F45 coaches, gym, and community is amazing! Location super convenient - near the T, a bunch of bus stops, and parking in the square is free before 8am. I started coming after my second kiddo and I've never felt more in shape. Coaches gave been super supportive and I've even found a good friend! Workouts are different everyday and consistent for four weeks, so there's so much variability. Come join us!

I started back when the gym opened and been consistently coming ever since. This gym keeps me motivated with its ever switching and effective workouts. The trainers are super friendly and make it their priority to get to know the members names. Love it here!

I love the community at this gym! I’m new to the area and already this place feels like home. I did the 7 day trial and loved the super engaging challenging work outs plus the energy and feedback from the coaches. I’m now a few weeks into a membership and I cannot stop going, I’m definitely getting my moneys worth. Every session I have received feedback on my form for every exercise and been motivated to up the challenge level when the coaches think I can. Manager/Coach Luca works tirelessly to engage and help everyone while hyping up and building the community. It’s a very fast paced workout but you get the hang of it!

I joined this gym when it had its soft opening last winter. Initially, I hadn’t planned on committing to a membership because I had too many other ongoing activities already, but I ended up changing my mind after attending a few classes. I signed up shortly after and haven’t looked back! The trainers here are awesome and do a great job of correcting your form. They’re also super encouraging and will hand you a heavier weight if they think you can handle it. I love how I can show up in the mornings (either 6:15 or 7:15 if I’ve had a late night) and have a routine already pre-programmed for me instead of spending time pondering what to do at the gym. What keeps me coming back to the gym is the community. No matter where you are in your fitness journey, everyone is supportive and friendly. There are also monthly gym socials and quarterly challenges that help you get to know the members outside of the gym too.

Best place to workout in Cambridge. You can be in and out in 45 minutes, so effective & efficient. Every day they have a different programming (technically you can go every day, but it's pretty intense! Pace yourself). The community is great. Btw, they now have NEW management, and don't worry about cancellations fees, etc, just talk to Luca, she'll sort out everything. She is absolutely customer friendly & helpful. The coaches are all friendly too! Just come over and try it out.

F45 as a paradigm combines many of the best aspects of the fitness industry into a continent and highly efficient package. By focusing on HIIT training with clear demonstrations of movements available at all times, F45 offers its clients aerobic and anaerobic all week in a way that caters to busy professionals who want to become fitter and improve their body composition. In 45 minutes, I personally burn on average 500 calories a workout and as such, I have never found a fitness program that allows me to eat what I want and stay in great shape with such a low time commitment. This particular location is well-maintained by an excellent staff and as of November 2023 is run by the talented and charismatic Luca. Luca not only offers top-notch biomechanical expertise to her clients but works tirelessly to make them everyone happy and manage her staff. I cannot recommend F45 highly enough!

I started at F45 Brattle Street this summer and have absolutely loved it. Not only do I love the variety of workouts and the way I feel after each session, but it’s also extremely evident how tight the community is. All of the coaches make an effort to know everybody by name and it goes a long way. Coach Luca, the studio manager, is especially attentive to everyone. She works around-the-clock to build this community and goes miles out of her way to figure out what works best for each person individually. As soon as you enter the gym, Coach Luca’s impact is evident through the infectious laughs, smiles, confidence, and cameraderie that radiates throughout the room- and I super appreciate that. Looking forward to continuing to push myself with the Brattle Street team!

F45 Brattle is THE BEST community. The instructors are so welcoming and supportive. They are also really good at correcting form to avoid injury and to maximize your workout. I've learned so much from them. Luca (the studio manager) is great. It is clear that she takes a lot of pride in her work and is eager to connect with members. She's helped me break down complicated movements into simpler steps so that my form doesn't suffer. She is also a ball of energy and smiles which is always appreciated.

I’ve tried a lot of gyms and studios in the area in an effort to find one that clicks and keeps my workout routine consistent, but I’m so happy I recently found F45 in Harvard Sq. Luca, Sonia and the team welcomed me in right away and I’ve hit the ground running with my workouts there. I love how efficient the class structure is and being surrounded by a motivated, enthusiastic community at the gym makes a huge difference. I always leave feeling really glad that I made the time to go. Highly recommend!!

I love F45! I work in the square and joined last month because I needed a place I could get to easily during lunch or right after work, and wanted something different than the many yoga and barre places around. F45 has been amazing! The coaches are wonderful and fun, and the class participants are very friendly. I love the bootcamp/personal training vibe in the group class setting. They also have two bathrooms you can change in and a shower. Perfect for workday workouts!
