Fitness & Gyms near Warren, NJ

“I began working out at this gym in October. I really appreciate the energy and encouragement. The coaches provide. They are extremely knowledgeable and supportive making changes to the workout plan to accommodate moves that require modification.

I highly recommend this gym to anyone looking for a helping hand to get back into working out as it’s done. Amazing work for me.”

“As someone who is not a gym gal, orangetheory has been the perfect place for me to become one. I joined because i was going on vacation and my coworker recommended orangetheory to me. I love the accountability aspect you are held to. I paid for a planet fitness membership for two years and never stepped foot inside, at orangetheory if you do not cancel your class within 8 hours you owe a cancellation fee. The amount of times i dread getting up and out of bed but only have 2 hours before class starts, you best believe im getting up and going and afterwards i never regret moving my body. Now i have a routine down, the coaches are so patient and take time explaining when i am lost, i never thought id actually enjoy the gym but i love orangetheory”

“I joined F45 South Edison Feb this year and absolutely love it. I needed a challenging, motivating, group-style workout regimen and a sense of accountability so i show up whether i feel like it or not, and f45 totally provides this. The coaches are super knowledgeable and supportive during the entire workout. Coach Gabe and rly all the coaches are amazing - they stay engaged and give you tips on improving form and technique. I love how it's a different combination of workouts each time. The group atmosphere of like-minded people, detailed coaching, and pump-up music always pushes you to go hard and get better. Really great place.”

“I’ve been coming here for almost 4 years - I love it! They always work with me to adapt the workouts as needed. They hold me accountable & make sure I’m using optimal form to hit PRs.”

“Staff is welcoming and cares about your success and building relationships. Helped transform me into a more explosive, fluid, and stronger athlete. Highly recommend for athletes looking to play in college.”

“My happy place, not just a gym a community & safe place!! No matter what your level of fitness or injury there is something for everyone. People come in looking for a gym, find their people & stay for yrs. Tim & Erin are not only business owners their all around incredible people!! And the coach’s are just fabulous!! They care & want to push you but safely. I can’t say enough about 908, try it and you’ll never want to leave.”

“On Friday I had my first PT session with Spencer. The experience went far beyond my expectations. He is an excellent instructor. Very professional yet personable. I look forward to working with him in the future to maintain my fitness goals.”

“Joining OTF has been one of the best decisions I’ve made in a long time. I’ve tried MAX, Crossfit, hot yoga, the gym, you name it, but OTF has been the best fit for me. It’s the perfect workout for weight loss and gains. I love going to Grace and Hayden classes. The staff are wonderful and I can’t wait to see where the rest of my journey here takes me :)”

“I have both of my kids enrolled at Swimming Splash Academy, and I want to give a big shout‑out to Miss Karen and Miss Kayla. I have seen significant improvement in my kids’ swimming skills, including their confidence with different strokes.
Miss Karen consistently goes the extra mile to ensure each child understands and follows instructions. If a child is having difficulty understanding, she patiently demonstrates the technique and makes sure the child is able to follow along correctly. Her dedication truly makes a difference.
The facility itself is excellent—the pool is always clean, there are multiple lifeguards on duty, and the shower rooms are well‑maintained and spotless.
I would definitely recommend Splash Academy to other parents who are looking for quality swimming instruction in a safe, clean, and supportive environment.”

“I cannot say enough amazing things about this gym. I have not only learned so much physically but I have gained a family. I scale pretty much everything so do not think crossfit is something you cant do. They have options for all levels. Great gym and great people.”

“Monarch is an amazing gym with an owner and coaching staff who genuinely care about their members. They take the time to get to know you, check in on your progress, and make sure you feel supported, safe, and confident in every workout. The workouts are challenging but well-scaled for all levels, and the community is welcoming and encouraging. Highly recommend.”

“best public gym in area! i am a strength coach myself and have tried all the public gyms in area and this one is the best… from the equipment, cleanliness, lighting, and sauna. PLUS, it’s next to a fresh fruit/veggie market.”

“A word to the wise- don't wear a thermal or long sleeves on your first workout back in a while... This was my FIRST ever classpass class, and it was a wonderful workout to get my head back in the game!! Coach Quentin is all smiles even at 9:30AM and such a welcoming presence. All of the regular gym members created such a safe, kind, friendly, and encouraging space- I truly couldn't have had a better experience! If you're feeling intimidated or uncertain about attending class workouts, this is a great way to get started. Coach Quentin was able to patiently guide me through the workouts and even supportive with any modifications that I needed. Highly recommend and will definitely be returning for additional classes :)”

“Trainers walk you thru exercises and verify you lift correctly to maximize the benefits and reduce injury. I lost weight, gained strength, balance and flexibility I never thought I could achieve! I can do v-ups and push ups now! My core strength is the biggest change I have noticed after being morbidly obese most of my life I actually have a waist now! At the beginning of my time I was out of breath and a hot sweaty mess trying to keep up with the routine, now I do the routines with minimal sweat and can do the more challenging version of the exercises since I have balance and strength now!”

“I am a 70 year old volunteer EMT. I was starting to feel like I wasn’t fit enough at this age to do the job I have been loving for 10+ years. Maria makes sure my form is perfect for lifting. She has improved my ability to walk and carry heavy and she is working on my balance. I feel 10 years younger and my ability to get up and down and work around obstacles gets better every day. We work one on one twice a week and she even has me exercising at home. I highly recommend!”

“The only gym/workout I've ever stuck with. I've been working out with Dave for over 12 years now. The workouts are constantly changing and always challenging. The nutrition plans keep me in check. I have never felt better! The best way to start my day!”

“Such a great gym! Would 100% go here if we lived in the area and will definitely be back for drop ins. Thank you Billy for building a CrossFit gym that is everything CrossFit is supposed to be.”

“I’ve been a client of Malik Wright at awesome body sculpting for many years. He is an expert at what he does. His ability to motivate and inspire makes him one of a kind!”

“This was my first time throwing an all kids birthday party, and thank goodness for my gum. They really took care of everything all I had to do was show up with the balloons! My daughter and her friends had an amazing time. Our two staff members who ran the party were AMAZING! I can see why people come back year after year. I will definitely be doing it again next year!”

“Love this place. Great atmosphere, great people, generally, they are focused and full of knowledge, have a wide range of equipment for people of all levels, look forward to continuing on there!”

“I normally don’t write reviews, but my experience at The Chatham Club has been exceptional. The facility is well-equipped, clean, and the staff is consistently polite and professional. Definitely a 5 out of 5!

What truly made the difference for me was working with my personal trainer, Mr. Brian Feretich. I started coming here after completing physical therapy for a serious herniated disc, and Brian’s expertise and personalized approach were exactly what I needed.
His deep knowledge, careful guidance, and motivating energy have made every session both enjoyable and effective. I highly recommend him—and the Club—to anyone looking for a supportive and high-quality fitness environment.”

“Stellar local gym. The owner, Gary, is very sweet and really cares about people & his facility. It has all the equipment you'd need and it's never crowded so I've never had to wait in a line for something I've wanted to use. The equipment and decor all share a unified retro aesthetic. Everything is kept extremely clean - I see the owner cleaning basically every night. This all leads to the atmosphere of this gym being very calming, perfect if you favor a quiet relaxing workout experience. Lots of mirrors and high windows letting in natural light. I just can't imagine using a crowded noisy commercial gym after frequenting this place.All the patrons are very friendly. Besides weights, there are cardio machines, a martial arts dojo with classes offered, personal trainers, spin bikes, and more. I've been coming here over a year now and it's become my new happy place.”

“I was driving by a year ago, headed home from grabbing a bunch of sod for my yard and I saw the gym. There were people running outside and other inside doing power cleans. Curious, I stopped and went in to inquire. I’m a former college athlete, and a veteran who’s tried to stay in shape. I was at the regular gym about 3x a week and running outside once per week. I’ve always been a traditional lifter, never into CrossFit even though a lot of folks I deployed with were. As soon as I walked in, you could feel the community and love. I could also immediately see fitness. It’s the gym so, yeah, naturally you’d see it, but this was different. CrossFit training is basically Olympic style, so their bodies look better than a lot of the most fit people who do traditional training. Even though I was a random inquiring about pricing, it was all love and they made me feel welcomed immediately. I did the free class to see how it was, and was blown away. The workouts were grueling, yet fun. It was addicting knowing I went so hard and was challenged. The coaches make sure everyone works within their limits and pace, while nudging and getting the most out of each person. It was balanced. Half strength, half conditioning, and always full body. A litany of stretches and warmup before, and again at the conclusion of the class. I signed up immediately for 12 classes per month, but was hooked and had to increase to unlimited. My wife and I both attend - and she’s always been a pilates gal. Her loving it as well was yet another sign of the quality and care. It’s a great feeling of having a community you’re part of pushing you to live a healthy lifestyle across the board. The coaches are knowledgeable, caring and fully invested in YOU. I feel an innate closeness with each as well as with my teammates I workout with. The balance of programming weekly is amazing too - Sundays & Wednesdays are “Engine” days which is a lot of conditioning and burned calories. Monday/Tuesday/Friday/Saturday are “Hybrid” days which are always balanced, half conditioning, half strength straining. Those are always tough but balanced. Thursdays are “Power” which is strength!!! And you can count on every workout including core and abs somewhere somehow. It’s so comprehensive you’ll see results pretty quickly. The gym also partners with an outstanding meal prep service if you need help building a healthy diet and are too busy to cook or count the calories and macro/micro. And if the classes aren’t enough - you can request and pay for personal training with any of the coaches which’ll elevate you even more. It’s truly a world-class staff and experience. You start stacking the days and making friends while watching the results….truly a wonderful feeling. The gym has so many collaborations with other fitness communities, charities to give back, and other organizations that share the wonderful values and passions of Fortitude. Whatever niche of fitness you’re into - Fortitude has people there into it; from CrossFit like Hyrox, to the marathon and half marathon runners, to the power lifters, and competition people. I’m constantly pushed to become better, stronger, and healthier by classmates and coaches alike. I’m nearly back at my size from undergrad playing days. I’m glad my wife encouraged me that day we were driving by to go in. I cannot recommend Fortitude enough.”

“After a spinal injury and sleeping in a chair for almost a year, I was ready to get back to living. I found Soo and have literally experienced a miraculous recovery with greatly reduced pain and increased mobility in a very short time. My wife and I are blessed to work with Soo and words alone cannot express the gratitude we feel. She is one of a kind!”

“CrossFit is for everyone! Stealth is such a welcoming place and I love the attitude that you’re competing against yourself to get better. You can see your strength improve. It’s a wonderful community if you want that too but not required. All workouts can be scaled back to be accessible to people of all ages and fitness levels. The workout is different every day which keeps it fun and exciting.”

“Best for power lifting, fitted with all the machines for your lifts and supplemental machines to help build strength. Hiroshi is a knowledgeable and methodical trainer who will work on maintaining your form, which reduces or eliminates injury while getting you stronger. There are also cardio machines so you get a nice blend of options for your needs. I trained here before, during and after pregnancy and it was a gamechanger for building and increasing strength, maintaining and rebuilding after I gave birth. Definitely recommend.”

“I’ve tried many massage therapists and physical therapists over the years to heal my pains from running, pickleball, hiking and skiing. I’ve had the most success, out of anyone I have tried, with Michelle Frost. She has a skilled, intuitive almost magical sense and quickly knows how to prod and cajole my muscles, resolving an issue that has persisted for months. She just fixed my pickleball shoulder and very sore hip. I now live out of state but find opportunities to come to NJ to visit Michele at Providence Health. A unique massage that yields great results.”

“After two years of treating a back injury, with little exercise possible, my doctor sent me to Mark to get my body and especially core stronger. 15 months later, I hardly recognize myself- stronger, more confident, less fearful of re-injury, about to return to golf, and, an unplanned bonus- my bone density has progressed significantly, and from osteoporosis to osteopenia! We’re now working towards normal bone density. Mark is kind and reassuring, but doesn’t accept my own ideas of my limitations, and firmly encourages me to what he knows is possible, but never over steps. Mark and Kristi personalize sessions to meet individual needs. Everyone is welcome. I can’t recommend them and Excel Fitness enough. Mark and Kristi are the best!”

“Great gym with excellent equipment and a very clean facility. CJ, the director, was extremely helpful and knowledgeable. He really knows what he’s talking about and does a great job breaking things down in a way that’s easy to understand. Overall, an excellent gym and a great director. Highly recommend.”
