Sonic boom fitness is amazing!! I’ve always heard such great things about this gym, so I decided to try out their 7 free classes at the time. Since then I’ve been hooked! Their coaching/staff are so friendly and helpful! They have helped me so much physically and mentally so far and I can’t wait to keep coming back! I highly recommend Sonic Boom fitness!

Very friendly place, You feel welcomed by everyone and the workouts are great!! I would definitely recommend.

I just joined at the beginning of January and it has been the best experience, I was welcomed with open arms and everything has been amazing!!!

Community atmosphere with highly engaging coaches.

Chris Mezzaroba is a kickboxing coach at Sonic Boom Fitness. Since I’ve been going to Chris’s classes, I’ve lost 40 pounds, and I’ve kept it off!! Chris makes the classes fun yet challenging. He develops new programs every class, and pushes us to keep up. I plan to continue with Chris in 2024 and beyond! He is awesome!!!!

I love the classes at Sonic! All the instructors are great to work with and really help give you the push you need during classes! I did a 6 week boot camp and lost weight and toned up a lot!

I only started at sonic boom fitness a few months ago and already I feel and look so much stronger. I felt welcomed since the first class. Everyone at the gym is encouraging and motivates you to do your best. Whether you’re a beginner or more advanced, the knowledgeable staff here will help you achieve your fitness goals. I highly recommend

Best gym all around on the planet trainers are great. I could say so much more but there no reason to results speak for themselves

Gym is the best around for overall atmosphere with the open arms welcome from the owners, coaches, and fellow members!! Their 3 years running as best fitness center is a prime example!!

This gym is amazing. The coaches are top notch- challenging you daily, encouraging everyone, no matter your level. Modifying when needed but also pushing you to be better then the day before… Class participants are welcoming and supportive . I cannot say enough good things about Sonic Boom. It’s a wonderful gym family for me.

If your looking for a gym that keeps you motivated and accountable this is it. The coaches are knowledgeable. The workouts can be modified to your fitness level. The members are welcoming and encouraging and the music is always on point ! I would highly recommend checking them out and becoming part of the best gym fam around !

What an amazing gym! The owners/coaches are always there helping members , encouraging and cheering you on. They make each class fun but challenging, the push you to be better and are rooting for you every step of the way! The members are like family, welcoming and friendly!

Sonic Boom is more than a gym. It’s a family. Everyone is friendly, welcoming, and encouraging. All of the trainers are great and helpful. It’s a great place to work out!

Great place to get started in your fitness journey or continue something you’ve already started. Great coaches and community. Highly recommend.

Great workout environment, challenging yet achievable workouts, the coaches are friendly, approachable, and helpful. Great place to start or continue on your fitness journey.

I have done virtual coaching with Vito previously and he holds you accountable. He also listens to your likes and dislikes to customize a program specifically for you

I started Sonic Boom Fitness about a year and half ago, with little experience and slightly intimidated. That quickly faded when I was not only welcomed by the coaches but the members as well.

Sonic Boom Fitness is the best! I have had nothing, but good experiences since I joined last March. Vito, Steve and Mike are high energy and encouraging through each class. They gear workouts towards your goals and are always offering fitness advice. It just so happens the members are amazing too! If you are looking to try a new gym, Sonic Boom is definitely the place to be!

Sonic Boom is the best gym i’ve ever belonged to. Coming up on three years and it’s the only gym i’ve ever been able to stay consistent with. The instructors are the best, the other members are welcoming, and the owner genuinely cares about his members. Give it a try, you won’t regret it !

Sonic Boom has a family kind of feel. When you walk in, you know you are going to have a good time, even if there are sled pushes or burpees involved. Vito is a fantastic personal trainer!

It has not only changed how I feel on the outside but the inside too. The coaches are the best people. They motivate you, keep you focused, and always celebrate your wins! I’ve never felt out of place or uncomfortable at this gym for that reason and many others. Additionally, every member is on a different ability level- with that being said, the coaches modify and support every single person through every workout. Nothing is too big, and nothing is too small. Everyone is capable to make this a lifestyle- a day at a time. They believe it, and eventually you do too. You become a part of a community at this gym- a family. I’m forever grateful for SBF! I can’t wait to see what this next year has in store. Less

Great gym to be apart of. Awesome community of members ownership really makes you feel welcomed and are always trying to help you get to the next level and offering great ways for members to hang outside of the gym which helps give that family feel !

I can't say enough great things about Sonic Boom. Steve, Vito, Aimee are aces. No nonsense, no attitudes and helpful people !

Absolutely love Sonic Boom fitness, I have been a member since May and I am always getting results! The coaches and people there are amazing! I am always telling people to come Join!

This gym really is like no other. I have found much more motivation and excitement in my fitness journey! The members here really push each other to be the best versions of themselves. Recommend to anyone who is struggling in their workout routines, fitness goals, and overall wellness.

The members support and push each other to succeed. The amount of class times they have can fit anyone’s schedule so if you’re looking for a great gym with great coaches and workouts this is the place.

Great gym with a nice variety of class options throughout the day. I love kickboxing! The instructors are motivating and make classes exciting and fun. I appreciate the opportunity to step outside my comfort zone and learn proper techniques.

I’ve been a member at Sonic Boom Fitness almost 2 years now and have belonged to several gyms prior. This is hands down the best atmosphere and I have reached many goals since I’ve been here. Everyone is helpful and encouraging, the coaches and trainers are top notch and really want to help you meet your goals!

Best Gym in Delco!

I have been at sonic boom for almost 2 years now and am so happy I started. Since the beginning everyone has been so encouraging and the coaches are very knowledgeable. Since starting I have come out of my comfort zone and recently started lifting heavier weights and doing moves I would never think to try before.

I’ve been at the Boom for almost 4 years and I can honestly say I’ve never been in better shape, had a better mindset, and have tried more things that I would have never imagined in my life!! The coaches and my 5am friends that support me is what keeps me going! I can’t thank Sonic enough, you’re missing out if you don’t give them a chance, it’s life changing 🙌🏻

Sonic Boom Fitness has been the key to keeping my health and wellness goals consistent and fun. The environment, the people, and the trainers are why Sonic Boom has been voted one of the best gyms in Delco.

Before joining Sonic Boom I was never motivated to go to the gym or workout, now I try to get to the gym as much as I can. I’ve lost over 30 pounds, have added muscle and toned my body with the help of Sonic Boom. The coaches are there every step of the way to motivate you and modify the workout if you’re not quite there yet. I can’t recommend this gym enough!

This is more like a family than a gym, everyone is so supportive no matter what level of fit you are at! The coaches walk you through and give you modifications so you can get the most out of every workout. I have achieved some personal goals of mine with the help of these coaches I’ll never go to another gym.

I have now been a member for about 2 years now and still can’t say enough about how grateful I am for the coaches helping me progress day after day and help answer any and all questions I have. Best gym around!

The best gym ever! The coaches and all of the people that go there are so positive and welcoming! This is the only gym I have been able to stick with for a while. I’ve made so much progress ever since I started I’ll never go anywhere else!!!

Vito is GREAT! He responded to my inquiry within minutes and answered all my questions. He provides excellent training and I highly recommend him and the services!!!

The energy here is unmatched. Great place to workout

As someone who has struggled with nutrition and working out most of my adult life, I definitely have found a home at Sonic Boom Fitness. Absolutely love this gym, our coaches and the members. Doesn’t matter your age or size, you will feel right at home!

I was scared at first because I was extremely out of shape. The trainer gave me a great workout and told me to go at my pace and brought out the best in me. Truly a great gym. I recommend it to everyone!

I can’t recommend Sonic Boom Fitness enough! I’ve never been one to stick to a routine or even enjoy going to the gym but since joining Sonic Boom in January I rarely miss a day. Vito, Steve, and Matt are all amazing coaches and are there every step of the way to help you and even modify the workouts to your fitness level. If you’re looking for a new gym give them a try

Steve, Vito and the entire crew of Sonic Boom has the heart, dedication and commitment to making you better every day. I can't say enough good things about our experiences at Sonic Boom

Now I’ve never been overweight for my body but I hated what I seen in the mirror and my Toxic choices I was choosing for myself. I walked into for my first intro beginning of December shaking like a leaf ready to leave never have stepping foot into a gym before, to now consistently going 5 days a week and it being the best part of my day. Sonic Boom has seriously changed my life and I’m so thankful for the support, push and the welcoming I get every time I step foot in there. I just recently completed the 6 week challenge, and for me it wasn’t about the weight loss but the push, nutrition information and being held accountable and showing up that I needed. I now feel like I have a little family there and I’m now a lifer! I lost inches in my waist, hips and thighs and my arms grew! (Finally getting that arm muscle going!) Nothing feels better then gaining strength, knowledge and self love! 💪🏼💪🏼 Less

The moment I walked in it felt like home again!! Every one is great, Matt, Vito and Steve and of course Mezz and the rest of the kickboxing coaches!!! Love it and will definitely be staying

I love this place. The coaches are the best. They make the classes a lot of fun, while also pushing you to do your best & reach for new goals.

These guys don’t give up on you while also not pushing you too far. It’s a very fine line, but they manage it perfectly. You WILL get results, and all you have to do is show up and do the work.

dedicated coaches, great class sizes, and guaranteed to be a great workout 💪🏋️‍♀️👊🤘

Awesome gym with great instructors. If your looking for great work outs and good instruction look no further.

This gym has changed the way i feel about working out. I am more confident then ever and I’m getting stronger everyday. The workouts are always different which makes everyday better then the next. The trainers are the absolute best and they always push you to work harder. The classes and all the members make working out something to look forward to. I love SONIC BOOM. I’ll never choose to go anywhere else. Less

Best gym ever!! The owners are super helpful and the workouts are incredible.

Good energy, diverse workouts, supportive trainers and community

One week in coaches are great atmosphere is awesome 😎 I love it my new home.

These guys are the best....I have never been this dedicated to a gym and I’m going on 3 Years here!! The atmosphere is inviting, challenging and most of all fun! It’s hard to find a gym where you walk in and just feel welcomed and accepted. No matter what your fitness level, this is the place to be because these guys care, are knowledgeable and offer something more than any other gym in Delco. ... More

Excellent gym! Very different from what I have ever done. The trainers create the work-out for the day and then they help you execute the exercises properly and encourage NOT pressure you to push yourself! I really needed someone to motivate me and this is exactly what they do. Love it!

Incredible gym with an amazing community of members. Vito goes out of his way to help every single individual whether it be nutrition guidance or exercise form. Great place!

I've been a member at Sonic Boom for almost two years now and I absolutely love this place!

I highly recommend this gym to anyone and everyone! Less

I have had memberships to many different gyms over the last 5 years and seemed to keep switching..this is the only gym that has everything I want. They offer classes, open gym, and also personal training. I can't say enough about the atmosphere here either, you will not just be another face in the crowd here, the guys who own and run the gym really care about helping you achieve your goals.

Awesome coaches and environment! They really care about their clients!

This is the best gym I’ve ever joined! The coaches help everyone individual with their goals. I’m the strongest I’ve ever been! If you haven’t check it out yet than you’re missing out on great life changes.

Sonic Boom is by far the best gym in Delco. I joined Boom back in May and I couldn’t be happier that I did.

Not to mention everyone at the gym is so friendly especially the coaches. Either Vito, Steve or Matt are always by my side throughout the workouts and thats what I love most about the gym. I no longer have to guess if I’m doing the workout right and they are always pushing me to be my best. If you’re nervous about joining due to lack of fitness knowledge the trainers are able to scale the workouts to what you can handle. I highly recommend you join boom, you won’t regret it! Less

I joined Sonic Boom a little over a year ago because my friend was a member. I needed an atmosphere that I could bring my baby with me at times. It was the best decision I made.

I joined Sonic Boom a little over a year ago because my friend was a member. I needed an atmosphere that I could bring my baby with me at times. It was the best decision I made. I am currently the strongest I have ever been and pushed to limits that I never thought was possible. The coaches are so friendly and always go the extra mile to help with all of your fitness needs. They even entertained my little guy at times so I could finish a class! Not only are the coaches great, but so are the members and I have formed new friendships. Best gym in Delco!! Less

This gym has really taken my fitness to the next level!! The coaches are supportive and push you at the same time! Just keep showing up and the results are endless!! None to mention the price is sooo reasonable for what you get!!

Great gym with very knowledgeable Coaches who help me work around my injuries. I felt like I was in a rut with working out and needed a change from the regular routine. After the first workout I was hooked.

Sonic Boom is the first gym with classes that I’ve ever joined. This summer will be a year since I’ve joined. I’ve loved it so far. The classes push me way more than I can ever push myself. I have felt myself become so much stronger. The instructors ensure that you understand the workouts & perform the exercises correctly to prevent injury. It’s been an awesome experience!

Fantastic gym, The Guys there have changed my strength, endurance, and Metal toughness. I’m glad that I chose to join.

I started at Sonic Boom when they first opened in Springfield. It has been one of the best experiences. The coaches have helped me get outside my comfort zone and push myself beyond my limits. I worked out during my recent pregnancy and they helped me modify movements to keep it safe and comfortable. I look forward to walking in there and knowing I will see friendly faces and get a good workout.

I have never been a fan of gyms in general but this place becomes like family and you get to workout and make memories. 5 stars everyday!!!!!

This place is way different from any gym I’ve ever been to. There are people of all ages and the owners really take the time to get to know each member. You can tell they really care about their members. It’s like a big family all there to support each other. Whatever your goals may be. I have developed a love for lifting and can’t believe how far I have come in a year.

If you are looking for a gym where the coaches care about you and is a family environment, this is your place! The coaches are extremely knowledgeable, push you to do better and strive to make you better. I would highly recommend this gym to anyone: from no workout experience to an athlete!

Sonic Boom Fitness is without a doubt the best gym in the area. The owners/coaches are knowlegible, friendly and able to work with and motivate anyone. The classes are no nonsense and a great workout for anyone regardless of your fitness level.

How can I put into words how much I love this gym and the 3 amazing gentleman that own it? I have been working out at Sonic Boom for 3 years. I am by no means a fitness buff or even an exercise enthusiast. I have my struggles with keeping myself motivated and they are there for me every step of the way. They will check in when I take a hiatus and receive me back with open arms and zero judgment. ... More

I am by no means a fitness buff or even an exercise enthusiast. I have my struggles with keeping myself motivated and they are there for me every step of the way.

It has been a pleasure watching them grow both personally and professionally during my time with them. There is something for everyone at this gym. The hype is real. Really Real. So get there. Less

There are no excuses to not work out here; classes start at 5am and while we might not all be thrilled that early in the morning there is never a day I don’t leave feeling great! Starting is always the hard part but once you do the coaches and members at Boom will make sure you keep moving forward and reach new goals ! Less

Since I’ve moved from the area, I haven’t been able to find anywhere matching anything like the environment or support they’ve established at the gym.

From the jump the staff and the members were super welcoming when it came to us being new members. Matt, Vito, and Steve who are the coaches are super motivating and encouraging in and out of the gym. I have done multiple weight loss challenges that the gym offers and throughout the whole entire challenge I would receive motivation, support, and tips to keep me on track! No matter what your size, age, gender or athletic level the coaches do a great job at adapting a movement or exercise to make it fit best for you! I highly recommend sonic boom if you are looking for a change up in your workout! Sonic boom is where you will bust your butt during every workout but still have a good time doing it! Less

Whether you're a seasoned gym goer or a newcomer that can't tell the difference between a bench press and a front squat, the coaches at Sonic Boom Fitness have your back. A knowledgable staff focused on the same goals you have- to be the best version of yourself you can possibly become. 13/10 will lift here again

Great comfortable enviroment! Coaches really know and cater to your needs. For the price ans what you are getting you cant beat it!

Members are of all ages and fitness levels and it's really fostered this community of encouragement and support for each other. Not only are the workouts challenging but the coaches are all amazing and not only take the extra time to explain movements and ensure proper form but they push you beyond what you think is possible for yourself. They've also been a great resource for nutrition advice. I have gotten so strong since joining and they've lit the fire in me to continually keep raising the bar for myself. Try the free 3-day trial, and I guarantee it won't take long to see what a great place Sonic Boom is! Less

Sonic Boom is the best gym in the area. The coaches are so knowledgeable and helpful. They offer more classes than other gyms I have found. The classes are for all fitness levels and change daily so you never get “bored”. Other members are super welcoming making the atmosphere fun and comfortable. When you go to Boom you know you are going to get a new, great, challenging workout EVERYTIME.

Sonic Boom offers skilled instructions, amazing music :) and loads of motivation. I've never enjoyed working out as much as I have this past year. There is also something to be said for the clientele, they show up with a fierce attitude and are ready to work. Everyone gives 110%, 100% of the time. Matt, Vito and Steve, you guys are amazing and have a great business. Thank you!

I have tried a few Gyms In the Area and hands down they are the best. Amazing coaches and awesome people to work out with. They make you feel like Family. Two thumbs up. 👍👍

I cannot tell you how much I love this gym. I have been coming here for 2 years and I see NO stopping in sight. I actually get really pumped when I know I am going. I am 55 and never thought I would be doing what I am doing today. I lift pretty decent weight, jump rope, run, bike and the list goes on and building my muscles up. Before I started I was winded just climbing steps. I was headed down the wrong road with my health and now I feel amazing and not on any meds because of Sonic Boom and I am stoked about that. We are always being watched so we are doing all moves the right way. Also it has helped me mentally. If I have a bad day and really don't want to go but drag myself there I am so happy I did cause these coaches turn it right around send me off in the best mental state. They have also taught me how to eat the proper way so I am at my best. Thank you from the bottom of my heart Steve, Vito and Matt for always believing in me and making me feel so welcomed and part of this amazing family. If you are on the fence about coming to Sonic Boom don't be. It was one of the best decision of my life. Less

The best gym around! The owners and members really make you feel at home and comfortable. They work you through rough patches, cheer you on and really believe in you! I would recommend this place to anyone I speak to! All ages, shapes, sizes, sexes, etc will feel comfortable!!!

the class are for any skill level - the coaches are motivating and assist with different movements. The gym is a great workout environment.

Best gym ever. Only one I've ever stuck with. I'm so excited to go every day. Try it out you won't regret it.

Love sonic!!!!! Only routine I’ve been able to stick to in years!! Great guys !

Of all the gyms I have ever gone to, this by far is the best gym around! Great trainers and great people to workout with. They motivate you and are always their to coach you to make sure you you are doing the exercises correctly. Going to Sonic Boom is like being part of a family always motivating and pushing you to your next level!

Best gym ever!! Love my 5am crew, it is always a great time while getting fit!!

just gotta see it for yourself, words cannot explain 😉💪🏼🤚🏼

Fantastic atmosphere! It's nice to know that your trainers continue to push you to do your very best and genuinely care! Hands down one of my favorite times of the day!

Great workouts, people and coaches. Look forward to each day.

I started going to Sonic Boom last September and it has been such a great experience! I never thought waking up for a class at 5 am to workout could be so hard and rewarding all at the same time! The staff is knowledgeable, patient, and down right fun!!! #teamnosleep

I have issues with my hips and back which cause pain and discomfort. The personal trainers have been able to pin point my pain issue which relates to my mobility and have been doing strengthens and resistance exercises with me. These exercises have made s difference in my range of mobility and the wake up now pain free. Thank you!!

A great way to kick off Chritmas Eve!!! Best workouts I have ever had with phenomenal instructors.

From day one these guys want nothing but the best from you! They are patient and encouraging during your whole workout. All the exsisting members are awesome too!

Great place for a great work out with great people!

From my very first workout all of the coaches and other people at SonicBoom made me feel welcomed! The coaches take time to show you how to do exercises correctly and accurately. They have pushed me to become better, stronger, & faster in just a few short months! I love the atmosphere at SonicBoom, it keeps me coming back for more!
