Who Is Leah McSweeney and Tinsley Mortimer's Boxing Trainer? Here's Why He May Look Familiar

You may have asked yourself many questions while watching the May 14 episode of The Real Housewives of New York City. What does Luann de Lesseps really think of Leah McSweeney's apartment? Why do Dorinda Medley and Tinsley Mortimer always seem to be fighting these days? Is that Sonja Morgan going to the bathroom in a corn maze?

However, there is one mystery that stands above the rest: What's the deal with Tinsley's boxing trainer?

We first met Martin in the RHONY Season 12 premiere when Tinsley met up with Leah for some exercise (clip above), and it was clear from the get-go that he is a no-nonsense kind of guy. When Tinsley said she was "losing a little part of myself" by having to take off her hoop earrings before boxing, Martin told her, "Aaaaaaaand, nobody gives a f--k."

Luckily, Tinsley was able to get out some aggression with Martin in the ring. It must have been a good workout because she returned to his gym, Trinity Boxing Club, in the most recent episode of RHONY. Martin gave Tinsley a warm welcome by tossing her a football to her in the street — apparently, something of a signature move for him — and she caught it! Unfortunately, Martin mistakenly called Tinsley "Dinsdale" when he greeted her, a faux pas he would make again during their training session.

Not only did Tinsley get in some physical exercise, but she also got in a mental workout with Martin this time as she opened up to him about everything from her love life to her drama with Dorinda, whom he referred to as "Dorito." "Martin's really not easy to talk to, but he forces you to sort of fight him," Tinsley explained in an interview during the episode. "You know, you're fighting him with your first, and you're fighting him with your words. He really makes me be honest with myself."

Martin delivered some wise words to Tinsley, even calling her a "legend," as they chatted following their training session. "Right now, you live a life of doubt. And what's the antidote to doubt? Faith," he said. "You know what you want, you know what you like. You know, nobody else. Do whatever the f--k you want to do."

Martin also has a fan in Sonja, who agreed with his advice to Tinsley while live tweeting the episode.

And Sonja isn't the only one. It looks like Martin has already become something of an unofficial member of the RHONY squad with some fans even playfully hoping he gets an apple in the future.

It turns out Martin, whose full name is Martin Snow, has been Leah's boxing trainer for many years. Leah can be seen training and hanging out with Martin all over his Instagram, as well as that of Trinity Boxing Club. He's given her a pretty badass nickname, too: the Mighty McSweeney.

Leah recently opened up on Instagram about how much Martin and all of the trainers at Trinity Boxing Club have helped her through the years. "Miss you @martinsnow @trinityboxing. You have gotten me through the most challenging times for the last decade," she shared. "You trained me to fight and to embrace my crazy. Cannot wait to be in the ring again."

Martin is the owner of Trinity Boxing Club. He started boxing at the age of 8 and boxed competitively as an adult before going on to train others, according to his bio on Trinity Boxing Club's website.

The gym itself dates back to more than 100 years ago when Martin's great-grandfather, an Irish prizefighter named Lorenzo Snow, opened a "boxing speakeasy" upon his retirement, calling it the Trinity Club, named after his firstborn daughter. The gym attracted heavyweight champions and notable clients like Jack London, Ernest Hemingway, and Theodore Roosevelt, according to Trinity Boxing Club's website. 

When Lorenzo's wife, Maggie, took over the establishment following his death in 1919, she renamed it the Trinity Boxing Club and operated it as a speakeasy during Prohibition. Al Capone and Charlie Chaplin were just a couple of the famous faces who walked through its doors.

Trinity Boxing Club, which also has a gym in Los Angeles, still has a star-studded list of clientele today. In addition to New York Housewives, Martin has also trained the likes of Kit Harrington, Gwendoline Christie, and Ansel Elgort. Martin has been featured on America's Next Top Model. Ray Donovan filmed also filmed at Trinity Boxing Club, and The Contender held its Season 1 tryouts at the gym with none other than Rocky himself, Sylvester Stallone, and Sugar Ray Leonard, who co-hosted the boxing competition reality series.

When Martin is making boxing superstars out of the New York Housewives, it looks like he's an impressive photographer, as you can also see on his Instagram with his many photos of the Big Apple.
