ABSOLUTELY FANTASTIC STUDIO. i enrolled my wife and daughter here for them to have a place to feel comfortable with learning how to become more physically fit. Instead they have brought me with them. And i can’t say thank you enough. Battling multiple work and sports injuries over the years has had me scared to get back in a gym, and now I can go and focus on being healthy instead of being judged. THANK YOU for helping me find my GRIT and determination again!

I’m sharing my experience with GRITT located in Islip (used to be in East Islip) to warn others about their deceptive and unethical billing practices. THE OWNER REFUSES TO PROVIDE ME WITH A COPY OF MY SIGNED CONTRACT - the booking app her studio uses CLEARLY SHOWS I did not sign any agreement with them. This is not how an honest business operates. I have filed a police report, complaints with my bank, the BBB, the FTC and the NY Attorney General’s Consumer Frauds Bureau.
I met the owner, Saraii, in February after trying an intro kickboxing class. I was very upfront that I already had a personal trainer and do private Pilates sessions so I didn’t have the time or money for another program. I was suckered in anyway and gave my card for a month .. 4 sessions .. I was then told they “prefer” a 2–3 month commitment, so I agreed to that short period (12 classes) to support a local small business. They were adding Pilates to the studio so I figured worst case I would have 12 Pilates classes and get to experience a different instructor.
A few weeks later, I realized their schedule really didn’t work for me and texted the owner in March and April telling them that and asking to cancel my account and turn off automatic payments. In the texts I said I would pay for the 3 months. I was responded to so I assumed my account was no longer active. Again, I figured I had 12 classes I paid for and could make use of.
Fast forward to September, I decided to try one of their new Pilates classes, believing I still had a few unused class credits banked from the short commitment I had paid for. After class, I was told I had to download a new app to sign up for their classes moving forward. I was told to put my card info in there so yesterday when I saw my account was charged by them I assumed it was cause of the new app so I texted to have my money refunded. No response, went to class at 4:30 and asked the owner about it who said she was going to get back to me. I then learned once I was home that they had been charging my account every single month since February totaling over $2,000!!! Mind you, I’ve attended fewer than five classes and didn’t go there from February - September but they continued to collect money from me UNAUTHORIZED with no contract.
When I asked for a refund for all the months besides the 3 I “committed to”, I was told I had a “verbal contract” with the owner WHICH IS A LIE and I have to email to cancel, even though I never signed a written agreement and had already texted multiple times to stop payments. Instead of responding to my MULTIPLE TEXTS that the only way to cancel was in the form of email they just kept charging my account. I have now found other people they’ve done this to through social media so this is common business practice for them to STEAL!
Instead of resolving the issue, they now have blocked me on social media and had my reviews removed. They are spamming their Google reviews to bury mine. Notice she replied to all 1 star reviews except the one with proof of the allegations against her and her business? PLEASE DO NOT BE FOOLED BY SARAI.

Sarai literally explains everything — policies, membership terms, refund rules — with clarity. And the policy literally says: if you want to cancel, you text AND follow up with an email. That’s not new info — it’s posted.

Calling her a scam artist is wild. Anyone who’s actually met Sarai knows she’s fair, transparent, and honest. She even posts the contracts AND non-contract options publicly. Who does that if they’re shady?

Let’s be real — you’re upset you got billed for months you didn’t show up, but then you came back and trained. So you used the service, but now want to publicly trash her over it? That’s not just uncool — that’s character assassination

Sarai is very thorough and detailed when she goes over membership and refund policies. If you wanted to cancel, a text message should have been followed up with an email per their policy? I know Sarai and she is very fair and understanding, scam artist is not who she is and all these comments dem people that have never met her would be different if they saw how Sarai interacted with everyone and detailed memberships.

She’s so honest she posted the memberships on the website with and without contracts.

You’re just ruining someone’s livelihood bc you got mad they billed you during months you didn’t come in yet came back to workout later on? Maybe if you don’t smear her character and business across all of Islip, things would have ended differently

From the moment you step inside, you feel seen, supported, and encouraged to grow at your own pace. The place is always clean and equipped .

The coaches lead with honesty and heart. They’re not just here to train you—they’re here to guide you with real feedback, transparency, and commitment to your progress. Every class is filled with purpose and positive energy, making it easy to stay consistent and motivated.

GRITT has helped me find balance, confidence, and a deeper connection to my own health. If you’re looking for a place that genuinely cares and delivers on its word—this is it.

Sarai’s the kind of trainer who genuinely cares about people. She has the knowledge and the experience to help you reach your goals, and she’s always striving to bring out the best in everyone she works with.

She goes out of her way to support active-duty military, law enforcement, first responders, veterans, and local small businesses. Just a solid person who puts her heart and soul into what she does — which, ultimately, means putting her heart and soul into you.

Bad business

This place is a scam and a fraud. They take unauthorized payments from their customers, and ignore written requests to cancel memberships. Sarai has shown no remorse and is completely unwilling to help, which leads me to believe this must be common business practice. There are hundreds of other gyms and fitness centers in the area, if you knew what was good for you you would spend your money elsewhere.

I joined Gritt NY in East Islip at the end of 2022. I’ve always wanted to take a kickboxing class to supplement with my weight lifting routine. Gritt is a family. Sarai is a great owner, instructor and friend. If you are looking for a kickboxing class that kicks your ass in a good way, stop by the studio. I love the kickboxing and HIIT classes. Sarai also offers nutritional counseling.

I’ve been a member at Gritt for almost 3 years and I couldn’t be more impressed with my results. The workouts have helped me build muscle and significantly improve my endurance. The coaches are motivating and knowledgeable. Every workout is challenging but accessible to all fitness levels. If you're looking for a workout that will not only get you in shape but also boost your strength and stamina, I highly recommend becoming a member at Gritt!!

I have been going to Gritt for almost a year now it was one of the best decisions. Sarai is an amazing coach who's very understanding & supportive. A few years ago i had a surgery that left me with no abdomen muscles and I thought I wouldn’t be able to do a sit up ever again but thanks to Sarai helping me rebuild my abdomen muscles i am now able to do sit up again after 5 years. From kickboxing to strength training and nutrition assistance if your looking for a place to start your fitness journey Gritt is the place to do it

Absolutely LOVE GRITT! ♥️ Found this place about 2 years ago when I was looking for a new kickboxing studio as the one I used to go to was too far from my home. I did try one place first (a chain kickboxing studio) and felt so uncomfortable with so many things (from the owner, to the favoritism in classes, etc)—it just felt awkward to be there. After “pulling teeth”, I was able to cancel my membership at that place and went on the hunt again for another studio.

After googling, I found GRITT so I reached out and went to the studio to meet Sarai (the owner). One could tell she has such a passion and care for fitness, Her heart is in her studio and those who come through her doors. I gave GRITT a try and within a day, I got a membership and have been a member since (started in 2023). Sarai and all her instructors are always so welcoming, encouraging, etc. And those who attend the classes are just as warm and kind. Everyone helps one another and encourages each other, which is something I love. The studio itself is clean and there are a bunch of times to choose from for class. They also do so much giving back to the community which I absolutely love too! If you are looking for an encouraging community with a dedicated owner and awesome instructors whose hearts are “all in” to helping you become the best version of yourself, GRITT is your place! Strongly recommend!! 🥊

Gritt Kickboxing Studio is a fantastic boutique fitness space that offers kickboxing and strength training classes designed to energize, challenge, and support everyone, regardless of fitness level. The hour-long classes are thoughtfully structured, beginning with a dynamic warm-up, transitioning into high-energy kickboxing and strength training, and ending with a cool-down and stretching session. The coaches are exceptional—knowledgeable, approachable, and skilled at providing adaptations to ensure every participant feels comfortable and successful.

What truly sets Gritt apart is the community. The welcoming atmosphere fosters connections, and I’ve made many friends here. It’s more than a fitness studio; it’s a supportive space where you can grow physically, mentally, and emotionally.

Additionally, Gritt offers nutrition counseling for those interested in complementing their fitness journey, and they run a remarkable weekend program for young girls focused on building confidence and self-esteem. My daughter has attended this course and loves it—it has been a genuinely uplifting experience for her.

If you’re looking for a place to get fit, feel supported, and become part of a wonderful community, Gritt is the perfect choice!

GRITT Studio is a place where I’ve found a sense of belonging. From the very first class, I felt like I was part of something bigger than just working out. Everyone here, from the trainers to the members, is so supportive and encouraging. It’s like joining a fitness family. For me, it’s been about more than just getting in shape. GRITT has helped me carve out time for myself, something I didn’t realize I needed so much. It’s a space where I can let go of the daily stress, push myself, and actually enjoy working out. The classes are fun and challenging, and the energy in the studio is so contagious. Over time, I’ve noticed not just physical changes but also a boost in my confidence and mindset. If you’re looking for a spot to not only get stronger but also connect with others and feel good about yourself, GRITT is it. I’m so glad I took the leap—this place has truly made fitness fun and fulfilling for me.

If you are looking for a work out that is not only good physically but mentally then GRITT is the place to be. It is a full body workout that works on strength, agility, stamina, and coordination all at once. The energy the studio brings is positive and uplifting and I always leave feeling a lot better than when I walk in. The owner Sarai takes a personal interest in the journey of each of her members which makes it truly a place one feels welcomed and comfortable which is a rare find. I highly recommend GRITT!

Gritt is the place to go! It is not a quick fix but with the coaching from all the trainers and the kickboxing/strength training classes you will reach your goal in no time! The trainers are incredible! They will do what is best for you and only you. Also they aren’t there just for weight loss or toning up, they are also very understanding and attentive to what is happening outside of the studio in your life which could affect your fitness journey so if you feel like having a therapy session (😆) and working to better yourself in all aspects: weight loss, mental strength, emotional strength, tone up, etc well then I highly recommend joining Gritt and be part of this fabulous family!!

I remember when I was searching for a place to start my fitness journey, and being overwhelmed by the choices laid out in front of me. Perhaps it was the color scheme, or Sarai's story, or maybe fate, but I couldn't be more happy with my choice. I'm about 8 months in, and have no regrets. Gritt, Sarai the coach, the atmosphere of the studio, fit me like a glove. If you're reading this and on the fence, allow me to push you to give it a try. "Come As You Are", in neon lights will welcome you at the door (and if your lucky a beautiful dog) and it rings true. Don't deny yourself a safe space, judgment free, to improve your life. <3

I came to Gritt about 5 months ago. Saraii started me out with a “No Sweat Intro” which was a one on one session with her. She took the time to explain the class to me, we did a body scan so she can see where I was at and what I needed help with. I have never had someone take so much time and energy to help me with my fitness. As someone who knew nothing of the fitness world, Saraii has helped me every step of the way. Through every physical barrier and mental barrier, she has been there to support me and push me through.

I can never thank her enough for her hard work and dedication to her members. Truly a remarkable place. I would recommend to everyone.

I’ve been going to Gritt since November and it’s been an amazing experience! Coach Sarai is awesome and I always look forward to the sessions. Coach Sarai is very attentive and provides thorough workouts to help our needs. There are sessions for kickboxing and sessions for strength training and coach Sarai makes sure to provide accommodations to any member who needs it. She also makes each session fun with her comments and she makes sure to help us improve our form as well, encouraging us along the way. She has also helped me with my nutrition plan and I’ve been seeing progress these last few months :)

GRITT is such an amazing place. Coach Sarai is so down to earth, she cares for each and every one of her members. My experience at GRITT has been a one of a kind and i wouldn't trade it for anything else. Coach Sarai has an extensive knowledge between fitness and nutrition. I'm an active person and tried my best to see results on my own and it wasn't possible, but with Coach Sarai i've seen results in a short amount of time. As long as you listen to her instructions, anyone will be able to reach their goal. I look and feel different, it is all thanks to OUR AMAZING COACH, who takes the time to speak to us one on one and motivates us. I am so thankful for meeting Coach Sarai.

Boxing and aerobics are the most fun I have ever had exercising and I enjoy the positive attitude from the staff. The routines were tough to keep up with at the beginning but as you build endurance they become more enjoyable. Sarai is very supportive and encouraging and as a result I probably work harder than I would ever push myself at the gym.
If you are trying to lose body fat, the body composition analysis they do it's a great toll to keep track of weekly progress, it has helped me to remain engaged and motivated. Over all great quality service for the price.
