F45 Williamsburg is awesome. The trainers are super friendly and really know how to push you in a good way. The workouts are challenging but never boring, and the vibe in the studio is always energetic. Everyone’s really welcoming, so it feels easy to just show up and get moving. Honestly, it’s the kind of place that makes you actually look forward to working out.

Would leave a lower review if possible. They took me off the waitlist 30 mins before the class so I ran over there and was on time…the door was locked and so I had to wait for them to unlock it (which took 2 mins to get someone’s attention) and then they wouldn’t let me in the class because at that point I was 2 mins late. Ruined my morning. Never coming back.

Can't recommend this gym enough! The energy that the instructors bring creates an environment where you will want to come back. It took me a while to find what works for me but I love the way you can do cardio & strength. Plus, I never get bored since the workout changes everyday. The studio manager, front desk, and instructors are now people I consider friends and can't wait to continue going to F45! Thanks team!!!

I absolutely love F45! From the moment I joined, I felt welcomed and supported. The instructors are not only knowledgeable but also incredibly friendly, helpful, and genuinely caring. They take the time to get to know you, guide you through every workout, and make sure you feel both comfortable and motivated.

What sets this class apart from others I’ve tried is the positive and encouraging environment. Unlike some places where you feel like just another number, here they actually care about your progress and well-being. Every session leaves me feeling stronger, more energized, and excited to come back.

If you're looking for a place that feels like a community and keeps you motivated, this is it!

F45 Williamsburg has really changed my relationship to exercise, being able to just show up and be seamlessly guided through is just a great experience. In just a few months I’ve noticed consistent changes in my body tone and my strength. Best of all I no longer need to go to the chiropractor because my back is feeling better and stronger.

I signed up for the unlimited pass for the month of January, having never done an F45 class before, and this studio has been nothing short of amazing! All of the staff and people are so welcoming and create such a safe and supportive space. I have felt so encouraged to get back into exercising and already feel stronger and healthier having only been attending for a few weeks! I have loved incorporating this into my weekly routine and will definitely continue to attend throughout this new year! Thank you F45 Williamsburg!!! <3

For me, getting up from my desk and going somewhere, especially to work out, is already a big source of stress because I feel like I’m losing valuable time that I could spend doing something useful. However, over the past six months of attending F45 Williamsburg, I’ve started to genuinely enjoy the structure and stability it has brought into my life.

I’m incredibly grateful to all the trainers who constantly motivate us with genuine enthusiasm. They notice and remember every little detail—whether you’ve changed your hair color, painted your nails differently, or are wearing new sneakers. They approach every person with warmth, care, and respect while motivating you to achieve your personal best.

I love the workouts themselves and deeply appreciate how much effort the team puts into ensuring everything is thoughtfully planned. They make sure everyone feels comfortable, that all questions are answered, and that you leave not only having had a great workout but also with a sense of joy.

I’m not typically a fan of making friends at fitness classes; I go to work out, not to socialize. But you can’t escape the sense of community at F45, and I’ve grown to really enjoy it. You realize that you’re not training in isolation but alongside incredible, interesting people, and it’s a pleasure to be part of that.

I’m immensely thankful to every trainer, every staff member who helps with bookings, and the studio owners. My experience at this location has been nothing short of amazing, and I attend with great joy, taking full advantage of the unlimited membership every week—even when I feel like I don’t have the time.

Even during the workouts, when I’m often feeling grumpy, I still leave with so much warmth and appreciation to all the people who were there for me that particular day. I can’t recall a single fitness program that I’ve stuck with longer than F45. That’s just how much I love everything about this experience.

I loved my morning coach however, I had noticed on my evening classes I was getting billed no show fees for classes I had actually showed up to. I discussed with the head coach Tara about canceling my membership. I was under the impression she had canceled last I spoke to her. To my findings she hadn’t in fact canceled it and I was still getting billed the $69 a week. Please watch your bank account. I’ve had to contact my bank about fraud and dispute the charge since they didn’t want to cancel my membership AFTER my 3 month contract of it was up and they had agreed to go ahead and cancel it. Extremely disappointed in this entire process and the lack of professionalism other F45s have.

I initially started coming here because of the first timer deal and was bought into the F45 style workouts after that week. I love coming here 2-3 times a week now for the circuit trainings. You’ll walk into a new workout each time you come in; workouts are unique to the day of the week. The instructors are super energetic, attentive, and instructive with form. The music selection and atmosphere will keep you pumped throughout the workouts, and you’ll walk out of the F45 workouts feeling strong and you’ll be glad you went in that day! 10/10 recommend WillyB’s F45!

Been coming here for about 9 months. Wonderful coaches and great programming. I (39M) was looking for a class environment for motivation and also looking to get back into it after recovering from a couple of years of health issues. Perfect for former CrossFit types that are looking for lower impact and longevity. It is Williamsburg, so the community tends to stay quiet and keep to themselves, but if you’re consistently friendly and encouraging of others, you can build connections.

I really love the workouts in this gym and trainers. My body is definitely reaping benefits. I chose F45 because I realized I spent too much time at regular gyms taking too many breaks and being confused about workouts. Only complaint is I just wish the gym was a bit more social. Everyone is in and out. They have planned a few upcoming events but outside of that people keep to themselves. I thought it'd be like the photos where everyone knew each other. Other than that f45 is great. Still way better than working out alone. The music is awesome. The trainers are great. They help me with form and are approachable. Also, there's no shaming in modifying your workouts. You know your body best. I definitely see myself here for the longterm unless there's someplace better 😅 definitely give it a go if you can afford it. My body feels great. 3-4x a week is sufficient.

Highly recommend!!! I’ve been to F45 gyms in other cities and this is by far the best.

Great workouts with a very strong culture (lots of laughter and personal attention during the workout). Perfect for anyone looking for a sweat! I’ll be back soon :)

This F45 location is amazing. Ps. If you are trying to figure out how to get fit, lose weight and keep it that way… or if you are an athlete, either way, don’t waste any more money or time on gym memberships that don’t and can’t really help you. Get an unlimited membership here and come as much as you can. The programming and personal training is not only included, it’s integral - and it isn’t a gimmick…You’ll reach your goals and the team here will really help you get there. This is HANDS down the most affordable and practical way to actually get to where you want to be.

Chris and Tara are the absolute best. By far the most knowledgeable trainers I’ve ever trained with - consistently sharing 1-on-1 tips for achieving your fitness goals. The local F45 community is another key reason why this studio is better than any other - a great group of people all getting together (COVID notwithstanding) to humbly better themselves. They also managed to immediately pivot in the wake of Coronavirus to offer online classes and outdoor bootcamps. Highly recommend.

Fun joint for some efficient training. I love the format; there are 2 coaches per class and they give great tips while keeping a watchful eye on everyone.

There are two bathrooms, each with Malin + Goetz products, showers and towels available. For the women, there are also feminine products provided.

If you're in the neighborhood come check it out. There's a 7-day free trial going on right now.
