Jennifer Lopez shows off her rock-hard abs in a racy sports bra on her 4th day without sugar.

Jlo is feeling better just days after she commenced her 10-day no-carb, no-sugar challenge. She embarked on this diet journey with her boyfriend, Alex Rodriguez.

The queen took to her Instagram account a while back to announce that she would be excluding sugar and carbohydrate from her meals to keep in shape; she invited her fans to join her as she started the 10-day challenge.

And now she is only four days into the no-carb, no-sugar 10-day-challenge; she decided to post a picture of her toned abs, looking like a glazed Greek goddess.

She rocked a blue sports bra in the photo, with matching multi-patterned pants.

The caption read “Day 4 and feeling… a lil better :) Who's with me?” she wrote, adding hashtags: #10daychallenge #NoCarbsNoSugar

It has not been easy for the singer and her boyfriend, they experienced difficulty at the onset but admitted that it got easier along the way.

Jennifer Lopez complained when she just started the challenge “So it turns out, when you don't have sugar, and you don't have carbs, you're really really hungry all the time.”

She further stated that she and her boyfriend are searching for the right snacks to help them out with the persistent hunger.

Alex Rodriguez is not left out, he also used his social media to share his diet problems: “I'm on the second day of this 10-day challenge. It seemed like a great idea when I challenged all of you. I have had eggs and avocado today. I'm dying.”

But now it has gotten easier, Jlo posted a picture of the kind of food she’s been eating: it was an actual Asian bowl, the content was cauliflower fried rice, tuna poke, cucumbers, avocado, and yellow pepper.The content of the dish gave the meal a colorful look.

Jennifer Lopez has always been obsessed with fitness, and this is just one of her many means of staying fit.She hits the gym regularly and participates inconsistent yoga.

It is a breath of fresh air that she is getting her boyfriend, Alex Rodriguez involved in the challenge, although he hasn't shown his abs, he still might. The challenge is far from over

The couple has been doing a lot together, including selling their 4,000 square foot condo in New York worth $17.5 million.The condo is a luxurious high rise called 432 Park Avenue.

They repurchased the condo in February last year for a whopping $15.3 million.

The couple seems to be having fun growing together.
