Back in the summer of 2013, while Jimmy is making his break in the New York City comedy circuit, he takes on a side gig as a personal trainer. During one of his sessions, a client complains about training in the heat (to be fair, it was a scorcher of a morning in July), and remarked on how she felt her fittest and exercised more effectively during the Fall/Winter months. Curious as to how anyone could prefer the cold, Jimmy begins researching the benefits of cooler climate exercise. When he can’t find anything, he knows he’s onto something revolutionary. He comes up with the concept of Brrrn—a cool temperature fitness experience. In May of 2018, they open the world’s first cool temperature fitness studio in Manhattan’s Flatiron/Chelsea neighborhood.
Expanding on their success with in-studio fitness, the team went on to develop a robust "at home" offering focused on a unique slide board (called The Brrrn Board) paired with a streaming on demand video service. The Brrrn At Home online fitness program was launched in 2020 providing thousands of Brrrn fitness fans a new in home experience.
