Olivia Wilde bares her washboard abs in burgundy sports bra and leggings as she leaves her daily gym session

Olivia Wilde showed off her impressive flat abs as she left her Los Angeles gym on Thursday.

The 40-year-old filmmaker — who packed supply kits for Baby2Baby this week — was clad in a burgundy sports bra and matching leggings.

The stylish, skintight spandex had a single white stripe going down the leg and she added white HOKA sneakers.

The mother-of-two pulled her dirty blonde locks into a ponytail that bounced as she walked.

She kept her belongings tucked away in a beige and red tote bag that she draped over her shoulder.

The Hollywood mainstay was makeup-free and wore a pair of black Ray Ban sunglasses over her eyes.

Wilde is a regular at Tracy Anderson Method Studio in Studio City.

She joined Kelly Rowland and Ciara earlier this week at the Baby2Baby maternal health press conference in LA.

The trio assembled and carried the Newborn Supply Kits which contained diapers, hygiene products, breastfeeding supplies and postpartum care resources.

Olivia shared her thoughts about the cause with her 4.1 million Instagram followers after the event.

The silver screen siren posted a black and white image of herself at the conference and added a thoughtful caption. 

‘Mental health struggles are the leading cause of death for new mothers in the US, and the rate of those deaths has doubled in the last 20 years!’ she wrote.

She added, ‘We need to restore the village mentality and help each other out. Public and private sector partnerships are smart and effective when launching these massive programs to reach as many mothers as possible.’

The note continued, ‘Today @baby2baby packed essentials kits for new moms, including all sorts of stuff no one tells you you’ll need. Major thanks to @hhsgov, for designing this program, and @huggies for making it possible. 

‘I hope we can take it to every state next Mother’s Day,’ she finished the post.

Wilde also used her Instagram Story to share how important the cause is and how ‘proud’ she was to have helped the companies.

‘Mother’s day always makes me feel connected to other Mothers, and this year all I’m thinking about all the new moms who are struggling. It’s fu**ing hard. And you’re not alone,’ she wrote behind a snap of herself after giving birth.

She also added a shoutout to Kelly and Ciara for packing the kits and launching the program alongside her.
