The One-Piece That's Basically Required If You're in Tracy Anderson's "TAmily"

The culture around boutique fitness classes, especially in New York City, has become a hot topic in recent years, with one name consistently leading the conversation: Tracy Anderson (TA). Not only does she have a loyal following called the “Tamily” (many of whom invest in exclusive, expensive memberships), but her classes are also known for having waiting lists that fill up within minutes of opening. Beyond the hype and choreography, one detail often goes unspoken, although it’s hard to miss: the catsuit.

If you’ve ever taken a class with Tracy herself (or casually scrolled through her Instagram), you’ve probably noticed her signature look. When she’s not wearing long shorts over leggings (a trend quickly adopted by her community), she’s almost always in a sleek, formfitting workout onesie. It’s more than just a uniform—it’s become a symbol of the TA method.

“I think a lot of the people coming to Tracy Anderson classes definitely want to emulate her style,” says Summer Stewart, a five-year member of the TA community. “And catsuits at TA are definitely a staple. They allow mobility of movement that’s necessary when taking a Tracy Anderson class.”

These performance pieces do more than just support a workout—they sculpt. The second-skin fit smooths and elongates the body, providing a flattering silhouette that feels as good as it looks.

So, is it fashion or function that draws people in? “Honestly, it’s a mixture,” Stewart says. “I love the way a catsuit looks. It feels like a put-together outfit—really without thought.”

That said, when it comes to how Tracy styles her jumpsuits, there’s an undeniable sense of intention—every look feels meticulously curated. She often layers a bolero, cropped graphic tee, or shrug over her sleek onesie, only to toss it aside halfway through the workout. At times, she’ll throw on a pair of Free City sweatshorts for a laid-back edge, and she always completes the look with designer sneakers—think Prada’s Cloudbust Thunder or Gucci’s Wave.

So, if you’re feeling inspired to add one of these ultra-sleek staples to your own athleisure collection, keep scrolling—we’ve rounded up the best workout jumpsuits to shop now.
