Jay's a great trainer! He really pays attention while you're exercising and is quick to point out issues with your form of if it looks like you're compensating. I found the workouts he gave me challenging but achievable, and overall he really helped me learn how to work out.

His gym is also clean, pleasant, and private which is a huge plus. Would highly recommend.

I joined the group training sessions to strengthen my core before planning for pregnancy, and I absolutely loved the experience! The workouts were fun, motivating, and really effective. I felt stronger and more confident each week. And guess what? I even got pregnant afterwards! I highly recommend group or personal training, whether you’re getting ready for summer or preparing your body for pregnancy. It’s 100% worth it!

Working with Mr. Park has been an incredibly rewarding experience.
His personalized and systematical approach provides not just clear guidance but allows his students to understand how and why certain forms, steps, and related actions are needed.

He always makes an effort and time to listen and to understand the needs and responses of students. He always takes an extra distance to help understand student's needs.
(Mr. Park even attended my child's sports event on his off day to observe and monitor his progress. What a dedication and support!)

His process is not only incredibly motivating, patient, and supportive, always directing just the right amount of support and encouragement to be the best and ensuring proper forms are maintained to avoid injury.

I highly recommend Mr. Park to anyone seeking a dedicated, effective, and passionate personal trainer.

I had an amazing experience at Main Fitness in Fort Lee, working with Jay! I followed a 3-month program for two rounds, and the results were incredible—I lost 9 pounds and feel so much healthier now. Jay was extremely knowledgeable, motivating, and tailored the workouts to my needs, he KNOWS what he is doing! The facility is clean, well-equipped, and has a positive atmosphere. I highly recommend Main Fitness and Jay Park to anyone looking to improve their fitness journey. I’ll definitely be recommending this place to my friends and plan to come back next year. Thank you Jay!

Jay took the time to listen to my goals, assess my current fitness level, and design a program that was perfectly tailored to my needs. Each workout is thoughtfully planned, challenging, and engaging, focusing on proper form and technique to maximize results safely. He creates an encouraging environment where you feel empowered to push past your limits while making the sessions enjoyable.

I started training with Jay back in February to lose weight and reduce body fat for my wedding photoshoot. I’d worked with other trainers before but never saw real results—Jay was different. His workouts were tailored, effective, and always exciting.

Jay incorporates a mix of strength training, cardio, conditioning, functional fitness, and even Olympic weightlifting movements that made training both fun and empowering. Each session was unique, keeping me motivated and ensuring consistent progress.

In three months, I lost 17 lbs, reduced my body fat percentage from 31% to 19%, and gained lean muscle. But more importantly, I developed a genuine love for working out, particularly strength training. Jay’s scientific approach not only got me in shape for my wedding but also set me up for long-term success.

What truly sets Jay apart is his care for his clients’ overall well-being. When I experienced lower back pain, he taught me recovery exercises that built a solid foundation for improvement. His knowledge and adaptability ensured every session aligned with my goals, whether it was mastering functional movements or improving sport performance.

Even after my wedding, I kept training with Jay because the workouts were enjoyable and effective. Now that I’ve moved away, I still book sessions with him whenever I’m back in town. The skills and habits I gained from his training have transformed my approach to fitness.

If you’re looking for a trainer who’s knowledgeable, innovative, and deeply invested in your success, Jay is the one. He’s not just an amazing trainer—he’s also a great friend. Highly recommend!

This approach has not only boosted my physical fitness but has also had a positive impact on my mental well-being.

Jay 선생님이랑 7년전에도 운동을 배웠었는데… 정말 그때 몸도 좋고 코어도 단단해지고 플랫했던 엉덩이도 친구들한테 엉짱이란 별명이 생길정도로 빵빵해 졌었어요!
그때 운동 중독증이 생겨서 선생님 덕분에 꾸준히 운동을 계속 했었어요.
아이 출산하고 키우고 정신없이 지내다가 역시 혼자 운동하는건 한계가 있더라구요.
다시 선생님들 찾아가서 배우는데..
제가 고관절이 많이 않좋아서 계속 고생했는데
선생님이랑 교정에 촛점을 맞추면서 운동을 시작했는데 점점 좋아지는게 느껴지는거예요! 한국 미국 병원에 가도 운동만 하지말라고 하지 특별하게 좋아진다 느낀적이 없었는데…
운동뿐 아니라 전문적으로 공부를 하신분이라 그런지 다른 피티 선생님들이랑 확실히 다릅니다.
이론적으로 배울수 있는 부분이 정말 많습니다.
운동을 할수록 선생님 지식이 정말 많아서 감탄이 나와요.
무엇보다 선생님이 인간적이시고 마인드도 좋아서 그런점에서도 배울점이 많다는게 참 좋습니다. ^^

인생을 건강하게 바꾸고 싶으신 분들 Main fitness Jay 선생님을 추천합니다.

딱 눈감고 6개월만 꾸준히 가보세요.
인생이 달라지는걸 경험할꺼예요!

I'm glad I discovered this gym when I started my training journey this year. One of the standout features of this gym is its cleanliness; it is always spotless, which I appreciate a lot. Jay has been wonderful. He is very patient and helpful, even to newbies like me, and I have learned so much about the foundations of training, thanks to his expertise and guidance. His ability to break down complex exercises and techniques into manageable steps has greatly improved my confidence and understanding.

Jay is awesome and I'd recommend him to everyone I know! My mom (who is in her 80s) stayed home during COVID and developed a difficulty walking, which got worse with time. Then we came across some great reviews about Jay helping seniors with mobility issues. My mom has been seeing Jay for a couple of months now and she LOVES these one-on-one sessions with him because it is customized just for her and highly effective. I sat through a few sessions myself and I love how it’s interactive where Jay would try different things and my mom would ask questions as much as she likes. Jay is extremely caring, thoughtful, skilled, and most importantly FOCUSED on RESULTS. I strongly recommend personalized training with Jay to seniors and those who have mobility issues.

After taking a break from exercising for a few months, I noticed my muscles loosening and my back started hurting, which led me to this place. The space is well-organized, making it a great place for beginners to learn various exercises. I'm grateful to Jay for thoroughly checking my physical condition and gently guiding me. Despite my busy schedule, I'm receiving help, which I appreciate. It's also nice to be able to exercise quietly without disturbing others.

I've been training with Jay for almost two years, and it's been an incredible journey. Not only is his training facility always spotless, but Jay also brings a wealth of knowledge to each session. He tailors workouts to my personal needs, taking into account my age and experience level.

Started 2:1 class with my mom and it has been around 4-5 months since. I always struggled to gain weight overall whether that be fat or muscle. After starting here, I gained over 5 lb in muscle/fat!! This might not be a lot to some people but it is a HUGE deal for me as even gaining 2 lbs and having it stick was always impossibly hard. After workouts he would send videos of us to show the proper posture so we could also work out on our own. Even though it was a 2:1 class with my mom, he would tailor the workouts to our personal needs whether that be weight gain, bad posture, or hip/back pain. My mom recently hurt her hip/leg to the point where she could barely walk and/or lift her arm above her shoulder. After coming here, she has seen visible improvement and says Jay really knows what works for each person. If a certain workout didn't work for her or was too painful, he didn't just give up and move on, he would customize it accordingly. He is super nice/funny and makes the workouts enjoyable and not a dread. SUPER RECOMMEND!! :)

Main Fitness에서 남편이랑 저랑 같이 운동을 시작했어요. 남편이 장시간 앉아서 일하다보니 허리가 안좋다고 해서 제가 PT를 받아보자고 제의를 해서 시작하게 되었어요.
생긴지 일년정도 되어서 정말 깨끗하고 쾌적한 환경과 기구들도 좋고 저희부부는 수업을 받고나면 몸과 마음이 항상 좋았어요. 그리고 남편이랑 같이 2:1로 수업들으니깐 서로 의지도돼고 재미도 있었어요.😊
선생님도 너무 좋으세요. Jay선생님과 운동을 시작하면서 저희남편 허리도 좋아졌고 몸상태를 먼저 잘 체크하시고 부상이 생기지않게 그사람의 상황에 잘맞는 운동을 해주셔서 남편 몸상태가 좋아지고 근력도 좀 생기고 코어운동도 많은 발전을 했어요.😃
그리고 신기한거는 몸이 좀 결리고 뭉쳐서 아파서 간적도 있었는데 나올땐 몸이 희한하게 가벼워져서 나옵니다. 항상 몸에 잘 맞는 운동을 알려주시고 안되던 동작들도 되게 만들어 주시더라구요.
신체의 변화를 느낄 수 있을거에요.
강추 드립니다.!👍

I've been working with Jay for the last 12 weeks and this has been my first experience with a physical trainer. At first, I definitely was apprehensive - I mean who wouldn't be? 3 years of Covid definitely doesn't help keep people in shape. But Jay designed the workouts to suit my needs while pushing my limits. He's explained the science and the methodology he's taken in building the workout and there are tangible and measurable results to be had.

To anyone hesitant to take the plunge; I'd highly recommend it. It's been a great experience and one I am going to continue.

Jay the trainer took the time to understand my specific needs, goals, and limitations, ensuring that each exercise and routine was tailored to suit my abilities.

If you're looking for a personal trainer who will push you to your limits and help you achieve your fitness goals, look no further than the 1:1 personal trainer at this state of the art boutique gym.

From the moment I walked in, I knew I was in good hands. The gym is immaculately clean and modern, and the equipment is top of the line. The personal trainer, Jay, greeted me with a warm smile and took the time to get to know me and my fitness goals before we started our first session.

Throughout our sessions, the personal trainer pushed me to work harder than I ever have before, but always with an eye on my safety and well-being. He kept me motivated and accountable, and I could feel myself getting stronger and more confident with each passing week.

What really sets this personal trainer apart, however, is their attention to detail. He carefully customized each workout to my individual needs and preferences, and never hesitated to adjust the plan based on my progress or any injuries or limitations I was experiencing.

Overall, I can't recommend this personal trainer highly enough. He is truly a fitness expert and a pleasure to work with. If you're serious about reaching your fitness goals, this is the trainer for you!

I've been wanting to find a personal trainer who can help me get more toned and fix my bad posture. I've learned so much about my body the past 1.5 months here -- where my strong/weak parts are, what simple stretches I can do to help loosen my tensed muscles, and what targeted exercises I can do to strengthen my weak points -- meanwhile focusing on gaining strength in all parts of the body. Overall I am very happy with the sessions and I am already feeling improvement in my weaker areas. Also the gym is very clean which is a huge plus!
