Jennifer LopezandAlex Rodriguezaren’t about to start slacking on their fitness goals anytime soon!

Over the weekend, the retired MLB star, 43, posted a video on hisYouTube account— sweetly set to his fiancée’s hit song “Dinero” — that showed the newly engaged couple sweating it out together during a handful ofintense workouts.

“Alright, day No. 3 workout. Let’s go,” Rodriguez remarked at the beginning of the video, seemingly referring to their10-day no sugar, no carb challenge, as he and Lopez, 49, left their home and traveled to the gym together.

First up, the pair strapped on a pair of “sweet sweat” suits while they worked out on elliptical and stairmaster machines.

Describing their outfits as “goofy,” Rodriguez explained that the activewear is “supposed tomake us sweat” more.

Explaining why he wasn’t following suit, Rodriguez explained, “I’ve had twohip surgeries.”

“Yeah, but your hips work perfect now,” Lopez replied.

“No they don’t,” he countered.

The pair managed to pack in a little fun time during their sweat sessions. At one point in the video, Lopezshowed off her dance movesas her husband-to-be laughed while attempting to follow along.

“Alright guys so I just got back from the gym. It’s day 10. Day 10! We did it; we’re here! I mean, we still have the rest of the day, but I’m feeling pretty good, like we can finish,” Lopez wrote alongside a celebratory video on her Instagram. “Anybody who has stuck with us through the whole 10-day challenge, congratulations.”

Although she admitted that both she and Rodriguez “have struggled through” the program, she wanted to wait for a “few days and then get back on it.”

After finishing the challenge — andhaving an epic feast— Lopezcalled in to theTodayshowand shared that she would “eating normal” for five days before taking on the challenge for a second round.

The singer said she learned “Just how [different] taking sugar out of your diet not only makes you feel, but what it does to your body.”

“I was dreaming about what I was gonna eat, but the truth is you get to a point where you can’t fit that much downafter you remove that much of the carbsbecause that’s really what bloats you and gives you all that inflammation,” she added.
