On Thursday, the 53-year-old shared an Instagram video of a recent workout, in which she shows off a squat routine hefting an impressive stack of weight plates.

“I workout not just to help me change my body but to be strong in mind and spirit as well,” she clarified. “I have proven to myself over and over again that when you know how much you can push yourself there aren’t a lot of limits. If you are brave enough.”

Janelle added an inspiring callout at the end: “WHAT HAVE YOU DONE THAT PROVED EMPOWERING?”
