Fantastic experience: I started F45 two weeks ago and I love it! The programs are clear, focused, and impactful! The trainers are terrific at explaining everything, and it’s not stressful or disorienting to just start! I encourage everyone to give it a try!

Fantastic experience: I always have a great workout here, and always leave feeling a thousand times better than when I came in. The instructors/staff are AMAZING: very friendly, professional, and knowledgeable. The location is always clean, with a stack of fresh towels (which I appreciate because I go through 2 towels every class), and very well ventilated. I don't feel crowded when I work out, and everyone who comes to the class are very nice as well. I've been to many other private gyms - more expensive gyms/fitness centers, and hands down F45 has the best workout moves, technical instructors, one-on-one attention for the price I pay. The Flatiron location is really awesome - if I live in NY full time I would sign up for membership at this location, for sure. Their weekly rate, though not cheap, is totally worth every penny if you want a satisfying total body workout in a friendly, non-intimidating, clean, and professional environment. All of the instructors are really wonderful - but a special shout out to Genna, Sydney, and Emily whose class I regularly attend because of my schedule. You ladies rock. Thank you!

Fantastic experience: I signed up to the F45 one-week try-out at the Flatiron studio, thinking that I would probably like it... but not love it. I was totally wrong - I am OBSESSED. The workouts are very effective, the teachers are extremely friendly and helpful, and the environment is high energy and fun. In one month, I can already see real results - I feel/look stronger, I sleep better, and my body craves healthier foods!

Amanda Wai 3 years ago

Fantastic experience: Clean, spacious F45 studio central to many surrounding neighborhoods. Workouts will get your heart racing at an intensity that’s hard to replicate at home! Special shout-out to head coaches Brendan and Michael for making F45 Flatiron a welcoming space for everyone!

Snigdha Budhiraja 3 years ago

Fantastic experience: Thankyou F45 flatiron for the outstanding live sessions each day. I have thoroughly enjoyed each of my sessions with all of ur talented coaches Michael corrine Phillip Bonnie Kim Elaine Jess brenton. Their attention to detail and providing progressions and regressions each day definitely kept me on my toes. It has been a pleasure and privilege and I hope to see u all in the studio soon. Love and regards from Ashburn va

Varun Aggarwal 3 years ago

Fantastic experience: Have really enjoyed F45 and the instructors at this location in particular. Classes are both rigorous and unique (i.e. things you couldn't / wouldn't get at your standard gym), and constant movement makes them go by quickly. Would consider them much more of a cardio workout vs. strength training, but recommend for anyone looking for HIIT / cardio workouts.

Megan Tigani 3 years ago

Fantastic experience: Great place to workout! Instructors are helpful and encouraging. Workout changes daily with focuses on both strength and cardio

Brandon Trentham 3 years ago

Fantastic experience: Positive: Communication , Professionalism , Quality Today was my first time working out in 9 months after a surgery and wow was it great! Super helpful instructors with the best attitude. I've never been a class person until now and I look forward to my next one!

Cariel Cohen 3 years ago

Fantastic experience: Excellent F45 location with all the standard amazing training + a secret weapon called Michael, best F45 trainer ever. Highly recommended.

Isabella Malaga 3 years ago

Fantastic experience: I have never been one to look forward to a workout until I joined F45! The instructors are inclusive, challenging, and all have amazing energy. Every morning is a new, fun workout that pushes my limits.

Dion Cheng 4 years ago

Fantastic experience: Positive: Communication , Professionalism , Quality I absolutely love attending workout classes at F45 Flatiron. The studio is very clean and well-maintained. All the trainers and staff are very friendly and welcoming. They all have great energy, and are very attentive and motivating. Most importantly, the classes are fun and challenging. I highly recommend this studio!

Pooja Patel 4 years ago

Fantastic experience: Love F45 and all the instructors at Flatiron. The sessions fly by quickly as each class is different, and I love how there are so many different exercises in each class too. After just two weeks of going I felt my endurance and strength start to increase! The instructors are awesome too and pay attention to your form while also challenging you in the right ways. So happy I joined!

Lance P 5 years ago

Fantastic experience: At F45 Flatiron I had the best workout of my life! Highly recommend this place to get consistent intense workouts from friendly staff. The place is small, but they are extremely efficient with their space and you don’t feel cramped. It was easy to follow all the different workouts as they have videos on screens showing how to do each one. They also have bathrooms and showers downstairs which have always been spotless each time I’ve visited. Highly recommend!

Jennifer Haack 5 years ago

Fantastic experience: Love F45 in general and this location in Flatiron is solid. The trainers are super nice with a positive and motivating vibe. They also watch closely to ensure everyone’s form is on point. The location also has clean shower facilities, so you can drop in before work. The schedule of classes seems to be more extensive than the LES one, so more options to choose from. Will definitely go back when I’m back in town.

Ben Mims 5 years ago

Fantastic experience: The facilities are super clean and organized, just like the workouts. The trainers are all helpful and knowledgable and make working out as pleasurable as possible. Great workouts that maximize your time in the class and give me the best workout for my money. Highly recommend F45 over any other gym brand out there now.

Patricia Loviglio 6 years ago

Fantastic experience: The concept of F45 as a training method and workout is great in itself, but the team at Flatiron is what takes it to the next level. Awesome trainers, great atmosphere, and really great community amongst the members. Makes working out at 7am something to look forward to. Love the 8 week challenges, keeps me accountable for getting my workouts in consistently.

G Fernández 6 years ago

Fantastic experience: Great gym and amazing classes. Staff is very motivating and they keep you working continuously. Note that this is not a normal gym. Here they ONLY offer classes to work out during 45 mins in different stations. You prepaid and then book in advance. They used to offer 2 free classes so you could try on. Recommended.

Carolina Araujo 6 years ago

Fantastic experience: Absolutely love the class today! As a personal trainer Im super picky with where I take classes and the instructors I like. I ABSOLUTELY loved and recommend F45 training. The workout was challenging, and I left feeling like I gave 110% because of the motivating atmosphere in the studio! Great job!!

Jasmine Muniz-Cadorette 6 years ago

Fantastic experience: As an ex-athlete turned office worker (having a REALLY hard time adjusting to the sedentary lifestyle), I really missed workouts that focused on moving your body better, getting stronger, and working on explosiveness all the while getting that heart rate going. I've jumped around different studios to find something that combined functional/mobility and strength training along with cardio, and I'm happy to report that this is my last stop! One week in and couldn't be happier with the classes- from the workouts themselves, to the instructors, music and facility! Awesome- you won't be disappointed!

Allison Wallace 7 years ago

Fantastic experience: I recently tried out a couple of classes at this F45 Training location. The instructors are really great. They are very engaged throughout the class and continuously provide assistance and tips on the correct form for a move. They are also really friendly. I like how F45 mixes up the class with a variety of stations so that you never get bored and are constantly moving. It makes the time pass by quick!

Nicole Thurlow 7 years ago

Fantastic experience: One of the best workouts I've ever experienced. The coaches are all super helpful and not pushy at all to get you to join. Would highly recommend and will definitely be going back to try some of the other classes!

Maya Koenig-Dzialowski 7 years ago

Fantastic experience: I have really liked working out at F45. As a triathlete, I love incorporating strength and resistance training. The workouts here are innovative and fun yet challenging. Plus, the instructors are warm and welcoming!

Matthew Jennings 7 years ago

Fantastic experience: I love the energy at F45. The trainers are great at pushing you to your best potential. They help you get your form correct while still encouraging you to the next level of your personal best performance. While the trainers are great, it's the facility that has the best features. The TV screens breaking down the movements with their animated GIFs of each exercise are extremely helpful. Highly recommend to anyone looking to get in shape and learn some functional & important movements. Get your sweat on!

Kathryn Murtagh 7 years ago

Fantastic experience: Great class! The instructors take the time to go through the exercises and make sure you're doing them right. It's fun and fast and provides an all over work-out. I highly recommend.

Katherine Tate 7 years ago

Fantastic experience: The classes are challenging and exciting. I left on an endorphin high. The instructors are enthusiastic abc keep you motivated to push through the workout. They correct your form to keep you safe, but they are always positive. I love the variety of the classes!

Amanda Fishman Redlus 7 years ago

Fantastic experience: F45 is a great circuit workout! Both the trainers and the class attendees are super nice and friendly. There is definitely a warm, team-building vibe about the class. It is also great that they have different class formats each with a different focus (for example a cardio day vs. a strength day.) Gareth was a great trainer, super friendly and informative. I will definitely be returning for more classes in the future.

Sinnifer Sim 7 years ago

Fantastic experience: I hate exercise but I love this place! They change up their routines a lot so you never get bored. There's more than one trainer per class so there's always someone motivating and encouraging you. They go through each exercise before the beginning of class but if you have terrible memory like I do, they have monitors along the wall to show you how to do each exercise. If you have an injury or are struggling with a particular exercise they are always ready with a modification.

Christina Kim 7 years ago

Fantastic experience: Loved F45 so much! Instructors were really attentive and the overall workout goes by super quick because you're moving so fast. I would definitely recommend it to anyone who's looking for a fun and rewarding workout. I can't wait to go back:)

Samantha Sebastian 7 years ago

Fantastic experience: I did the two free classes on Monday and Tuesday this week and am already addicted! The instructors are so motivating and are always making sure you are doing everything correctly so as to prevent injury. My favorite part about it is that alternating days focus on cardio and then resistance training. They're both such different, but amazing, workouts. For me, 45 minutes is the perfect amount of time especially since you are working so hard. It goes by quick due to the circuits nature of the class which I absolutely love. It's like having my own personal trainer! Highly HIGHLY recommend to anyone looking for the workout they've been missing in their lives!

Elena Rogers 7 years ago

Fantastic experience: Great workout! I took a cardio class and a resistance based class and loved them both! You will not be disappointed. The women's locker room was also very clean and easy to get ready in before work.

Natalie Blauvelt 7 years ago

Fantastic experience: This is one of the hardest workouts in NYC...in the absolute best way possible! When I came for my first class, I arrived early while the prior class was still in session. Looking like a lost puppy, one of the instructors left the class to come introduce herself and make sure I knew what was going on, which left a lasting impression instead of an intimidating experience. That welcoming spirit translates through the whole class, with a feeling of being on a team even though your are working solo! The circuit training leaves your breathless and feeling strong, there is such a great variety of classes and exercises. Plus did I mention, LIVE DJ. Music, instructors and other class goers are amazing and keep me going back.

Nakia Gordon 7 years ago

Fantastic experience: Great circuit type workout for beginners or gym junkies, staff are nice and helpful and you can go at your own pace. Definitely felt the workout the next day with my sore muscles! Would definitely recommend.

Sage Sollart 7 years ago

Fantastic experience: F 45 is my new favorite gym!! The resistance classes have been a really great way for me to change up my work out routine and push myself to move out of my cardio comfort zone. The workouts are different every day and my entire body is sore afterwards. They offer all the help and instruction you need, which is really helpful for someone who doesn’t normally lift weights that often. I would definitely recommend, especially for someone who wants to lift but needs some variety and motivation.

Jeanne Low 7 years ago

Fantastic experience: Absolute best workout that I've done in awhile. Instructors are supportive and upbeat. I loved that there are between 2 and 3 instructors for each session, and they were always available to assist or correct posture.

Jessica Lipkin 7 years ago

Fantastic experience: I love F45! I can't wait to go back. I love to do weight training, and this class meets all my needs. It goes by very quick, and I'm never looking at the clock wanting the class to end. I feel strong after! Sometimes in other classes, I feel like they're working us SO hard solely to burn calories, but not to actually help us improve our strength. I highly recommend F45.

Lindsey Schoenberger 7 years ago

Fantastic experience: I very much enjoyed the classes I have taken here. Typically when I work out I get bored very easily. With F45 the quick pace and moving from one movement to the next in short intervals keeps the class moving. It is a great workout that you feel the next day. I would definitely recommend.

Elizabeth Griskova 7 years ago

Fantastic experience: One of the best HIIT classes I have taken in NYC. The workouts are very challenging and ensure that you work all of your body muscles. Instructors are very friendly and offer hands on adjustments to help you do the exercises correctly. Could definitely feel that I have been getting stronger and my endurance has been increasing, very excited to continue the workouts and see how much better I can become!

Lutfi Janania 7 years ago

Fantastic experience: Haven't been to a work out class like this before, it's great! High intensity, short time but extremely efficient. The trainers are awesome, they walk you through each exercise and watching around the members throughout the routine. The studio space is super clean and the machines are brand new. Would recommend 100% It's so good!

Julianne Simson 7 years ago

Fantastic experience: Best fitness experience EVER. I did the 2-week trial here when they first opened, and I instantly became addicted! The only reason I am not there anymore is because I absolutely cannot afford it, which is so sad, because I would be their most dedicated client if it was possible. The two trainers I worked with the most, Garreth and Dina, are not only extremely knowledgeable and helpful, but WOW are they supportive! Every day of my two weeks, I started my mornings here and tried something new, impressed with how I had improved and grown stronger from the day before. Every day and every exercise was unique from the next. They also have a great shower/locker room, fully stocked with everything you need. This is an excellent small business and I could sing of its praises all day - but it's just making me miss these workouts even more! Definitely go - you won't regret becoming a better, stronger YOU!

Irene Vandenberghe 7 years ago

Fantastic experience: F45 is by far my favorite workout that I have done in the city. The instructors are so motivating and really push you to the max. Each class is so different that you will never be bored. The music is great, too! I feel so good after these classes and am so happy this gym made its way to NYC!

heather Buhmann 7 years ago

Fantastic experience: Love it!!! I took two F45 classes and while both quite different, each was awesome in its own way. The instructors I had for the two classes were Grace and Dina. Both ladies were very encouraging and positive. The class challenged me, but since intervals are less than a minute a station, you get to really push yourself. Two thumbs up for format and positivity! You are always welcome at F45 whether your first time or a repeat customer.

Sarah Jane Fay 7 years ago

Fantastic experience: This was my first time experiencing this type of workout, and I was really impressed with how effective it was. The thing I most loved was that the class goes by really fast so you don't get bored, but you still see results! I was sore for about 4 days after my first class! Even though I was new, Luke and the other instructor (don't remember his name), gave me enough guidance that I could jump right in. The facilities and locker rooms are also very nice and well maintained!

Moore Ye 7 years ago

Fantastic experience: F45 is such a great and welcome addition to the boutique fitness scene in NYC. I was able to try two classes for free through their promotion. While intimidating at first (especially if you're not used to HIIT workouts and using a lot of equipment in your workouts), the instructors do a great job at explaining and also demoing each move. I thought the setup of the circuits was extremely helpful (they have screens in the front of each station to guide you in case you don't know how to do the move). The instructor are constantly helping to adjust you and make sure you're doing the move correctly. You will definitely feel the workout the next day, and I do think it's one of the most effective HIIT workouts I've done. The studio also has locker rooms downstairs (but you'll need to bring your own lock), showers, and is a pretty nice facility overall.

Melanie Blanco 7 years ago

Fantastic experience: I absolutely LOVE F45 Training, particularly the weight training / resistance class! The fast-paced nature of the class really helps you push yourself to the limit with each exercise -- trust me, you'll feel it the next day. The trainers are also so encouraging and helpful, and not at all pushy to make you buy a package which I appreciate. I definitely plan to make F45 a regular part of my workout rotation.

Tova Joseph 7 years ago

Fantastic experience: Great small group fitness class! The instructor was friendly and welcoming! He explained all the exercises and really paid attention to everyone and corrected form. It was a great functional training class and really worked out all my muscles!! I'll be back F45!

Estefania Bruzzone 7 years ago

Fantastic experience: This place is fantastic. The work outs were amazing you definitely break a sweat and you feel so energized after the class. I also really enjoyed the instructors, they are super friendly and extremely welcoming. I have spread the word about this place to all my friends, because I loved it that much.
