Jessica Simpson showed off her incredible figure in two pictures shared on Instagram Monday. The fashion designer is seen in workout gear in the pictures as she gives fans a glimpse of her new campaign for her activewear line, The Warm Up. It is a mix of activewear and athleisure, which is part of her Jessica Simpson collection.

Simpson took to Instagram and posted a picture of her. “Lunge your bunz into @macys and get The Warm Up by @jessicasimpsonstyle #macysexclusive,” she captioned the picture. The picture shows her wearing a teeny tiny pair of black shorts and a matching long sleeve top.

The top features a scooped back and a T-back detailing. She also wears a green and animal patterned T-back below the top. Jessica holds dumbbells in her hand and her long blonde hair is tied in a ponytail. She shows off her long toned pins in the picture.

Two pictures were shared on Jessica Simpson Style Instagram account on Nov. 20. The first picture shows Jessica sitting on the floor on a yoga mat wearing a black, printed and pink capri and a matching top. In the second picture, she wears a pair of workout capris and flaunts her seriously toned calf muscles.

The designer wears black trainers and a skipping rope lies beside her on the floor, as she strikes a pose for the camera. Jessica’s The Warm Up includes leggings, sports bras and track jackets. The track jacket, Extraordin-Air, is composed of a polyester-spandex blend that incorporates both sweat-absorbing capabilities and four-way stretch.

Her products are available at a very reasonable pricing range of $24 to $49. The line is available exclusively at 300 Macy’s stores and at This is Simpson’s first major expansion after her label partnered with Sequential Brands in April.

According to Jessica, her line is “a blend of great active features, technology and fashion.” She said that The Warm Up is made to flatter any body type. The mother-of-two added that the line has been created to wear in the gym to errands and also to lunch.

With the launch of the activewear line, the pop star-turned fashion designer’s lifestyle brand will witness its first major expansion into a branded collection. The line will be available to other retailers next spring.

The 35-year-old stays in shape by walking three miles a day with her husband Eric Johnson and the kids. She also does squats and uphill lunges.
