Fantastic experience: Hands down the best gym in the area! They have all the equipment you need for all different ranges of exercises. Whether you’re training for powerlifting or bodybuilding or simply just want to take a fitness class (MIT)! Come check it out. All the employees engage with all clients that come into the which makes your experience very personal.

Fantastic experience: Tenacity fitness is a great gym with exceptional trainers, clean equipment and workout areas, and a friendly staff. I first came to Tenacity to train in preparation for a fitness test that I had failed a couple weeks before. I ended up working with a trainer named AJ for 5 weeks who crafted a specific workout plan to help me reach my fitness goals. He tracked my progress and routinely checked in with me outside of training sessions. He even encouraged me to workout outside of training sessions and helped me stay motivated in my training. After the first 5 week session I passed my fitness test and requested an additional 5 weeks of training. The experience at Tenacity was great. Every interaction was positive whether it was with AJ, other trainers, staff, or other folks at the gym. I cannot recommend the gym enough for anyone looking to improve their overall health and fitness. It’s a great place to workout and train.

Fantastic experience: I’ve been an inconsistent member for years. Started working with AJ again in March, got derailed for two months by a major abdominal surgery, and started right back with AJ as soon as I was allowed. He tailored my workout to what I could do while still healing, and now I’m in better shape than before! Best members, best coaches, best owners. It’s a place where an overweight 40something year old woman can feel comfortable working out beside super fit men and women. Love my gym!

Fantastic experience: Tenacity Fitness is pushing me to excellence. The family oriented vibe when I first walked in was very welcoming. I’m learning a lot. Shannon, my personal trainer, has a wealth of knowledge and with her guidance, I know I will smash my goals. My twin sister and I absolutely love her and highly recommend her to anyone who wants to see what their body is capable of. I’m so grateful for the opportunity. Highly recommend this gym to all of my friends and family.

Fantastic experience: Tenacity is hands down the best gym I’ve ever joined. Amazing facility, staff, and ownership. Highly recommend to anyone looking to join a new gym.

Fantastic experience: This is an excellent gym that my sister and I absolutely love coming to! We are extremely comfortable here. The staff are so caring and attentive. Shannan is an absolute joy to have as a personal trainer and we've learned so much! Thank you everyone at Tenacity!!

Fantastic experience: Absolutely fantastic facility!! I joined this gym years ago and couldn’t have been happier with my decision! The staff is supportive, motivating and create a welcoming environment for everybody trying to better themselves. I have since moved away and had to transfer to a different gym, but I can’t thank Steve, Bill and the rest of the tenacity staff and family for building my inspiration for physical fitness!

Fantastic experience: Joined Tenacity a couple months ago and had nothing but great experiences! Clean facility with friendly and helpful staff. After coming off of an injury Steve and Carol have been so helpful with teaching my how to use the equipment properly and showing me technics to help with my rehab. Highly recommend this Gym!

Fantastic experience: great gym with amazing trainers! not only do they offer classes, but they have a full equipped gym inside so you are able to get a variety of workouts. if you’re thinking about joining, just do it :)

Fantastic experience: Tenacity has been awesome to me in every way, it has all the equipment I need for a workout and it even has a bathroom were I can take a dump. Tenacity isn’t like planet fitness either, people hit new prs everyday at tenacity unlike planet were people cheat and say they hit a new pr on a smith machine!

Fantastic experience: The gym is an overall amazing environment and the punisher is a very beautiful man and will help you reach your goals.

Fantastic experience: Tenacity is like my second family! My parents have been going for a very long time, and all the coaches treat me like family. I always feel welcomed in the gym (even as a beginner), and they always answer any questions I might have. The gym is always clean as well.

Fantastic experience: At school and the gym, I usually struggle to work out and find things that work for me due to health issues and limitations. At tenacity, I do personal training sessions with Carol and I love how accommodating and amazing it has been. I have been going for almost two years now and I am so happy with my progress and how much my strength has developed.

Fantastic experience: I have been going to the gym for a while now and this place is great. Everyone is very helpful there if you need help. I have Steven as my personal trainer and he is the best. The personal training is the best way to get great workout. Thanks guys

Fantastic experience: Signing up for Tenacity Fitness was the best choice I made this year so far! It’s so awesome to finally have a gym that makes me feel 100% comfortable while doing my workouts. An added benefit is that the coaches, staff and owners are beyond helpful and treat you like family!

Fantastic experience: Absolutely the best gym I can think of. In august it'll be my 2nd year going and it keeps getting better. My trainer AJ helped me during quarantine gain nearly 60 lbs with amazing workout plans and helpful tips on dieting and even him watching videos of my sport to understand it better (Javelin) and to tailor my workouts to the movements I needed to do. I 100% recommend this gym to anyone looking for a super supportive group of like minded individuals who are all trying to get fit.

Fantastic experience: Our home away from home! So happy our family found this excellent gym 8 years ago! Great owners, supportive trainers and awesome welcoming members! From challenging MIT classes to up-to-date equipment, to trainers with all kinds of expertise, there’s something for everyone at every level. Highly recommend joining our Tenacity Family!

Fantastic experience: My son and I have been coming here and couldn’t be happier. The trainers are wonderful here and are always available for whatever you may need. This gym has everything you need. The MIT classes are the best . Highly recommend! Thanks Tenacity !

Fantastic experience: Love everyone at the gym! Specially Steve. Even though I pay for 30 minutes sessions, Steve always give me more than 45 minutes of his time! This is the gym that you want to go to where the staff really cares for you! Many thanks Tenacity fitness and Steve (the owner and a personal trainer).

Fantastic experience: Just joined this gym in October. Heard great things about it and never signed up. I totally regret not signing up sooner. This gym is like family. They knew my name after 1 visit. They helped me figure out a workout plan to go along with my running. The MIT classes so so great. It's like a personal trainer every time. On Fridays I do my own thing and can approach any trainer with a question to make sure my form is correct. They care about you 100 percent. The equipment they have is everything I need and more. Clean bathrooms and gym equipment. Now my son joined and feels the same way. So it has something for everyone of all ages and levels.

Fantastic experience: Absolutely LOVE Tenacity Fitness! My family and I have been working out there for nearly 8 years and can’t imagine going anywhere else. The owners, Steve and Bill, make us feel like part of the family. The trainers are excellent, the equipment is top-notch, and the MIT classes will challenge you. Join the Tenacity family, you won’t regret it!

Fantastic experience: Positive: Communication , Professionalism , Quality Tenacity Fitness is the BEST gym in Burlington Co! I tried multiple gyms before I found my "home" at Tenacity. They have the most amazing staff and trainers. It is such a welcoming environment with the most up to date equipment!

Fantastic experience: Most versatile gym around. No matter your age, lifting experience, or lifting style Tenacity has something for everyone. Clean facility and the staff is friendly and helpful. Great atmosphere all around.

Fantastic experience: This is without a doubt the best gym I have been to, and just one of my favorite places to be. There is all the equipment you could possibly need to get and stay healthy, the staff is amazing, and will always do anything they can to help you out. I’ve been coming here since it opened and I can’t say a single negative thing about it. If you’re looking for a new gym or a comfortable place to get in shape, this is it.

Fantastic experience: Tenacity Fitness is a top gym with great trainers that will help you hit your goals and answer any questions you have about fitness. They want to see you succeed here. I have made many friends and met a lot of cool people throughout my years being a member. They are always finding ways to improve and make the gym better for the tenacity family. This gym is a great gym for beginners or for experienced lifters and has an atmosphere like no other. Not only is the support system good here but this gym keeps you motivated to work harder and get better every time you walk in.

Fantastic experience: This place is the best! I found Tenacity when I moved into the area a couple years ago and am so glad I did. MIT classes are a great efficient mix of cardio and strength training. Coaches know you by name and care about both your progress and safety. Personal training is affordable and super effective. All of the personal trainers prioritize proper form and tailor exercises to your level and goals. Even my mom (a long time gym avoider) enjoys going to PT sessions with Shannan and has seen immense progress! Friendly, local atmosphere run by people that really care!

Fantastic experience: I have been apart of the tenacity community throughout the past 5+ years. After having a tough college schedule I had to take a break and couldn’t wait to get back this year. The owner, Steve, truly is not like any gym owner! Steve takes the time to create detailed workouts that fit your needs. The MIT classes are such a great environment where no matter your athletic ability, you are met with support and motivation! I couldn’t imagine going to any other gym! Amazing atmosphere and amazing owners!

Fantastic experience: This gym is AMAZING! I have been coming here for the past 4 months and it has been so great. As a former D1 track and field thrower, regular gyms usually don’t meet my workout needs. From preventative rehab, to flexibly-timed 30 minute HITT workouts throughout the week, to a top-notch certified staff of trainers, Tenacity is honestly the best gym I’ve ever been a member of. No matter your needs- whether you are undoing the damage of the pandemic (me!) or looking to recover from injury or simply incorporate functional strength into your workouts, you can definitely find what you are looking for here. Plus, it’s been tough to find a gym that takes health and wellness seriously in South Jersey during the pandemic, and Tenacity is second to none. None of the other gyms I’ve been to since they were allowed to reopen mandate masks and take sanitation and temperature checks with as much diligence as they do in this gym. Highly recommend working out here! Especially training with Coach Carol! She is the best!

Fantastic experience: Tenacity is my second home. Their sole concern is helping you achieve your goals, whatever they may be. I’ve been to many gyms in my lifetime, but none quite as special as tenacity. The facilities are on point and the staff is second to none. They’ve helped me to be in the best shape of my life. To have a facility that you actually want to go to is very important. No matter what your goals are, tenacity will help make them happen. It’s a great place loaded with fantastic people .

Fantastic experience: The best local gym in the area, always a motivating atmosphere. Trainers/owners are amazing people & are always willing to help you out in any way they can! I workout on my own but they offer MIT classes & PT sessions!

Fantastic experience: Hands down, best choice I’ve made training at Tenacity Fitness. VERY friendly team who make me actually want to go train. I look forward to walking through the doors and always feel amazing when I leave. Special shout out to Carol, she’s always welcoming, knowledgeable, very patient and a “drill sergeant” she provides me with the push and motivation I need.

Fantastic experience: Tenacity fitness is hands down the best gym around. The facility has top of the line equipment, and the owner Steve, is constantly bringing in new “toys” to keep everyone’s workouts fresh and exciting. The entire Tenacity staff is phenomenal, especially my personal trainer Donna. She always finds a way to make you push yourself harder than you thought you could and truly makes your workouts fun. All of the other staff is friendly and open to help and give pointers when you need it. Lastly the atmosphere is unmatched. All of the members have a camaraderie and push each other to work their hardest. Whether you’re looking for individual training, one on one or group classes, this place has it all!!!

Fantastic experience: Tenacity is the best gym in the area. Between the family type environment and the many different things they offer such as MIT classes and personal training I’m proud to call this my gym. When I came to Tenacity 5 years ago I had no previous gym experience and was barely able to lift 135 lbs. Over the past 5 years I’ve not only gotten stronger but I’ve also met friends that I’ll have for a life time. If you are looking for a gym that accepts anyone and everyone and can get you motivated Tenacity is definitely the place to come to

Fantastic experience: I can't say enough good things about my gym! Tenacity is top notch with incredibly knowledgeable coaches. The MIT classes consistently offer challenging workouts that will have you pushing your limits and realizing you are capable of more than you thought when you stepped in the door. I have been receiving personal training here at Tenacity for years and only occasionally took MIT classes. I recently discovered the benefit of mixing it up with the MIT classes on a regular basis. Not only is it always a great workout but it's also fun! The sense of camaraderie between the members is palpable. You are building strength and endurance while also building relationships. I LOVE TENACITY! Come check us out!

Fantastic experience: I'm so happy I found this place. Huge gym, excellent facility with great trainers and very modern equipment. When you check in, pleasant greetings by very nice people. They were instrumental with helping me with my diet and exercise routines resulting in healthy loss of significant weight. The gym has everything that the person needs to live a healthy lifestyle. Don't miss out, join!

Fantastic experience: LOVE Tenacity! I moved here about a year ago and was looking for everything Tenacity has to offer. Prior to moving to the area, I belonged to a very tight knit family style gym that offered HIIT classes - Tenacity welcomed me with open arms, the staff is phenomenal and the members are even more accepting of new members than I could’ve hoped for! It’s truly so inviting and in addition to their MIT section, they have a full open floor for weight and strength training. I’ve even worked closely with some of their coaches and they’re all so knowledgeable. As a personal trainer myself, I couldn’t say enough good things about this gym!!! Love them all and proud to say I’m part of the Tenacity Family! If you haven’t checked it out already, you’re missing out on a real gem!

Fantastic experience: In my struggle to find the right gym for me, failing my way through a system of big box gyms that focus on very predatory, negative aspects of fitness, I thankfully found Tenacity. I did so during a time where I felt completely disconnected from my physical body and was experiencing a major dip in my overall mental health. I started personal training with Carol doing corrective programming and I made huge progress even with just two days a week (as I know my threshold for burnout, I wanted to be patient with my body & mind). I've steadily increased to 3 MIT classes a week, 2 days personal training and I'm working on adding more time in currently. All this to say, I have more energy, I don't experience aches/pains from my office job anymore, I've never slept better, and I look forward to heading over to my gym, a place where I've been able to experience exponential personal growth. For the utilitarian folks— the scheduling system is very streamlined, the staff is knowledgeable and helpful, there are plenty of MIT class offerings throughout the week, the prices are incredibly reasonable & billing is very straight-forward. If you're looking for a smaller gym with a massive heart, I encourage you to check out Tenacity.

Fantastic experience: Tenacity is the best gym that I have ever been a member at. All of the trainers and the owners, Bill and Steve, treat you like family (I know it's cliche, but it's true) and are always there to help you with a spot or anything you need. The facilities are always clean and there's a variety of equipment for all of your needs, both cardio and strength. The MIT classes are great if you like instructor led high-intensity classes. Overall 10 out of 10 recommend!

Fantastic experience: Tenacity is a one-of-a-kind local gym that offers a better overall experience than other fitness centers. From free weights to machines, personal training to MIT classes, Tenacity has everything you need to reach your fitness goals. Above all, the staff will welcome you with open (socially distanced) arms to the Tenacity Family! I’ve been training there for over 7 years and highly recommend them to anyone looking for a quality gym experience in a professional environment and facility!

Fantastic experience: I’ve been to many gyms in my time from LA fitness to Lifetime. Each time I go to these type of establishments I felt like a number and their main goal was all about the “contract” and not my health and fitness goals. Not at Tenacity! Steve, Bill, and their staff are all super friendly and will know your name when you walk in the door. They will speak to you on a personal level and will address any of your fitness goals personally. The gym is clean and has all the equipment you will ever need. Whether your into the classes, powerlifting, Or you are just an average gym goer this is the place to be. I’ve made so many fun friends and I’m so happy to be a part of the tenacity family!

Fantastic experience: I am a proud member of the Tenacity Fitness gym. While the diverse equipment is Cutting edge, MIT classes are appropriately challenging and offered through the morning and night, personal trainers are extremely knowledgeable, it is the amazing culture that makes Tenacity Fitness special and the best gym I have been a member of in 30 years. The owners personal approach and sincere investment in their members ever changing goals is infectious and refreshing in a gym. You can feel this when you walk in for the first time. I drive from Medford and pass 5 other gyms to go to the Best Gym in the area, Tenacity Fitness.

Fantastic experience: This is hands down the best gym I’ve ever been to. The owners and staff are always around to help you out and are constantly willing to go out of their way to make sure you have the best experience possible! The staff is extremely knowledgeable and well rounded, so they have something for everyone. From experienced lifters and competitors to beginners to young athletes, they have everything! If you want to be surrounded by a great community that is focused around living a healthy lifestyle, this is your place! I’m so grateful I joined the tenacity family.

Fantastic experience: Tenacity has been the perfect community for my fiancée and I. We’re huge gym goers and we’ve been to a number of niche gyms around the country. Tenacity has that rare “gym atmosphere” that you can only get in an old school gym yet it’s still a place that’s incredibly welcoming for anybody at any fitness level. I walk in and see bodybuilders, power lifters, beginners, and experts, and everybody encourages one another. Every staff member is a certified personal trainer (each with multiple certificates) and each one is certified through a different school and specialty. This vast expertise makes Tenacity very unique. Come to tenacity for a good lift, cardio session, personal training, or MIT class and you’ll leave here being appreciative of a good workout and thankful for everyone you’ve met there. You won’t be disappointed!

Fantastic experience: Ive worked out at many other gyms and Tenacity is by far the best gym in the area. The family friendly atmosphere is a welcoming and motivating place to workout. You can weight train independently or take the MIT classes for an amazing workout. I love all of the cardio options too! Tenacity coaches are professional and knowledge. It’s important to have someone helping you train correctly, as I have injured myself many times before training at Tenacity. I love this gym and will never go anywhere else. Nice equipment, great vibes, and awesome coaching!

Fantastic experience: Tenacity Fitness is a gym like no other. From the moment you walk in the door you will feel the difference! Owners Steven Schaaf and Bill Jack will greet you by name - no member numbers here! Everyone is welcome, regardless of fitness level, age, or experience. I have been training 1:1 with Steven from Day 1, and have accomplished so much more than I ever imagined! We work together to establish goals, Steven works his programming magic, I follow his plan, and great things happen! Strength and Olympic lifts, conditioning, muscle and physique - we have done it all. Tenacity is always evolving, adding equipment, and updating classes. Tenacity coaches have a broad range of experience, come in and find one that works for you!

Fantastic experience: There is room for everyone at Tenacity - from power lifters, to cross fitters, to people just looking to improve their health. The staff is extremely knowledgable and friendly , and you can tell they really care about each person who walks through the door no matter where they are on their fitness journey. This is not the first gym I have joined, but it will be my last!

Fantastic experience: Incredible atmosphere and ownership. If you’re just a beginner at the gym or someone who goes everyday this is the perfect place for you. Tenacity offers a very clean and up to date environment that offers all fitness needs. All trainers are extremely personable and will answer any questions you may have. If you want to join somewhere that is family oriented Tenacity is the gym for you!

Fantastic experience: As someone who had their fitness journey start later in life, I wanted a gym that had some personality to it and a culture that makes you want to come in and get to work and not some chain gym. Tenacity has that in spades. All the coaches are more than happy to help you, everyone respects the gym, keeps it clean, and that makes you want to work harder and be better. I've gone through a few gyms before I landed here, and I'm never leaving.

Fantastic experience: I have been a member for about 3 years now and I really enjoying working out at Tenacity Fitness. I never feel intimated when I work out, and AJ and Steve as well as the other trainers are all very knowledgeable. It is a real welcoming and friendly community. I look forward to being a member for many more years.

Fantastic experience: I’ve had the pleasure of knowing most of the staff at Tenacity for about 2 years now and have to say they are unlike all the other gyms in the area. When you step in the door you’re made to feel welcome and a part of the Tenacity FAMILY. The facility is top notch and has everything you need from cardio equipment, machines, free weights, Olympic and powerlifting stations and an awesome Conditioning program. Can’t say enough good things about Steve, Bill, and all the coaches I’ve come in contact with. An awesome environment to train where you’re made to feel like family as opposed to just another client. Keep up the good work guys!
