Lily Allen showcases her athletic figure in a sports bra and form-fitting leggings as she works out

A few years ago, she quit smoking and changed her lifestyle.

And Lily Allen showed the fruits of her labor as she showed off her impressive athletic figure in a sports bra on Wednesday.

The singer, 37, took to Instagram to give her fans an idea of ​​what she’d been up to as she documented her recent workouts.

Showing off her toned abs in an instant, Lily chose to pair her cropped top with a pair of figure-hugging leggings.

She wore her raven locks in a very chic French bob and wore minimal makeup for her workout session.

She posed for another photo, leaning back in a stretch before donning a chunky knit sweater and taking a selfie in the mirror.
