Jennifer Lopez wears burgundy athleisure on a trip to Alex Rodriguez’s new UFC gym in Miami

They arrived in Miami via a private jet on Thursday after throwing a surprise birthday party for her mother in New York City the day before.

And it was back to business for Jennifer Lopez and Alex Rodriguez as they stopped by his newly purchased UFC gym in Miami on Sunday.

The 51-year-old actress and singer highlighted her fit figure in stylish burgundy workout clothes as they fit in a workout.

Jennifer covered up with a flowing sweatshirt top with loose dangling sleeves.

It was cropped at the bottom to reveal just a hint of her washboard abs, which she otherwise covered up with dark red high-waisted leggings featuring sheer stripes over her knees.

The 5ft5in Hustlers star lightened up her sporty look with a set of white trainers and an intriguing white alligator-print handbag with brown-shaded creases.

She stayed hydrated with a silver and black bedazzled cup from Coach, and she added some style to coronavirus protection with a silver-studded mask.

Back in 2017, he announced a partnership with UFC gyms to buy one gym in Miami and to purchase the rights to construct more branded gyms throughout Miami–Dade County.

The gyms are branded by the mixed martial arts company, though they cater to regular gym users as well as professionals.

Alex was dressed in a white zip-up jacket from his own A-Rod Corp apparel company, along with black Adidas track pants and untied black sneakers.

Days earlier, she and A-Rod were up north to surprise her mother Guadalupe for her 75th birthday.

J.Lo and her fiancé documented the preparation and decorations at her mother’s home ahead of the surprise party, which was held three days before her real birthday on Saturday in order to catch her off guard.

The former Yankee superstar quizzed Lupe on her top three favorite Yankees players during the party, and though he wasn’t among them, he seemed to approve of her choices.

In addition to Alex’s recent gym ownership ventures, he and Jennifer launched a failed bid to purchase the New York Mets earlier this summer.

The two, who were joined by a group of investors, claimed to be able to nearly match hedge fund manager Steve Cohen’s $2.4 billion purchase.

However, Cohen’s ability to raise huge amounts of cash on his own, and A-Rod’s checkered past with performance-enhancing substances, ultimately led them to be passed over.
