Solidcore fitness guru snags luxe SoFla condo — before it’s even built

What a flex!

It’s not even built, but fitness guru Anne Mahlum, founder of the cult-favorite workout Solidcore , just signed a contract to buy a massive condo asking $14.6 million at the St. Regis Residences in Sunny Isles, Florida.

The 53rd-floor unit will be in the St. Regis North Tower and is slated for completion in 2029 (its South Tower, meanwhile, will be done by 2027). Mahlum was represented by Chad Carroll of Compass.

“I’m buying it as an investment,” Mahlum told Gimme Shelter. “There’s nothing like it. I think it’s going to be the most beautiful and exclusive building along the Miami coastline.”

And besides, the fitness guru — who married her love, life coach Brett Eaton, earlier this year — added that five years from now, she may also decide to live there with her family.

The sprawling 5,638-square-foot unit will come with four bedrooms and 6½ baths. A designated media room can also serve as a fifth bedroom. The unit opens from a private elevator landing. It features high ceilings and east and west views from two terraces, including one that overlooks the ocean.

Both terraces total 1,060 square feet “so you can see the sun rise and set,” Carroll said. He added that the main bedroom suite, which features a spa-like bath facing the ocean, has a walk-in closet “bigger than most New York City apartments.”

At 750 feet tall, the St. Regis will be South Florida’s tallest residential building on the ocean when completed. It was designed by Arquitectonica with interiors by São Paulo, Brazil-based designer Patricia Anastassiadis, and landscape design by EDSA. In February, a $55 million penthouse in the building’s South Tower also went into contract, as Gimme previously reported .

Both towers sit on 4.7 acres with 435 feet on the ocean. Amenities will include a private beach club, a gym and a wellness center.

The St. Regis condo is Mahlum’s 11th property acquisition in the past nine years. In 2021, she paid $3.6 million for a Casa de Campo villa in the Dominican Republic and sold it to baseball legend Albert Pujols 18 months later for $5.6 million.

The next year, Mahlum paid $8.35 million for a Nolita penthouse at 260 Bowery, which she sold seven months later for $9.75 million. She also worked with Carroll to buy her primary residence in Pinecrest, Fla. —  a 10,000-square-foot home with a pool, a beach volleyball court, a sauna and a cold plunge pool.

Mahlum got her start in 2007, founding the Philadelphia-based non-profit Back on My Feet, a running club for the homeless. After discovering Pilates in 2013, she put her life savings — $175,000 — into launching her own fitness club, Solidcore, which she ultimately sold for $88.4 million.

Now she’s spending time consulting on brick-and-mortar health and wellness concepts, speaking and investing, Mahlum told Gimme.
