency show in Las Vegas called "All I Have," spends a lot of her time dancing on-stage, but she's not opposed to breaking a sweat the old-fashioned way: at the gym.

"Sometimes when I get home and I'm not feeling so great, I make myself go to the gym," she told Redbook in 2010. "Then I come home and take a shower, put on a great outfit, some makeup, tie my hair up, and I feel pepped up and great about myself."

"She’s genetically blessed, she’s physically gifted with an incredible amount of physical energy, but also this beautiful amount of mental and emotional energy," her trainer, David Kirsch, told People in 2017. "She’s very connected to her body, and she’s got crazy discipline."
