Jessica Simpson walks three miles a day.
The 35-year-old singer tries to get her sweat on every day by hiking with her husband Eric Johnson and their children daughter Maxwell, three, and two-year-old son Ace.
She explained: "I walk three miles a day. Eric [Johnson] and I love taking the kids out for long walks in the neighbourhood, chasing them around our yard is a work out all its own!"
The blonde beauty believes health and fitness became an important factor in her life after she became a mother.
She said: "Maintaining a healthy lifestyle is important to me. Fitness has been a priority in my life since having my kids."
Meanwhile, Jessica has just released her new active wear The Warm Up, which is part of her Jessica Simpson clothing line, in a bid to help women feel confident in their clothes by combining workout gear with fashion statement pieces.
Speaking to E! News, she said: "As with everything we do [with the JS collection], we want women to feel good in their skin and what they're wearing. Our busy lifestyles can take us from the gym to errands or out to lunch, so the styles have to be cute and versatile, but entirely functional for your workouts. It's how women are dressing today."
