I've never been fitter than when I've been at F45, even with the virtual workouts. There's a real sense of community/family here and the instructors/trainers absolutely rock. That's the reason I keep coming back. I've tried other F45 studios but the Park Slope location has the best staff by far.

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.

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 am so lucky to have found this place. If your serious about any ANY physical/mental performance…read moregoal. Cedric is THE top. I have watched in awe as my body now: - recovers while doing other physical movements -catches its breath while running - does what my mind tells it to far beyond what I thought I could. (Have literally pushed 5 more reps, by hyper focusing on the muscle even though I couldn't feel it and relaxing all else. I watched myself amazed) Cedric Cosiac has been my physical and mental trainer here for the last six months. He has trained not only my body but my mind, to such an extent that I can accomplish vastly more physically than I ever thought possible for myself. I am writing this because I have just stepped off a high intensity dance shoot involving everything from ballet to acrobatics, parkour, martial arts, hip hop, to a few things we just invented. I was the only person on camera. We were supposed to have two days to film but we only had one and had to race against the clock as the sun was our light source. This means I get little to no breaks in between takes where I am required to dance full out in huge bursts. I was required to stay in muscle fatigue for 12 hours. But I PULLED IT OFF WITH ENERGY TO SPARE ! Why ? Cedric. The active recovery and breath training allowed me to maintain energy and recover while moving. The endurance training we do allowed my muscles to last longer and perform better. (I told him I had to do a high intensity dance piece on film months ago and he designed a routine to match exactly) His overall attention to my mental state during our training allowed me to remain completely calm and slow my heart rate, focus, and not waste energy. Everyone was in awe of what I was able to do. I genuinely wouldn't have been able to pull it off had it now been for our training I used EVERYTHING he taught me and it's just the beginning. He has shown me what I am capable of. I do not know of a greater gift than that.

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.

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.

The instructors have such a unique approach--while they make everything look easy, don't be fooled. You might find yourself complaining. No but seriously, The workouts are challenging and push your body in the best way. Danielle, the owner, has created an environment that is safe, and welcoming for women of all ages and sizes, where everyone is encouraged to go after a healthier lifestyle. One thing that really stood out to me about Danielle is her integrity. From day one, I've noticed that she holds herself to the same standards she asks of her clients. The fairness she applies to her classes, combined with her unwavering commitment to the rules and values, sets the tone for the entire gym community. She leads by example, and it shows. Every class I've attended has been a rewarding experience, and there are so many different types of workouts available to help you continue improving. One byproduct of attending has been the boost in my mood since some days are just rough. I found that moving my body started to help with my mental health. If you're considering taking a class here, I highly recommend it! Yes, it's an investment, but your body is your most valuable asset, and taking care of it is worth every penny. The positive energy from the group of women who attend is also incredibly motivating. If you're looking to start or elevate your fitness journey, this is the place to do it!
