Brooke Burke, 51, shares her favorite tips to staying in shape during the holidays

Brooke Burke, a former host on "Dancing with the Stars" is a fitness enthusiast who launched her workout app Brooke Burke Body in 2017. She's since launched Longevity.

In 2017, the mom of four developed "Brooke Burke Body," an app that features hundreds of "stackable" workout programs ranging from five to 30 minutes that can be done anywhere without equipment. Her goal, she said, was to make exercise more accessible to busy moms struggling to carve out time for themselves. Stephanie Nolasco covers entertainment at Foxnews.com.

"I think one of the most common mistakes is people don’t know where to begin," the 51-year-old told Fox News Digital. "They lose their sense of self, their self-confidence. They don’t know how to create change. So then they do nothing, which would be the biggest mistake… If you’re not feeling certain about how to start changing your body, just do something. Take a walk, start small… Doing something is better than nothing. It’s the most common conversation that I have with women."
