Jennifer Lopez has been spotted heading to the gym in Miami flaunting her stunning form in a pair of skin-tight leggings.

Her high-waisted tights, courtesy of the singer’s favourite brand Beyond Yoga (which can cost upwards of $145 a pair), were teamed with futuristic mirrored sunglasses, also in pink, a relaxed ponytail and box-fresh white trainers.

The 50-year-old completed the effortless look with a cute cropped sweatshirt that showed off her incredible abs.

Lopez, who is known for her style, teamed her workout combo with nails, lipstick and a smartphone cover, all in a soft pink hue.

In preparation for her most recent movie Hustlers, JLo told fans she’d given up sugar and carbs as part of a ten day challenge.

Cutting the two food groups was a suggestion made by her trainer, Dodd Romero, to help her prepare for her role, she said on an episode of The Ellen Show.

“(The challenge) was really hard. Not only do you get a headache, but you feel like you’re in an alternate reality or universe. Like, you don’t feel like yourself. You realise that you’re addicted to sugar,” she said.

In January she also shared a snap of one of her carb and sugar free meals, an Asian bowl, comprising of cauliflower fried rice, seared tuna, shaved brussel sprouts, yellow pepper, avocado and cucumber.
