Jennifer Lopez, 57, shows off her incredible figure in curve-hugging post-workout look

Jennifer Lopez is proving once again that her gym style is anything but ordinary.

The 57-year-old singer and actress was spotted arriving for a workout session in Calabasas, California, on August 19, stepping out in a sleek all-black look that highlighted her famously toned physique.

Lopez wore a fitted black activewear jumpsuit featuring a halter neckline, plunging scoop front and an open-back design. The body-contouring one-piece continued into full-length tapered leggings, creating a streamlined silhouette as she made her way to her workout.

The singer kept the rest of her look sporty and effortless, pairing the jumpsuit with white crew socks and white low-top training sneakers. She accessorized with oversized aviator sunglasses, small earrings and a delicate gold necklace.

Her beauty look was equally low-key. Lopez swept her highlighted brunette hair into a high ponytail, keeping it away from her face ahead of her training session. She appeared to wear minimal makeup for the outing and was photographed carrying a takeaway drink.

Jennifer Lopez's dedication to fitness:

Lopez has long made exercise a consistent part of her lifestyle, and her latest appearance offered another glimpse at the results of that dedication.

Over the years, the multihyphenate has incorporated different forms of training into her routine, from strength and resistance work to dance-based workouts.

Her demanding stage performances also require considerable stamina, with choreography remaining an important part of her career decades after she first emerged as a dancer.

Her latest gym look also reflects Lopez's signature approach to athleisure. While the star frequently embraces glamorous gowns, towering heels and statement-making red carpet fashion, her off-duty wardrobe often combines practical workout pieces with polished accessories.

This time, the monochromatic jumpsuit did most of the work, while her aviators, jewelry and high ponytail gave the workout-ready ensemble a distinctly JLo finish.

At 57, Lopez continues to make fitness a visible part of her everyday routine, and her latest Calabasas outing showed that her gym wardrobe can command just as much attention as her red carpet style.

Amal Clooney Wore Optical Illusion Jeans Cosigned by Jennifer Lopez—Fall-Ready Styles Start at $44

My list of must-try jean trends for 2026 is growing; it currently includes all the silhouettes one denim expert revealed to me as the must-watch of the year (save for baggy jeans, because I’ve been wearing those for years). That said, one style that didn’t land on said aforementioned list, but is clearly due for big, big things this year, is flare jeans. With a growing list of celebrity fans that includes Meghan Markle, Jennifer Lopez, Reese Witherspoon, Cindy Crawford, Kendrick Lamar (you know that moment), and, of course, Amal Clooney, there’s no denying the retro denim style that was popular in the early aughts is back—and bigger than ever.

The fact that Clooney wore flared jeans is noteworthy in and of itself. The human rights lawyer is known for her refined dressing approach, regularly opting for billowy trousers, trendy boho blouses, and comfy sweater dresses—all staples that read elegant and timeless. So, when I spotted her earlier this year in the laid-back blues while out to dinner with hubby George Clooney, I knew I had to write about it. Of course, the fact that she wore flare jeans, the style countless celebs have worn the last few weeks, is noteworthy, too, as it further cements the style’s ‘It’ status for 2026.
