F45 Flatiron always delivers on a great workout, with instructors that are nice, fun, and knowledgeable. I've been going consistently for about a year and it's gotten me in my best shape probably ever - I'm addicted! read more

I tried F45 through their two class free trial. I had trainers Grace and Gareth - they are both extremely nice and helpful! I tried the "All Star", which is a resistance based strength workout. In only 45 mins I felt I had a well-rounded full body strength training, and also burned a good amount of calories. It was a challenging and fun workout! I would love to come back and try their cardio workouts on another day. read more

Loved my experience so far at F45! The trainers are great-- they are energizing and also take the time to walk around and correct everyone's form. The TVs on the screens remind you of the movement so that you can move quickly and keep your heart rate up. Saturday workout was especially fun-- they bring in a DJ to motivate the class through a 27 station workout! read more

If you don't have enough equipment and space, please just limit your class size, or better, don't open a gym. There's constant AV problem too, and the class rely on AV. Again, if you can't have the system figured out, don't be a place depending on it. Ended up in a 3 people group with only 2 set of equipment, the instructor's seemingly "worked out" plan doesn't work at all. Overall, really mediocre workout with insufficient planning. I guess that's how a franchise workout place is like anyway. read more

Really love working out at F45, their fast paced workouts each being different gets the most out of you for the time in the gym. All of the instructors there are helpful and motivating ( there are also monitors of the workouts in case you forget) and the facilities are well kept with plenty of room on their main floor and double the area in their locker rooms downstairs. The only thing I had a problem with was sometime their class gets too packed and you may feel on top of someone, but that may be just me. Great Idea of a gym. read more

Great, intense, 45min workout class. Every day is a different workout routine, cycling through 10-15 exercises for short bursts. Some days focus on cardio, with mainly body weight movements and HIIT. While other days focus on resistance/weight training using dumbells/KBs and medicine balls. The trainers are awesome and there are multiple screens with GIFs explaining how to do each exercise. I would definitely take advantage of the free 2-class offer before it expires. See you there! read more

I love the variety of classes offered, no one class is the same. They are challenging and I'm constantly pushed to my limits. The trainers are great and keep you motivated! There's always an awesome playlist to workout to, which keeps you pumped! read more

It's a great circuit workout. The cardio classes are very challenging, and the strength classes leave a good full-body burn the next day. The instructors are attentive and the class flies by! Definitely recommend this studio! read more

I've only been twice now, but I plan on coming back indefinitely. It's a tough, really challenging workout- but super fun. I love that you get paired up, so your partner is going through all the same pains of you, but you motivate each other! I also love the diversity in the workouts- you and your muscles will never be bored. I highly recommend! Luke & Jeff are great coaches! read more

All it took was one class and I was hooked. Sometimes I go twice a day. I highly recommend F45 to anyone looking to challenge themselves.

Took a 7:30AM 'Romans' class. Great energy and enthusiasm from all the instructors! This class consisted of 3 'pod' areas which each had 3 sets of exercises and once you did each exercise 2x, you rotated pods. The class went by really quickly, but I can already tell I'll be extremely sore tomorrow. This studio is great and I'm excited to try some of the other classes they have to offer! The showers // amenities(towels, shampoos, etc.) they have are really good and clean as well. read more

I'm usually not into HIIT workouts but this was so much more! Both times I've been to F45 I had completely different experiences, both just as great. The trainers are super motivating and the workouts are no joke.. I've already told a few of my friends who also loved the classes. I'll definitely be coming back! read more

My favorite new workout in NYC! The classes are a blast - they get your heart pumping but they go by so quickly. The trainers are all so nice and helpful and the workouts are constantly changing and evolving so you won't get bored! Definitely recommend. read more

Love F45! It's the only workout I've found that I'm actually excited to go to. Never thought I'd be one to "look forward" to going to the gym. But here the energy, the vibe, the coaches are awesome! They all get to know you and are super friendly. It's also fun to workout with other people, you form a little family. The F45 Fit family! But the real reason I like it, besides the fluffy, feel good vibes, is because I see results. I love their mix of workouts. 2 days weights, 3 days cardio, and remaining days a mix. The workouts are great and easy to follow, the timings work with my schedule, and quite frankly I don't want to spend an hour working out. I want effectiveness and efficiency. That's what I get here in the time I'm working out (efficiency, 40 mins), I know I'm doing exactly what is going to burn and produce results (effectiveness). They have screens to follow the movements, so you won't forget what you need to be doing. They have coaches leading and watching, so you can get assistance if you need it. They are hardworking and creative with the workout formats; little repetition but enough to where you get good at what you're doing. I enjoy it and highly recommend it if you're not looking for a personalized 1:1 experience. read more

I have gone to two classes now and they have been amazing. Basically each day they offer a different workout routine so it is constantly new and exciting. Within the workout itself, there are many different movements so you never get bored and the class goes by extremely fast. The exercises are not too complicated but man do they work your muscles. Also the instructors are there fixing your form and being your personal cheerleaders the entire time. The facility is very clean! The locker room amenities are awesome (I love the conditioner and the lotion- super fancy - not cheap stuff like a lot of other gyms). Just remember to bring your own lock! read more

It is new, shiny, and a great workout! The music is on point. I never get bored. Facilities are brand new and clean, and everything looks great. Workouts are tough, but can be modified to be easier. The instructors help you out when needed. They keep saying 45 minutes is all it takes, well me working out for 45 minutes by myself vs one of these classes, is drastically different. Everyone is so incredibly nice, I really don't have a single negative thing to say. read more

As someone who loves group fitness I was somewhat skeptical when I first heard about and decided to try another new fitness studio in NYC but I absolutely LOVE F45! They have a different themed for classes each day (45 in total hence the name). For example I did 'panthers' which included "strength, endurance and combat prowess". The different workout themes keeps it interesting and fun...The classes themselves are based around different stations you rotate around which means the 45mins flies by but you also work really hard! read more

This is one of my favorite places to workout! I was hooked after my first class. The instructors are amazing, super friendly, and always ready to give you feedback. There is so much variety in the circuits that you never get bored and you really get a full body workout! I couldn't recommend this place more if you're looking for awesome instructors and high intensity training. Can't wait for more locations to open up! read more

I'm obsessed with F45. I have gone to the two trial classes and I am hooked! It is an excellent workout and a great intro to strength and interval training. I left both classes feeling like my whole body had been kicked into shape. The moves are hard, but they are quick so you get a great workout without even realizing the time that has gone by. My only complaint it the pricing. They are more expensive even than other comparable (and more popular/established) fitness studios. Ill 100% be back to buy a package when they lower their prices from the AU standard to NYC pricing (already high!). read more

Fantastic workout! The gym is spacious, clean, and lots of natural night. Really enjoyed the variation in my usually cardio only workout routine. Every class left me the perfect amount of sore and motivated to continue with my strength training goals. The trainers are super friendly. They give advice throughout the workout to help with form and are definitely modivational. Already started spreading the word and convinced a few friends to check it out! read more

F45 is the best all round workout I've done in the city. A constant variety of classes each week that keeps your body guessing and as it only takes 45mins there's no excuse not to show up each day and just knock it out. read more

Good, solid, well-priced workouts. Not quite the finesse of Barry's etc (strip lighting!) but the actual workout is great and the monthly unlimited is a bargain read more

F45 Flatiron is great! The workouts are very challenging, but fun at the same time and the classes fly by. The circuits make you want to keep going and the atmosphere is extremely encouraging. The instructors are friendly and knowledgable and push you to work your hardest! I love it here and would highly recommend it. read more

I loved F45. The trainers are so helpful and really good at keeping you motivated. I've never had a workout this efficient. The workouts vary in focus of cardio or strength building each day which ensures you are working on all muscle groups. read more

The classes at F45 are awesome. I've taken the two introductory classes and they were fun and challenging. The instructors were extremely motivating and friendly! I don't think I've ever sweat that much in my life. They have locker rooms (with showers) downstairs which are kept clean with great products available to use. Would definitely recommend! read more

New found love for this class! Trainers are always encouraging and helpful. I feel as if I have a personal trainer while working out with a motivating team! I'm always sore (in a good way) the next days after working my butt off at a strength or cardio class. Looking forward to looking awesome in 2019. read more

Best workout and team in the area. All the trainers are great and everyone makes you feel welcomed, without being pretentious. Expect to get sweaty! read more

I had a fairly rocky start with this group - with customer service that could have been better in the beginning. I recently got injured and was unable to use my classes. They emailed me (after my fairly scathing review here) that they will give me a refund. They definitely upped their customer service game - so I am updating my review! read more

i found out about f45 from friends living abroad. tried 2 classes through the trial and loved it! its most definitely challenging and apparently the work outs change day to day. i love how the workouts are shown on a tv screen with the actual movements animated so you'll never forget what the next move is! the instructors are also super friendly and assist you when needed! read more

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! read more

Great HIIT and functional training workouts - I came for a free trial, trying to add more weight training to my workout routines, and was impressed by the variety of workouts offered, and by how helpful the instructors were. I look forward to continuing to work out here! read more

This is a great class. Very efficient and I'm always sore for days after the resistance days. Class goes by very quickly. Can't wait to try a cardio day. read more

I went to F45 Flatiron this morning for the "All Star" cardio class and had a really great experience. The staff was very warm and welcoming and the workout really kicked my butt! It went by super fast too, which is always a huge plus. The locker rooms downstairs are awesome and also a huge plus. I will definitely be back!!! read more

F45 is an amazing workout!! As a runner, I'm always looking for "total body workouts" that actually work my whole body (because we know most of them don't). Since I spend most of my workout time getting in my mileage, I really want my cross training to give me the most for my time. F45 leaves every part of my body sore the next day! I also love that there are TV screens at each station demonstrating the exercise so that once you start the workout you don't have to stop a million times for things to be explained. read more

Great classes, great trainers, great location! Loved it! I'd recommend this to anyone, especially ex athletes.

I just took my first 2 classes and absolutely loved it! I typically go to Barry's 3-4 times a week and mix it up with cycling and pilates but this class kicked my a** like no other and both days felt very challenging and different. The variety of the workouts also makes the class go by very quickly. The instructors are friendly and fix your form throughout to make sure you are doing the exercised properly. read more

Good HIIT style classes and friendly informative staff. Love that the workouts are about 30 minutes and I'm in and out in 45 minutes- love efficient workouts! Wish it was a little more affordable!! read more

great quick workout, the class flies by and it's constantly changing so you never do the same workout twice. in contrast to other f45 gyms the coaches could provide more instruction during the workouts however all are very motivational. would highly recommend the saturday class which is a hour (vs 45 minutes the rest of the week) and and mixed cardio and resistance training, this is the best class of the week in my opinion and the gym usually has a dj playing music during it read more

This workout is absolutely amazing!!! I loved doing their 2 week trial. I am the type of person who doesn't like working out not because I can't but because I find it boring - but I never once found this boring. The only thing for me is the price. It's way too expensive for me - not that that's out of the ordinary with boutique exercise studios. Hopefully one day I'll make enough to justify paying for the membership. read more
