It’s a stretch for Gov. Cuomo’s sister-in-law to follow the rules on social distancing and mask-wearing.

Cristina Cuomo, wife of the governor’s brother and CNN host Chris Cuomo, posted an Instagram video showing her doing a maskless yoga session just inches from a pal in the East Hamptons Jimmy Choo shoe store.

Both Cuomo and the friend, Erika Halweil, a yoga instructor, removed their masks within seconds of starting the nearly 70-minute workout Wednesday, conducted in front of shelves of pricey stilettos.

Not all viewers offered them namaste.

“Wear masks!” one commented.

“Can all gyms and studios open in NY or just yours?” asked another.

Gov. Cuomo, who regularly urges mask-wearing, including in a tweet Saturday, has refused to allow gyms to operate even when a region reaches the last phase of the state’s four-step reopening process.

Upper West Side gym Momentum Fitness commented on Instagram that Cristina Cuomo, who publishes a magazine called “The Purist,” should use her position as “as an influencer” to help.

“Your health and wellness magazine feeds off of the gym industry and we are all slowly suffocating to death. Please use your power and direct line to the Governor to advocate for small gyms or else we will not be able to support our families as well as help those in our communities. PLEASE HELP US!” the gym commented.

Manhattan pilates studio owner Tara Gordon wrote “If any of us had done that we’d have been fined and potentially lost our business.”

“You have a voice via @thepurist and a direct line to the only person making these decisions to keep us all closed indefinitely. We aren’t hating. We are asking for help,” Gordon wrote.

Cuomo, 50, was diagnosed with COVID-19 in April about two weeks after her husband came down with the bug and quarantined himself in the family’s Southampton basement, where he continued to broadcast his show.

She shared some wacky home remedies for the virus — like taking a bath with a quarter cup of bleach in the water. And Chris Cuomo infamously got into a spat with a bicyclist in the Hamptons who confronted him for going maskless.

Cristina Cuomo did not immediately return a request for comment.
