Australia-based F45 is currently the world’s fastest-growing functional training network, with 750 franchises in 26 countries globally. They opened their first location in New York in April 2017, and the studio has had a fair amount of buzz since, with members claiming to have achieved drastic results in as little as 1-2 weeks. They’ve had so much success here that the franchise openers are expanding to the Lower East Side later this year. So, of course, I had to try it. While I’m not as big a fan as some of its staunchest advocates in the city, I definitely see the appeal and would recommend it to any functional training lover looking for a new fitness home.
