Jennifer Lopez flaunts her sweaty toned body while challenging fans to go 10 days without sugar

Jennifer Lopez and her boyfriend Alex Rodriguez have challenged fans to a health challenge. The pair enticed followers in a workout video via Instagram.

On Saturday, Rodriguez shared a clip of him and Lopez working out to club music. The two looked determined as they did several exercises. They were helped by a trainer in the gym.

For the display, Rodriguez wore a blue t-shirt and black tracksuit pants. His singer girlfriend stunned in a black exercise top that showed off her toned abs. The clip is found below.

She paired the upper piece with black leggings that featured netting running down her legs on the side. She topped it off with neon orange sneakers.

In the clip, Lopez stopped at one point to show off some dance moves. She encouraged Rodriguez to join in on the fun. The pair looked adorable in the moment.

Rodriguez implored fans to join them for a 10-day challenge in the caption:

"We pinky promise. Join me and Jennifer for a 10-day challenge. No carbs, no sugar. Who's in? Challenge two of your friends below. Someone hide the cookie dough. #ignore my dancing."

Rodriguez, a former pro baseball player, clearly has a good sense of humor. He showed more of it last week Wednesday when a Lopez fan described him as "the guy that J.Lo's dating."

Rodriguez shared a clip of what happened when the woman spoke to him.

She said:

"Yeah, A-Rod, Alex Rodriguez. There we go."

When Rodriguez asked, "Who's that?" she responds: "That's the guy J.Lo's dating."

Rodriguez then said:

"You're kidding me. And he looks like me?"

With that, the woman opened up google and goes through some images of Rodriguez. It dawns on her that the man she thinks is a look-a-like is Rodriguez himself.

Rodriguez finally stood up, shook her hand, and said it's nice to meet her. In response, the woman said, "Holy [expletive]!"

Of course, Lopez will continue to hold the spotlight in her relationship. She still has an ongoing career. Plus, she continues to stun with her gorgeous body.

In mid-January, she graced the cover of Harper's Bazaar wearing a red one-piece with a black cloth belt. Inside, she flaunted a black cutout swimsuit and appeared to be flying as she took off from a diving board.

In an interview for the magazine, Lopez said:

"Until you learn to love yourself, you can’t completely love [someone else] in a way that is pure and true."

We're happy to see that the singer-actress is in such a good place in her life. We wish her and Rodriguez, and anyone who dares take it on, all the best with the 10-day challenge.
