Olivia Wilde, 40, flashes abs in a sports bra and blue leggings after hitting the gym in LA

Olivia Wilde is ready for summer and her fit figure is proving it.

The 40-year-old actress — who partied up a storm on her birthday — flashed her abs as she left a Los Angeles gym on Saturday.

She wore a tiny white sports bra and high waisted blue leggings for her afternoon workout.  

The Don't Worry Darling star threw on white tennis shoes and dark sunglasses.

Her blonde locks were worn in a high ponytail as she carried a blue sipper and a black tote bag in one hand.

When it comes to health and fitness, the star has previously said she prefers to move at her own pace, incorporating different forms of activity to her fitness regime that best suits whatever role she's preparing for at the time, according to Health Yogi.

Her workout routines typically include walking, which comes by easily considering she a New Yorker who likes to walk to her destinations as much as possible.

Indoor cycling is another exercise that Olivia includes in her lifestyle on a more regular basis.

She also likes staying active by taking advantage of her everyday scenarios; like using the stairs instead of an elevator, and walking whenever she's going to be making a series of phone calls.

During her training for her role in 2010's Tron: Legacy, she had a mix of weight training three days a week, circuit training cardio five days a week, and mixed martial arts as much as possible on workout days, since her character was doing a lot of fighting.

To improve on the mind-body connection, the New York City native adds in transcendental meditation, to go along with good mindful eating that includes being aware of what happens to her body and mind after she eats certain foods.

Though she struggles with consistency and sometimes may go off the board, but tries to return to clean eating as soon as possible.

Earlier this month, Variety reported that Olivia's next project is set to be a provocative thriller called I Want Your Sex directed by Gregg Araki.
