Jennifer Lopez Reportedly In The Best Shape 'She's Ever Been' Amid Ben Affleck Divorce Rumors

Jennifer Lopez's fitness trainers have opened up about the singer's rigorous routine and strict diet as she continues to flaunt her trimmed-down look on red carpets.

Meanwhile, rumors of marital issues with Ben Affleck have surfaced, with reports claiming the pair is headed for a divorce.

During an appearance on "Live With Kelly and Mark," Lopez revealed that she is the "thinnest" she has ever been and in "fighting shape right now" after an intense workout regimen in preparation for her role in "Kiss Of The Spider Woman."

Sharing insights into her recent project, "Kiss of the Spider Woman," the 54-year-old mentioned: "I just finished [filming] a movie called Kiss of the Spider Woman where it was all singing and dancing, which was equal parts exhilarating and exhausting as well."

The Bronx native has been showing off her toned physique while promoting her sci-fi thriller, "Atlas." She recently appeared in skimpy outfits in Los Angeles and Mexico, which highlighted her figure.

Her trainers, Dodd Romero and Tracy Anderson, also spoke to UsWeekly about how Lopez maintains her impressive shape. Romero noted her dedication: "Jennifer's in better shape now than she's ever been. She's tough [and] really doesn't ever complain about anything. Wherever I tell her to go, she'll go."

Lopez incorporates resistance training into her routine three times a week with her trainer, Romero, and keeps her workouts varied for motivation.

Her regimen includes three sets of hanging ab raises, rope crunches, and weighted sumo-style plié squats.

Romero emphasized that the "Hustlers" actress is mainly focused on toning her glutes, with her favorite exercise being the "supportive lunge."

Additionally, Lopez often visits the Tracy Anderson Method gym in Los Angeles, where she engages in dance aerobics using Anderson's band system.

Anderson shared with Us Weekly that they do a "10-move leg program focusing on the glutes and the cinching of the waist," incorporating leg pulses and box step-ups with 1.5-pound ankle weights. "Moving is part of Jennifer's core values. She does what she needs to do," Anderson noted.

Lopez also maintains a careful diet in her fitness regimen. Her trainer, Romero, noted, "As you get older, you have to be more strict."

The singer avoids sugar and dairy but allows herself occasional indulgences. "If her kids want to have a meal that [isn't] the lowest in calories, Jennifer will have the meal with them. She's not rigid," Romero explained.

"Romero also revealed in a previous interview that Lopez, who abstains from alcohol and caffeine, ensures she drinks at least seven glasses of water daily. She avoids "processed foods and gets her nutrients from whole sources."

In July, "The Mother" actress is set to launch her "This Is Me … Live tour," marking her first tour in five years. This announcement follows her recent appearance in Mexico for the premiere of her sci-fi thriller, "Atlas."

At the Los Angeles premiere of "Atlas," Lopez spoke to Entertainment Tonight about finding comfort in her close relationships. "The one thing you can always trust in is family," she shared.

Coincidentally, Lopez's comments about family come amid swirling rumors of marital issues with her husband, Ben Affleck. According to Page Six, Affleck is ready to end their marriage after two years.

The actor was noticeably absent from his wife's big premiere as he was busy working on the sequel to his film, "The Accountant."

A source told the news outlet that the Oscar award winner has "come to his senses" after waking up from his "fever dream" marriage to Lopez.

Despite their issues, Affleck and Lopez are working hard to push their marriage past this rough patch, and the actor's ex-wife, Jennifer Garner, is reportedly their number one "cheerleader."

A source told the Daily Mail, "JLo and Ben are trying to make this work with all their might, and Jen is definitely a cheerleader for them. Jen and Ben's kids love JLo like a second mom, and it would devastate them for this to end."

In recent days, Garner has been spotted with the couple for events related to their children. Affleck has also been seen without his wedding ring on multiple occasions, which has further fueled the rumors that he and Lopez are headed toward a divorce.
