NYC residents sue noisy gyms

Trendy fitness routines that involve smashing weights to the ground, blaring techno music and flashing lights are driving New Yorkers who live above city gyms bonkers, according to three new lawsuits.

At the CrossFit on E. 86th Street near York Avenue, a $1 million suit by residents of the building alleges that gym rats are lifting barbells over their heads and then dropping them to the floor in a training regime called “clean and jerk.”

“As might be expected, the sounds and vibrations caused by the incessant impact of the weights travel through the structure of the building … shaking the floors, furniture and windows in the apart units,” residents from the 65-unit co-op gripe in the suit.

The racket is equal to the sound of a train whistle or jackhammer and lasts from 5:30 a.m. to 11 p.m., the court papers claim.

The nearly around-the-clock noises make “ordinary living, reading, studying, relaxing and sleeping in many areas of the building impossible,” the suit says.

But gym owner Debra Frohlich told The Post she’s bent over backwards to be a good neighbor.

“We’ve made major efforts to assure that we’re as quiet as we possibly can be,” said Frohlich.

She said the weight dropping is explicitly barred in the gym and members are penalized if they perform the move that’s popular among CrossFit enthusiasts.

“The penalty is 40 burpees,” Frohlich explained of a dreaded exercise similar to a hybrid push-up.

In the second, $6 million suit, Tribeca residents of a landmark luxury loft condo at 140 Franklin St. fear that a new Crunch branch will mar the building’s family-friendly atmosphere with its trashy exercise lessons.

“The fitness, spinning and pole dancing classes typically offered at the gym, along with the accompanying loud, fast and repetitive music and lights at late night and early morning hours are akin to the atmosphere at a discotheque or bowling lanes,” the historic district loft owners gripe in their suit.

The 13-unit condo complex is home to J.Crew CEO Mickey Drexler, who plunked down more than $13.5 million for a five-bedroom in 2012, and a senior Goldman Sachs executive.

“They’re just really upset,” the residents’ attorney David Pfeffer said in an interview.

“It’s a big problem,” he added, explaining that the owners were told by the developer that retail tenants would exclude discount stores, dry cleaners, delis, massage parlors, clubs and bowling alleys.

But Crunch incorporates many elements from the laundry list of the barred tenants, the suit says.

Crunch has not yet moved in, but Pfeffer said the gym plans to sign a lease for the space this month with the space’s owner, John Calicchio — despite the objections.

Calicchio and Crunch did not immediately return messages seeking comment.

The two suits were filed in Manhattan Supreme Court on Thursday and Friday, respectively.

A third case by a Chelsea condo board against another CrossFit gym began last November and is still being litigated.
