The Dancing With The Stars host told Shape magazine that she's begun to possess a greater knowledge of her own strengths and weaknesses as she's grown older.
"It's really about being comfortable in your skin at every age," she said.
Burke added: "I feel better now than I ever have before. I feel stronger, I feel more confident, I feel healthier. I feel like I know my body better."
The TV presenter also insisted that she uses exercise to help keep her grounded when her life becomes hectic.
"I do it for energy, I do it for stress… I do it so I can have a little bit of me time in my crazy day, it keeps me sane," the star noted.
Earlier this week, Burke also revealed that frequent exercise is key to increasing her sex drive.
