Naomi paired her leggings with a beige hooded top featuring an artistic design on the front.
The Vogue covergirl had a black designer handbag with gold detailing in the crook of her arm that coordinate with her chic sunglasses.
She wore her lengthy brunette hair down and styled in mermaid-inspired waves that cascaded down her back and chest.
She strolled down the sidewalk in a pair of blue, gold, and white Nike sneakers and a water bottle in her hand.
Campbell accessorized her workout-ready look with several bracelets, rings and a pendant chain.

Before heading inside the Pilates studio, the 5foot10inch beauty tossed her cellphone into her purse.
Naomi's outing on Wednesday comes a little less than two months after she shocked fans by revealing she had welcomed a daughter.
She announced the news on Instagram by sharing a picture of her newborn's feet alongside the caption: 'A beautiful little blessing has chosen me to be her mother.
'So honoured to have this gentle soul in my life there are no words to describe the lifelong bond that I now share with you, my angel. There is no greater love.'
Friends have also told The Daily Mail that they believe Naomi – who never knew her father and was raised largely by her grandmother – used a surrogate.
