Fit Thereom ‐Harlem. ✅️ I am sooooo disappointed that the location is changing. I hope the new location comes quickly and is convenient to get to. Came so far in my fitness journey, don't want to lose momentum.

Huge shoutout to Mateo for an amazing Kickboxing session! 🔥 It’s no secret that you get incredible value (and then some!) when you train with him! I loved his detailed approach, creativity, and good sense of humor—it made the session a blast!The FtO staff truly knows how to bring the right people together, and it certainly shines through in all the sessions I've attended and heard about from others. Plus, that music selection was on point! 🎶‘ppreciate you!💪

I was rehabbing multiple injuries, and then joined FitTheorem a little over a month ago. In a short time, the trainers/instructors/classes have helped "coalesce" my rehab, while improving strength, conditioning, and technique.Great vibes with both the trainers and other participants. The trainers are very attentive and knowledgeable. I've been taking mostly kettlebell + conditioning and kickboxing classes. I would love to join their regular running club as well, but I'm at work at that time. But there's a running route near me.Trainers/instructors/coaches (idk which title's right) are active during classes, correcting participants' forms, giving tips, and pushing us for progress. There were even a few things I noticed only because I'm an overthinker, small decisions that massively targeted trouble areas - thank you. Shout out to all the trainers, who I won't use their government on a Google review, but ya'll know who you are - Thank you, you all deserve raises for your amazing work.

I really enjoy all of the classes here, the instructors are knowledgeable and really help me with my form and technique. The classes are intimate which is helpful and I like how all of the kickboxing sets build off of the previous one so it's easy to learn. Would definitely recommend to those interested in kickboxing!

Very friendly staff who really look after you; very nice team mates and clean too.

2025-06-16T20:10:10.512Z

I can’t speak highly enough of this business, the staff and the incredible instructors. Anyone at any level would be comfortable as the staff is knowledge and committed to you having the best wellness experience and workout.

Great workouts led by knowledgeable coaches. The facility is clean and offers a wide variety of equipment and training options. There’s always something new to try, which keeps things fresh. I’d definitely recommend checking it out!

I’ve only been coming to this gym for a couple of weeks, but I already love it. What stands out most is the sense of community and a relaxed vibe - it feels personal and welcoming, not like one of those huge, impersonal gyms where you just get lost in the crowd. The instructors are great - they take their work seriously and clearly know their stuff, but they’re also super supportive and approachable. I always get a solid workout and it's the kind of place that makes me want to keep coming back. I didn't know I love kickboxing!

Love the studio.It’s my regular work out place.Classes are very good and so are the instructors!

2025-04-04T18:29:29.000Z

Enjoyin thekickboxing very much and appreciating the attentiveness! Special shoutout to Ambi and Ting for their incredible support. Making the trip from Queens to Harlem on electric scooter worth it.

Loving the kickboxing classes even though it is brand new to me. And truly appreciating the attentiveness! Special shoutout to Ambi and Ting for their incredible support. Making the trip from Queens to Harlem on my electric scooter is totally worth it for the exceptional service!

Really enjoying all the options at Fit Theorem, they have a nice selection of classes with different focuses and a staff of really knowledgeable and kind instructors. 10/10 recommend!!

2025-03-12T14:46:05.265Z

Amazing - from the coaches, to the global energy and the playlists. Always the best of part of the day when you get the chance to start it with a kick boxing class at Fit Theorem.

2025-02-28T23:17:30.757Z

A very good place to train, learn and release all your daily stress. Fit Theorem Haroem has very good staff and all highly trained in each of their specialties.

2023-10-24T15:47:02.000Z

I have been a member since 2017 and absolutely love Fit Theorem (formerly ILKB) Harlem. The classes are challenging and fun. But the very best part is all the instructors and fellow kickboxers. It's a fantastic, kind, and supportive community. I always leave class with a full heart and lots of energy.

2023-08-09T01:19:40.000Z

Fit Theorem - Harlem is THE place to exercise in Harlem. The workouts are dynamic, they make you sweat, and get you stronger. But more importantly, the staff that runs the gym are kind, caring and always keep each person's personal fitness goals in mind. I highly recommend joining up to improve your fitness, plus you'll have fun doing it.🔥💪🏾✊🏾

2023-08-01T23:56:09.000Z

Workout variety. We almost never do the same thing twice, so our muscles don't have time to get used to one thing. The instructors challenge us to do better and do more and not to quit on ourselves.

2022-08-08T08:40:41.000Z

Highly Recommend kickboxing !

2022-02-14T14:30:18.000Z

I absolutely love this place The highly skilled instructors will keep you on your toes Get the results your looking for with these workouts

2021-08-24T12:04:57.000Z

Started the 6-week challenge and have noticed immediate results after the first week. 💪🏾 Posture improvement, more energy throughout the day, and feeling stronger.

2021-08-13T19:00:40.000Z

A shoutout to Fit Theorem Harlem. I have loved every one of my workouts there during my summer in New York City. The studio, the trainers (Darryl, Dainer, Bella) and the vibe are all amazing. You walk out a different person! Bella, you’re a star 🌟!!! Thank you for making each session different, challenging yet so much fun. I will miss you. 😘 Thank you for being such an enjoyable part of my NYC experience. See you next year. Natalie

2021-07-08T13:00:54.000Z

I love working out there! The instructors are very knowledgeable and friendly

2021-06-11T03:40:12.000Z

AMAZING OVER ALL FULL BODY WORKOUT AND THE TRAINERS ARE AMAZING AND VERY INFORMATIVE..

2020-02-06T12:55:19.000Z

I HIGHLY recommend ILoveKickboxing. The instructors really challenge you, but will also teach you, and will truly give you a run for your money. I love leaving class feeling accomplished and sweating!

2020-01-13T22:05:02.000Z

The instructors guide you through working out, and are sensitive to everyone's needs. The classes cause you to develop discipline, while also giving you the timeframe to achieve your goals. All of the instructors know my name, and when I am not in class for a week, they make an effort to reach out to me. This location is a gem!

2019-10-29T12:55:17.000Z

I’ve always wanted to join the class so I finally did in April. My body is stronger, I’m more confident and I lost weight. I highly recommend the class. In the beginning it was a little hard, but the instructors are wonderful. They can modify any exercise and you can work at your own pace. You need to join @ilovekickboxing now, because “Summer bodies “are made in the “Winter”!

2019-07-31T21:44:49.000Z

A great full-body workout! But if you are not a member, you will get second class treatment, just a warning to those who are on the edge about purchasing a Group On.
