Tracy Anderson is one lucky lady. The celebrity trainer arrived in Miami Beach at the perfect time — right before Winter Storm Jonas.

Adding to Anderson’s good fortune: the petite, ripped 40-year-old left with a spanking new car, courtesy of Buick.

“I do very few endorsements,” said the wellness pro from Prime Fish restaurant in South Beach last week. “I have a strong relationship with my audience whom I care very much about.”

The Detroit-based automobile company chose the blond beauty as its ambassador for the Cascada, a super cute convertible that should hit local showrooms this week. You’ll also see the speedster in motion during the Super Bowl Feb. 7 in a spot featuring New York Giants wide receiver Odell Beckham Jr. and actress Emily Ratajkowski.

“It’s functional but also fashionable,” said Anderson, who drove a Chrysler Le Baron while in high school in Indiana. “It’s not exactly trendy, but it’s a smart car, it just makes sense. And I was shocked at the price [starting at around $33,000].”

Anderson — who has helped shape the bodies of Jennifer Lopez, Madonna and Gwyneth Paltrow, among others — was also in town doing what she does best: leading workout classes throughout the weekend at the Miami Beach Edition Hotel.

But just because she has made the Material Girl sweat, there’s no reason to be intimidated.

If you attend a Tracy Anderson class (a studio is opening soon, she says) or watch one of her educational DVDs, be assured of one thing: There will be no yelling.

“I don’t scream or judge or talk down to you,” said the single mother of two of her exercise philosophy called The Method. “I don’t ask you to push a car up a hill. I’ll put on a great playlist so you can connect to yourself emotionally and we’ll put in the work.”

A typical Method class involves oodles of repetitions to “exhaust your muscles,” with weights no heavier than three pounds.

“It’s about strategy and empowering you, not torture.”

For Anderson, extreme fitness was in her DNA — her late mother was a ballerina: “She was hellbent on making me comfortable moving my body,” said Anderson, who doesn’t share her metabolism. “I love food. If I don’t work out once a day I’ll gain a pound.”

Anderson staunchly believes if you want to achieve the physique of your dreams, stay away from the fashion mags.

“I’m allergic to women saying, ‘I want to look like that celebrity or that model,’” complained Anderson. “It’s so irrelevant and literally the most toxic thing in our society. That’s my biggest fight, helping you achieve your most whole, complete self.”
