Jennifer Lopez and boyfriend Alex Rodriguez recently hit the gym for another round of rigorous workout.

On Tuesday, Lopez, 49, and her former pro baseball player beau, 43, were photographed leaving a gym in Miami. Lopez flaunted her toned abs in a tight, bright pink top with long sleeves and sheer panels on the shoulders and gray leggings that are see-through on the sides in photos released by Daily Mail. The singer-actress piled her hair on the top of her head in a bun and completed her look with black trainers.

Meanwhile, Rodriguez looked very sweaty after their rigorous routine, wearing a navy shirt and matching track pants for their time at the gym. Lopez and Rodriguez were joined by Olympic swimmer Ryan Lochte and his pregnant wife, Kayla Rae Reid.

Last month, Lopez and Rodriguez took on the 10-day challenge, wherein they eliminated sugars and carbs from their diet for this period of time. The singer posted a video on her Instagram on Jan. 24 in which they challenged some of their friends to follow their diet.

Lopez also continued to update her followers on the results of the diet and her workout, sharing photos of her toned figure on the fourth and ninth days of the 10-day challenge.

During her recent interview on "The Ellen Show," Lopez told host Ellen DeGeneres that she had been challenged by her trainer to avoid eating sugar and carbs. The singer added that while she found it difficult at first, she would be willing to go on this diet again because she found that she craved less sugar after the 10 days were up.

It seems Lopez may have actually started a second round of the 10-day challenge as a source told Page Six that she and Rodriguez turned down the famous Mark Light Shakes during a University Of Miami baseball game over the weekend.

While she has always been passionate about keeping fit, there's a reason why Lopez has been working extra hard these days. Lopez has been training hard in preparation for her role as a stripper in the movie "Hustlers." Earlier this week, Rodriguez filmed her practicing a pole-dance performance to the song, "(I've Had) The Time of My Life," and shared the video on Instagram.
