Jennifer Lopez works hard to keep her body fit and toned, so it's no surprise that the singer-actress has no qualms about showing off the results of her efforts.

Lopez, 49, recently stepped out for two outings with her twin children, Max and Emme, 10, in Miami. In photos released by Daily Mail, Alex Rodriguez's girlfriend wore a bright yellow, long-sleeve crop top, colorful leggings and white running shoes for her outing with Emme. The singer-actress piled up her hair on the top of her head in a high bun and completed the whole look with a pair of large sunglasses and a yellow handbag.

Her daughter, Emme, chose a less vibrant look for their outing, wearing a black and white t-shirt and black overalls.

Later in the day, Lopez stepped out for another outing, this time with both of her twins. She also had an outfit change, this time wearing gray workout clothing that showed off her hard-earned abs. The outfit consisted of a tight long-sleeve crop top and gray leggings that hugged her figure.

Lopez accessorized this look with large gold hoop earrings, another pair of large sunglasses and a white handbag.

Lopez posted a photo of her earrings on her Instagram page following their outing, revealing that the large gold hoops had her name on them.

Meanwhile, Lopez also hasn't been shy about flaunting the results of her diet and exercise on social media. Just recently, she and Rodriguez completed their 10-day challenge wherein they took out sugar and carbs from their diet for 10 days.

Lopez, who recently gave a fantastic performance at the Grammys, posted a photo of herself just a day before completing the 10-day challenge, showing off her rock-hard abs in a bikini top and leggings.

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

Lopez has been busy getting fit for her role in the upcoming movie, "Hustlers at Scores," where she will reportedly play a stripper.​
