Fitness & Gyms near South Hackensack, NJ

“Amazing gym! There are so many different kinds of equipment and it’s always so clean! I feel like I am slung other athletes which I love! People are nice and kind. The offer so many different things! I love this gym. It gives me the motivation I need and comfortability I was looking for!”

“Wonderful front desk staff , Emma makes me feel so comfortable and welcome , there’s a sales person named dez who is one of the coolest down to earth people I have ever met”

“Completely changed the shape of my body. I did personal training at equinox for years and I wasn't seeing results. They told me it was the natural shape of my body, I knew it wasn't because of how my body looked for the 27 years before that. Form50 got me back to feeling like myself again. The program is always challenging and there are plenty of ways to modify. I can't believe how knowledgeable each instructor is, you're in great hands with anyone. The energy, music and program have never let me down - even after 2 years. Thank you form50!”

“I can hardly believe it, I've finally found the perfect workout class studio that also happens to be a woman-owned small business (bonus!). The instructors are fantastic. The classes themselves are low impact so I never feel like I am going to injure myself even though I am working hard. Each workout move in class is given many options to fit all abilities. I've come to trust the workout system they have and know that if I keep sticking with it I'll continue to gain strength and flexibility.

The studio space is gorgeous and so thoughtfully put together. It feels lux and like home at the same time. The staff and the others (mostly women) working out are friendly and this is a place where one could meet friends, or at least create a support circle. It feels nice being recognized by others in class.

As a side note, a Trader Joe's is just steps away, which is a post class highlight for me, as I don't live near one.”

“We loved the class we took with Coach Chris. He was very kind with our kids. At the same time he pushed them and motivated them to try their best. I recommend the class without any doubts.”

“Gotta talk about the Trainer ANGEL.
He is kicking my ass. And it is changing my life and giving me structure. Coming back from a previous “fit” life, I salute how he is restoring my legs and shoulders with shape and size. How can he know so much while still being young?! A Natural Leader. GREAT sessions! Thanks ANGEL & TMPL. —Jono M. West Village”

“I have been wanting to get to the gym for a while now and finally decided to join Rock Fitness since it is so close to where I live. I’ve only had a tour and orientation, but I’m already looking forward to going back. The place is very nice. The staff is friendly and helpful. It’s been a great experience so far.”

“Im a college athlete who needed a gym during winter break and I came here on a 3-day trial and ended up signing up and I would do it again. Im not a talker when I workout but you can feel the good culture they have set up I recommend it to anyone. The exact opposite of a toxic gym environment.”

“Strength Center has truly been a game-changer for me. I joined early last year, looking to get stronger and healthier and I got so much more than that.
The coach-led classes are thoughtfully designed, tailored to challenge you at your level, and focused on real strength building (not just going through the motions). The programming is smart updated periodically, the pace is just right, and there is always a coach nearby to guide your form, push you when you need it, and celebrate your progress.
What really sets this place apart is the team - they are genuinely invested in your success. From thoughtful feedback to nutrition tips and lifestyle advice, they care about the whole journey, not just what happens inside the gym. I have learned how to build healthy habits that stick, and I feel stronger, more confident, and more energized than ever before.
If you are looking for a gym where the coaching is high-quality, the environment is welcoming, and your progress truly matters, Strength Center is it. Can’t recommend it enough!”

“I've been going to MFF since starting Snatched in 2014. The irreverent approach to making fitness fun plus the training on good form and technique kept me coming back for more. In fact, I feel like at this point I am confident every time I workout with instruction I received over the years. The part I didn't expect was the community and friendships I've built going to MFF. I love MFF and would recommend anyone to give it a try!”

“I really love Orangetheory! The coaches are incredibly friendly, motivating, and make every class enjoyable. The front desk staff is always welcoming, and the studio is spotless. There’s also a great sense of teamwork that keeps you accountable—if you skip a class, you definitely feel it!

The only reason I’m taking off one star has nothing to do with this studio—it’s about the corporate-designed workout structure and layout.

The classes are about 50–75% cardio, and the strength sections can feel cramped and a bit disorganized (like doing jump squats right next to someone doing push-ups). The limited space feels tight and sometimes unsafe, and the weights don’t go very heavy. This is especially noticeable with legs were often people are looking to grab 50-60 pounds.

Also, the app asks you to rate the class but doesn’t let you explain what specifically you liked or didn’t like—so it’s hard to give accurate feedback when you might love the treadmill but not the particular weights or rower.

Overall, this studio is amazing with top-notch staff and energy. The lost star is solely due to corporate programming and design, not the incredible local team!”

“I have plans to move to NY and I tried Spot crossfit. I met coach Rashad, Raul and Jessie they were all great made me feel at home and very professional teaching every detail of the movements, they’re very passionate of what they do. I’ve been doing CrossFit for almost 10 years and the most important thing in a crossfit gym, which is a community based gym, you find here. It’s like a big family. Thank you all, be back soon.”

“One of the best gyms I’ve been a member of. It’s clean, well-maintained, and never feels overcrowded. The equipment is modern and the staff is friendly. Also love the 24/7 access. Highly recommend.”

“Incredible concept, coaches are great and very attentive to the form of movements.
They always have the good words to keep your energy up and get the job done !!!
Everything is clean and neat, biggg +++”

“10/10 recommend Synergy! A smaller gym that really is more of a community. Tons of equipment and very clean. The staff is amazing - Ray (the manager) is always so attentive and kind. I am going to miss this place so much! Always the highlight of my day!”

“This year i decided to start my fitness journey, and i was nervous on where to go i was afraid i would feel intimidated, but i made the right choice by coming here. Everyone is welcoming specially one of the staff members i think her name is afnan, she was very sweet.”

“I dropped in at this box a week ago while visiting NJ and I couldn't have a better experience. The coach Angelica had great energy, empowering everyone, the attitude you expect when you train CrossFit.
I have absolutely no regrets, a fun workout, great facility and nice people.”

“I’ve been going to this location for a year and a half and could not recommend it more! The trainers are great (particularly Meredith and Ben), the facility is always looking good and the classes are challenging without being overwhelming.”

“Fast Twitch is the perfect facility.. It has great trainers and programs to get your body right and the gym has a great vibe for student athletes. I have 3 boys who play baseball and they enjoy it. Fast Twitch's pricing is also very reasonable.”

“Are you serious about powerlifting? Look no further than this hidden gem—the ultimate haven for strength enthusiasts. The equipment here transcends what you’d find in a typical commercial gym. It’s like comparing night and day. Everything is meticulously designed and, dare I say, tight. Forget the notion that a barbell is just a barbell or that a 45-pound plate is merely a 45-pound plate. This place defies those assumptions.As we age, injury prevention becomes paramount. To ensure I wasn’t compromising my squats, bench presses, and deadlifts, I booked a 2-hour technique session with Jason. Worth every penny! My high bar squat was decent, but I craved better posterior chain development through low bar squats. Jason’s personalized tweaks transformed my form from “okay” to rock-solid.Now, let’s talk bench press. It’s always been my Achilles’ heel, but Jason—a bench press monster—guided me through drills that revolutionized my approach. After just 30 minutes, I was lifting more efficiently, engaging additional stabilizing muscles, and driving the bar with newfound confidence.Surprisingly, my deadlift form needed the most work. Despite countless YouTube tutorials, nothing compared to hands-on coaching. Jason helped me recruit the right muscles, optimize leverages, and—most importantly—lift heavier weights safely.My only regret? Not seeking this guidance sooner. I eagerly await the day when I can join this gym and take my training to the next level.”

“As 2025 comes to an end, I want to give a huge shout out to all the coaches at Orange Theory. (Don’t make me pick my favorite child!). Nick, Connor, Zach, Cat and Jenna are all awesome, each bringing great energy and creating such a fun and supportive atmosphere in the classes. They also have found ways to improve my form, or give me other personal tips which is particularly impressive given the size of the class. I am 56 years old and I have never felt stronger in my life. Thank you guys!!”

“I highly recommend Ms. Allison enough as a swim instructor. My 4-year-old son started lessons with her a few months ago, and the progress he’s made is incredible. She’s warm, patient, and has such a gentle way with young kids, making them feel comfortable right from the start.
During each 30-minute lesson, she’s fully focused on the kids, and it’s clear how much she cares about helping them succeed. Thanks to her guidance, my son now floats on his own and has totally overcome his fear of water. He actually loves swimming now and can’t wait for his lesson every week. Ms. Allison has been a true gift for us!”

“My home CrossFit gym <3 haven’t been in awhile. My partner and I both go here. Friendly for everybody. A priest, monk, and a rabbi could walk in for a CrossFit class and walk out without any problems- and that’s coming from a catholic and her gay sister {and her partner Shannon who said this place is her family who’s a nurse.} My point is this place is very inclusive for everyone, and is really about including everyone, and I mean everyone everyone. And I’d feel safe bringing family members or even my own kids here. Loved my experience here and it’s very secure. Getting in touch with them can be difficult via phone call but they reach out via text message immediately so it’s well worth the wait. The memberships are up there, but if you’re a full fledged crossfitter, you’d rather by a membership here than anywhere else. I play soccer in New York City, and on Long Island and My partner is a Police officer for the city, as well as family- and a lot of members in this gym are former military or Law enforcement or fire department members who are non-discriminatory and extremely friendly. One of the best experiences I’ve had in awhile. Worth every single dime, and worth the wait. We travel from Long Island to come here, and it’s worth it. Great job guys :) looking forward to come in soon.”

“I took my first class with friends at the Chelsea location yesterday, and it was intense in the best way possible!!! The staff were very professional and incredibly friendly. The space itself is clean and cozy, with everything perfectly prepared for our workout.

By the next morning, I could already feel positive changes in my body with that good soreness, and my friend felt the same way. I love feeling results so quickly. I can’t wait to go back for the next class. I’m so glad I discovered Iron Bodyfit :)”

“I joined Revive 3 months ago and it was the best investment I’ve made for myself in a long time. I really love the variety of intimate classes offered & convenience of having the workouts laid out for you. The coaches are super passionate about helping you reach your goals and I immediately felt welcomed by all the members. ? recommend this gym!

UPDATE!!!! I have now been part of the Revive HIIT community for 15 MONTHS and still absolutely LOVE IT. It has become part of my weekly routine 3-5x per week without hesitation. The coaches are incredible and know exactly how to push me to my maximum effort and keep me accountable, which is something I always struggled with on my own. The strategically designed workout plans have helped me lose 50+lbs, gain new muscle and significantly reduce my stress. I am SO excited as they are ready to move next door this week into a larger facility with brand new equipment and perks for all the members!

The energy here is unmatchable.”

“I love this gym. This gym felt like my second home! TMPL Astor Place was a place I knew I could keep my stresses at the door, and just focus on my self and my fitness (physically and mentally). I recommend this gym to anyone who wants a warm welcome by the amazing staff and consistently clean equipment and floors. Unfortunately, I had to cancel my pass because I moved to Los Angeles for a new job (bittersweet) - I hope TMPL opens in LA !!!! LA needs better gyms !!! Special shoutout to Natalie Ramirez for making my time at TMPL so great - She’s such a professional and her hospitality is top notch!”

“Great place, great customer service. Friendly Team and it's not just a gym but it's like a family place and they care about their members.There are group exercises classes also like Zumba, Yoga, Bootcamp, Spinning...etc.There are many machines disponibles to all members and you don't have to wait or to be in queue. There is a free parking also and the location is easy to reach it.Thank you Matrix Fitness Club's Team.”

“The gym is filled with incredibly supportive and helpful people that are invested in making sure you succeed in your fitness journey. Its a great environment all around.”

“Great Gym, got myself a weeks pass had quality workouts on good equipmentVery clean. Liz was great she was helpful and informative, would definitely recommend this gym”

“F45 Flatiron is great! My experience here has been wonderful. Coaches are extremely supportive and knowledgeable. I would recommend anybody to come here looking for a good group workout class.”
