Jennifer Lopez hits the gym before filming for Unstoppable resumes

Jennifer Lopez worked out hard at her second home, also known as Tracy Anderson’s members-only gym, in Studio City on Tuesday.

The 48-year-old celebrity fitness trainer charges $1,500 plus annual fees for VIP access to her gym – according to Town & Country.

The 54-year-old pop star was wearing a maroon blazer from her alma mater — Preston Girls High School in the Bronx — where she ran, did gymnastics, played softball and performed in musicals between 1982 and 1986.

Jennifer paired her vintage jacket with a matching bag, bright leggings, and white Prada sneakers.

Lopez ditched any makeup under huge sunglasses as she worked out, and scraped her natural brown hair into a messy top bun.

In order to maintain her fit 5-foot-5 frame, the two-time Grammy nominee likes to sweat it out “first thing in the morning” and “isn’t afraid to challenge” herself with Anderson and New York-based trainer David Kirsch.

“I’m always evolving and looking for things that keep me excited and motivated,” Jennifer told Us Weekly earlier this year.

“It’s no secret that fitness is a very important part of my life. I believe there is a positive relationship between exercise and mental health. When you find a good balance through determination and focus, we are naturally pushed to be the best version of ourselves.

The sighting of Lopez on the street came on the same day that Artists Equity announced to Deadline that filming on her film Unstoppable would resume starting December 12 — seven months after production was halted due to the WGA strike.

The star producer mom rocked dark hair and arm tattoos on set to portray Judith Robles, the mother of one-legged wrestling champion Anthony Robles, in the directorial debut of Academy Award-winning editor William Goldenberg.

Jharrel Jerome, Don Cheadle, Michael Peña and Bobby Cannavale will also star in Unstoppable – based on the 35-year-old athlete and Austin Murphy’s book of the same name – which will be distributed by Amazon MGM Studios.

Jennifer likely got the role thanks to her fourth husband, two-time Oscar-winning director Ben Affleck, who is producing Unstoppable alongside his Boston best friend, Matt Damon.

“I can’t put into words how proud, excited and blessed I am to not only have my story turned into a movie but to have this movie written by Ben Affleck and Matt Damon is incredible!” Anthony gushed on Instagram back in March.

“So excited for what’s to come!”

Lopez is also promoting her new single, “Can’t Get Enough,” which will be released on January 10.

“Can’t Get Enough” will appear on the Intimissimi global ambassador’s ninth album This Is Me… Now, which is also the name of her show “Musical Experience” which will premiere on February 16 on Amazon Prime Video.

Rock singer Jennifer reunited with director Dave Myers, who previously directed four of her music videos for All I Have, I’m Real, I’m Real (Murder Remix), and I’m Gonna Be Alright between 2001 and 2002.

Lopez reportedly dedicated nine songs to Penn on This Is Me… Now, her first recording since 2014’s AKA.

It’s been over a year since the Emmy-nominated producer wrapped the titular role in the Netflix AI thriller Atlas, and director Brad Peyton just recorded the film’s score at Abbey Road Studios in London in October.

“We had a great time,” Jennifer, who has 392.9 million social media followers, said on Instagram Live.

“This is a beautiful film about the future, but it’s also about letting people in.”

Lopez also serves as executive producer for Joanna Johnson, Bradley Bredeweg, and Peter Page on The Fosters spin-off series Good Trouble, which resumes with Season 5 on January 2 on Freeform.
