A great mix of strength based workouts and cardio focused days in between, I'm able to go 6-7 days a week and never feel repetitive. The coaches are amazing. Many have become good friends over time. I have convinced many area friends to join, but the other members quickly become friends too. Led by Grace, her team is filled with absolute fitness legends. Wallace and Luther run an amazing Lift Club that taught me how to lift heavier with less effort. The knowledge these trainers have is next level. I'm so grateful how F45 has changed my life by making exercise a part of my daily life. Thank you thank you.

Welcoming, thoughtful, and dedicated coaches, team, and owner-- highly recommend…read more Looking in from the outside, the workouts can admittedly feel intimidating at first, especially for non-athletes (like me). But if you can get past the newness and unfamiliarity, the challenge is well worth it. The workouts and community have an engaging sense of camaraderie, structure, and challenge that keeps each session interesting and effective. I have found that by challenging myself in this way, my confidence to face challenges has expanded into areas outside of workouts as well. There is no pressure to join, which I appreciated, and no obligation to socialize (though opportunities are there if you want them). The studio offers a sense of community with familiar, friendly faces that makes workouts accessible and, frankly, fun. I have been going for about 6+ months and befriended kettlebells, sleds, and Ski and RowERGs-- and have seen significant improvements in strength and energy. It has been a great complement to yoga and Pilates. The variation in daily workouts (resistance training, cardio, and hybrid days), which are easy to preview on the app ahead of time, paired with upbeat music--and often a DJ on Saturdays-- makes the time go by quickly. Being able to track progress using their InBody scan has also been a key motivator. The space is bright, modern, clean, and sunlit with large windows. Most importantly, the coaches and team are attentive. They are encouraging and supportive throughout the process. I have been to other F45 locations in other states and can confidently say that the coaches at this location are truly excellent-- professional, friendly, and genuinely helpful.

This makes it so easy to join and finish a workout. The workout average 40 minutes, 4 stations, with 3 sets. There's even a little warm up section, too. Monday and Thursday are lower body strength, Tuesday and Friday are upper body strength, Wednesday is conditioning, and Saturday/Sunday are hybrid/full body. Emilio is a great coach and is always there to correct your form.

Over the past seven years, as I've moved to different neighborhoods, I've been to five F45 studios…read morein Brooklyn and Manhattan, and this was by far my worst experience. It's too bad because the facility is excellent and the trainers are fine, but all other F45 gyms have passionate owners and support staff who genuinely want you to succeed. This one was all about taking your money. On top of that, they do a sloppy job, double-charging for weekly passes and fees. What finally turned me away for good was after dealing with Yuliya over email and the phone to try to correct a double billing mistake. She was abrasive, defensive, and rude (at best) even though she had obviously made a mistake. Horrible customer service. If you are trying to decide between F45 studios, look at any of the other three in Brooklyn. It's worth a short commute to avoid this one.

When I saw that a lot of these reviews were from some 6 years ago, I decided to write one of my own…read morethat reflects the experience they help create today. I joined at New Year's 2025. I was looking for a high-intensity workout experience. Well, I found it! Kim and Luke are now the owners (or part owners) of this branch. Kim is a fabulous coach as well as Aaron, Gerrit, Sidney (and others I know less well). I find the class experience motivating and fast paced. During the class the coaches go by you as you are doing a particular movement and give you great tips to maximize what you are doing. The exercises accommodate people from all different fitness levels, from novices to people who are seasoned athletes. Here's what's happened to me: I now have lower body fat, much more endurance, better posture and, best of all, I am now sleeping more deeply --- like when I was young. This is all in six weeks' time. And, BTW, I am the oldest person in these classes: in a few weeks I will be 71. I feel decades younger.
