Haverhill Personal Training
Hands down, best gym around. Sean is an amazing trainer who taught me the foundations of resistance training. BOOM is where I truly began to love training and feel comfortable in a gym environment. Highly recommended if you’re at any level in your fitness journey.
I have been going to Boom for over a year now, and I wouldn’t go to any other gym. Boom is always spotlessly clean, and the relative exclusivity means never having to wait for machines or weights. I’ve been receiving personal training from Sean, and I could not recommend him more. He is knowledgeable and encouraging and really understands how to create workouts with incredible results. Boom is an absolute five star and I could not recommend it enough.
I joined this gym 3 years ago after meeting Sean through mutual friends. I was 48 at the time and now at 51 I am in better shape and look drastically better than I did in my 20's. I had no idea what I was doing when I joined and thanks to the knowledge Sean has for both training and how to properly diet, I am at my absolute healthiest. There is no place I would rather be after work than here.
I worked with Sean for almost six months and was blown away at the results we achieved. I was nervous to injure myself since I was so out of shape, but Sean’s knowledge and expertise came into play every step of the way. The time he spend in making sure my body was conditioned to do heavy lifting was so appreciated. I was in the best shape for my wedding thanks to him. The gym itself is so clean, has great equipment, such a great vibe, down to the music 🎶
This was my first time ever doing personal training and starting my boxing career. Since then I’ve been going to the gym for 8 years and boxing for 7. Sean was an amazing trainer and constantly pushed me to my goals and encouraged me to keep working hard. Couldn’t have asked for a better gym!
Best place around for super-targeted fitness. Helped my mobility issues and improved my strength training. Definitely recommend if you want to fine-tune your workouts and advance to a new level of fitness. I went from wobbly to warrior within a month. Boom!
I've been going to Boom! for 1 year and a few months for personal training and with two sessions a week I'm easily in the best shape I've ever been! I came in as someone who hadn't been in the gym for several years and only had a bit of casual strength training in college. Since starting I've learned so much on a variety of topics such as important factors of a healthy diet (and powering your body for workouts), workout recovery, and movement variations in addition to how and when they're helpful. I'm naturally pretty curious, wanting to know how things work and Sean doesn't hoard secrets - he likes to teach and share knowledge, which I love because I never feel embarrassed for asking questions and wanting to know more. When I've had minor injuries or sore spots, he's always gracefully shifted the workouts to work around them until they feel good enough to work on again. The sessions are challenging but not unreasonably so and there's lots of variety so it's hard to get bored. The other gym-goers there are kind and respectful; it's a supportive environment and it's been great getting to see them all progress too! Would highly recommend if you're looking for a tailored program or even just searching for something different. I'm super grateful for having chosen Boom! and Sean's guidance and coaching!
Boom has made me a better person physically and mentally. Sean's expertise in training has helped me complete achievements I've never done before in my 6 years of lifting. Due to medical reasons I dropped almost 30 pounds and was struggling to get back to my weight of 160lbs. Went to boom at 131lbs and am now 7 months into the program and am weighing roughly 142lbs. No doubt I'll get there with the help of Coach Sean. BOOM!
I’ve been with Boom athletics for one year and I can easily say this is the strongest I have ever been in my life. I participated in college athletics about 10 years ago and really missed the structure and community once I graduated and was never able to focus on my strength the way I wanted to on my own. Working with boom athletics has given me the knowledge, confidence, structure, and community I was looking for. This gym is small, private, and has a great vibe. The progress I’ve seen with just 2 sessions a week over the last year has been phenomenal! Highly recommend!
First started off as a member of BOOM! Back in 2013 when I was in high school,training for football and getting ready for my senior year and for the college level. Gained a ton of lifting and workout experience in my time at BOOM!. Mean while reaching my goals on getting fast, stronger and bigger before my senior year and again before going on to the college level. Now I'm back as a trainer working at BOOM and taking what I've learned from my past experience here and everything I've learned from my time away at college. Great place to be, grow, develop and better yourself! Friendly community of people all here to help support and push you when you need it the most! BOOM!
Great atmosphere! Been coming here for over 1 year. Sean is very knowledgeable and tailors workouts at your personal level. It's a stress free gym where you can work out at your own pace with structure and guidance every step of the way. Strongly recommended!!
I have been working with Sean for about 9 months now. He is so knowledgeable, intuitive, patient, and most of all, he knows how to get results. I came to him 4 years after I broke my femur in a skiing accident. By anyone else’s standards, I would have been considered fully recovered. But, Sean knew I could be better. My injured leg was weaker and the muscles were far less defined than my other leg despite my efforts to strengthen it on my own. It’s taken a lot of split squats, but I can see and feel the massive improvement. I would have never been able to achieve this on my own without Sean’s support and encouragement. His positivity and passion is contagious. Highly, recommend Boom Athletics to anyone young or old who wants to be the best version of themselves. BTW, I’m 66 years young!
I’m so glad to have found an amazing supportive environment. Being at Booms I now have goals for myself. I love walking in and seeing everyone consistently working hard with a smile. Great place to be. I would most definitely recommend to all.
Boom athletics is just what my 11 year old needed. Motivation, confidence and a proper way how to begin his fitness journey. Sean's hard work and dedication is apparent with my sons increased athletic ability this year on the field and confidence in the classroom. Highly recommend
I call this gym my “ church”. It’s hard to put down in words what Sean and this gym bring to the table. There’s a true sense of community and family at BOOM. Everyone is consistently showing each other encouragement and support. Sean is by far the most knowledgeable trainer I’ve ever worked with. The progress I’ve made in just 6 months is undeniable. Im lifting weight I never thought imaginable and learning new things every week.
Boom is amazing!! Sean creates awesome workouts and guides you through everything so that you are never left questioning if your form is correct. He is super positive and the environment at Boom is nonjudgmental and motivating. The facility is always super clean. Since starting at Boom I have gotten significantly stronger and more knowledgeable about weight lifting in general.
I had the privilege of working with Sean at Boom Athletics for about 7 months. By far, the best gym I have trained in. I started with personal training to prep for the fire academy. Sean worked with me towards my goals and was considerably stronger in a short period of time, not to mention lost about 15 lbs. very quickly. I then transitioned into the group workouts once I started to have an understanding of the exercises and routine. Sean continued to be attentive, personable, and an incredible coach. I learned more about fitness and weight lifting in those 7 months than I have throughout my life. Sean is extremely knowledgeable about a broad range of topics, and really is able to break down some complicated theories and explain all aspects of what he is teaching. The facility is top notch— clean and well maintained. Sean has really got his program down to a science, making it easy to focus on the task at hand— getting stronger. Highly recommend Boom Athletics to anyone looking to get in shape, stay in shape or get stronger!
I have been going to Boom and working with Sean for 5 years. Sean trained me throughout my entire pregnancy, customizing a routine for me and has continued to work with me during my postpartum journey. Sean is extremely knowledgeable and the best at what he does. Boom has a great atmosphere and makes working out enjoyable - I have made many friends over the years!
Sean is the real deal , very knowledgeable and passionate. Always a great workout!
Boom Athletics is leagues better than your average gym! Boom's Facility is a comfortable training facility where you will receive premium Coaching for fantastic prices. You will train directly with the owner of boom, Sean. Sean offers private classes and group classes, in the group classes, sizes will vary depending on the time of day you decide to come in!
So glad I found this gym! I’ve been going for the last 9 months and actually look forward to working out. Sean is very knowledgeable and has helped me with strength training, which been so helpful for my overall health. If you need a gym and you’re local, Boom is the place to be! Everyone who works out there is great and super supportive.
I put five stars because Boom Athletics is getting me where I want to be in life which is fit and strong. So I can live a longer and healthier lifestyle with also lifting in the right way with the right technique. Sean Seaberg is the Person for that because he has done sports for most of his life and knows how to push yourself to get stronger but also with doing the workouts the right way so you don’t hurt yourself working out. Finally Sean Seaberg changes up the workouts constantly every time you go so that you work on different muscles every time you do a workout. I really think that Boom Athletics makes you feel welcome and everyone treats each other with respect and kindness and I think that makes a gym a great place to workout and Boom Athletics to me is the best gym for anyone that is serious about getting into a good routine workout, lose weight in pretty fair amount of time or to just get stronger. I think Boom Athletics is the best gym I have been in.
Boom! Athletics has been a great place to go and get stronger. I really enjoyed how the owner Sean has everyone go through the same fundamental sessions to ensure everyone is on the same page regarding movements, exercises, lifts, pace, etc. He does an amazing job at personalizing everything to fit your capabilitiy and giving great advice and alternatives when needed. His knowledge of the body and muscles groups is amazing and he always know how to help you improve in areas that may be tight or lakcing. I feel stronger and better overall with my body thanks to Boom! Athletics. I highly recommend this gym to anyone who is looking to better themselves in a judgement free zone that was created with care and expertise.
We’ve had our 11 year old son seeing Sean now for just about 4 months to help him move better in lacrosse and the improvement in his game is incredible. He has so much more confidence, energy and drive. Even other parents whose kids play lacrosse with him noticed a huge difference in how he moved. My son was so excited to tell Sean that he doesn’t get winded anymore by the end of the game and that he has so much energy!!! So much so that my 14 year old wanted to join. He’s been for just about a month and absolutely loves it. I can’t wait to see what the next few months bring for them and how much stronger they both will get. Sean invests his time and knowledge in teaching these kids hard work and perseverance and I know this will stay with them for years to come.
Boom is awesome! Sean is a great trainer with a lot of knowledge. I have been going to the strength classes and the striking classes, both are great. The gym is very clean and equipment is top of the line. 10/10 highly recommended the Saturday class.
I’ve been going to Boom for a little over 3 months and I’m already seeing better results than my last gym that I spent years at. Strength training is exactly what I needed and I’m so glad I found Sean to help me fulfill my potential. He’s a great trainer and the atmosphere and clients at Boom make it a fun place to workout!
Been coming here for 5 months now and have seen amazing results - not just aesthetically but all around health and strength. Sean as a trainer is incredibly professional and takes the time to give attention to you and your goals. And as a woman that has felt creeped out/unsafe in other gyms, Boom is safe, welcoming, and encouraging. If you've thought about giving it a try, do it!
Sean is a true master of his craft. Taking the time and personal attention needed for a beginner like myself to help me reach my fitness goals. 15/10 would recommend
Great gym with knowledgeable trainers. Suitable for all ranges of fitness level/ages and experience, doesn’t matter if you’ve never touched weight in your life or you’re a pro athlete trying to improve your performance/ trying to recover from an injury. I have gained long life skills from this place and will forever be grateful. Life changing experience for sure.
Sean at Boom! Athletics is fantastic! Not only will he develop a personalized plan for your fitness goals, but he will constantly challenge you, work around injuries, and accommodate any needs you may have. Sean maintains a large amount of his focus on his clients' well being; much of which includes making sure all exercises are done with proper mechanics. Many other facilities choose to focus on being money makers and they don't have the same care or personal touch that Sean has. I have and will continue to personally recommend Sean and Boom! for anyone who wants to improve their fitness levels and overall strength and well-being. I appreciate the diversified, yet personal approach you can't get at many other facilities. I also appreciate the time that Sean has taken throughout his career to educate himself in areas of mixed martial arts, nutrition, & yoga.
I trained with Sean for a few years until I had to move away from the area. Sean was by far the BEST trainer I have ever worked with. He is highly experienced, extremely knowledgeable, and most importantly, safety conscious. Training is always geared to your specific needs, abilities and goals . He seems to know just how far to push you to meet those goals, that I could never seem to accomplish on my own. I gained confidence and strength, and felt my very best during my training with Sean. I highly recommend Sean if you are serious about your health and want to feel and look your best!
Boom athletics is a great gym. Whether you're an athlete trying to up your game, someone rehabbing from an injury, or someone just getting into working out, this is your place. The acceptance and camaraderie you feel is out of this world, no matter what your level. Sean Seaberg is a wealth of knowledge and is able to cater to anyone's needs or goals.
Boom is a great gym! I gained not only strength but knowledge. It has small group classes where you get to enjoy interacting with others but also get the 1 and 1 attention. Sean is a great trainer that makes sure your form is on point and very knowledgeable. Switches up the routine so that your body doesn't plateau. Help you challenge yourself while keeping your safety first. Workout challenges are my favorite helps me push my myself to break records. I would recommend this gym to anyone who wants to lift and make gains.
Sean is a great coach with the perfect facility to get the results you want. Whether you are seeking to improve your athleticism for your specific sport or just looking to become the healthiest version of yourself, Boom! is the place to be!
Boom Athletics has been an awesome experience for me from the high quality diverse training, group classes and cleanliness of the facility.
Boom gives great attention and individual training! He will help you reach your goals no matter where you are starting from.
Sean is great at working with everyone on an individual basis and getting to know each persons weaknesses and strong points to get you strong safely. There is something at Boom! for everyone.
Sean is an amazing trainer! My 14yr old son wanted to become stronger and resilient by working out. Sean has been training us both for almost a year, and we couldn’t be happier! Sean articulates safe instructions, body awareness/ alignment and maintaining control throughout our sessions. Trusted, he is someone who encourages you to reach your goals. A gym that is a community of friendly people that support each other’s growth. If it’s a gym to commit to it’s Boom! Athletics! 100%
Sean Seaburg is amazing! He has helped me achieve multiple goals with working out and toning my body and I couldn’t be more happier! Sean and Boom Athletics are the best!!!
If you have goals u want to reach Boom is the place to be Sean is the most engaging trainer I’ve ever worked with not to mention he’s one of the most genuine people ive ever met
Sean was referred to me from a close friend who raved about his individualized and challenging programming. He started with a consultation to get to know me and my history, as well as the interests I had in conditioning and strengthening my body. Sean truly takes the time to connect with his clients and makes your workout fit you and your needs. When I moved, Sean even set up a long distance consultation and workout plan so I could continue to improve myself outside of his gym. Honestly the best place!!
The facility is clean, equipped, and the coaching is awesome. Sean is a top tier coach. He communicates the workout clearly, is respectful to everyone, and is not afraid to push you to achieve your goals.
Started coming back in November after finding Sean Seaberg and Boom Athletics and it’s been an awesome journey so far. The value is unbeatable. Sean is an excellent trainer! Patient, personal, extremely knowledgeable and will help you achieve your goals while challenging you along the way to help bring out your best. He had helped me achieve my gold with getting back into shape and I’ve seen some great results so far and plan on continuing my fitness journey here. The community in the gym is friendly, welcoming and all around very positive! Sean offers a variety of classes and funds a way to make the fun and engaging while still challenging. Sean is much more than just a trainer and I’m happy to be here!
Sean is OUTSTANDING.... for an older guy, I had gains I never thought I would... The workouts are well thought out, dynamic and highly effective. Sean is also one of the most intelligent, well spoken, kindest people I've come to know. You can't go wrong here
Sean has been rehabilitating my shoulder after a serious injury. For the first time in years I feel strong again. His process works 100 percent . Anyone looking for a good rehab and strength training coach Boom Athletics is the spot.
I was extremely impressed with the level of professionalism Sean, my trainer, exhibited while at the same time making me feel at ease and able to have a good time. His ability to read my body type and tailor my exercises to fit my needs was honestly surprising. I’ve worked with a few different trainers but he just knew how to get my body and mind to perform better than I’d been able to do before. I definitely recommend this gym
The perfect spot to really enhance your lifting and training! The trainers can handle all styles and help you get to where you want!
Sean Seaberg has helped me achieve many new goals in my fitness, constantly. I have been working out with Sean for almost 5 years now, and he has helped me with my eating habits and my form with weights. He has helped me achieve strength and conditioning goals I never knew I could. I have gained so much self esteem and results! Sean is very accommodating as well, I have a high demand work schedule that's constantly changing, he is always bending to my needs. I would recommend Boom Athletics to anyone that needs to make a positive change in their life.
This is by far the most valuable gym I have ever come across. As a former athlete and now actor, I came in having specific goals: look, strength, and rehabilitation. My expectations for this gym and Sean’s program has gone far beyond my expectations. I have been experiencing immediate results: building my strength back to my college levels, both building lean muscle and shedding excess fat, and drastically improving my capabilities around my college back injury. This is the most intimate, hands on gym I’ve ever been a part of, which IS NOT reflected by the cost. Sean is extremely knowledgeable, personable, and will be sure to stinusmte your mind as much as your body. I have full trust in Sean as my trainer, but also as a good friend! Highly recommend!!!
BOOM! I CANNOT say enough about this place! When I first starting working with Sean, I was just getting into fitness and wasn't very sure of myself or what I was doing. But within the first couple of months I noticed SERIOUS results. Sean is an exceptional trainer and just a fantastic guy to work with and be around. As an aspiring trainer, I could not have asked for a better mentor. So no matter what your fitness goals are, BOOM! is the place make them happen!
I’ve been a member here over a year now and the gym is great for any level. Sean is the owner/trainer and provides personal workouts every day you’re there. Takes pride and care in your personal well being inside and outside the gym. He provides a multitude of classes and sessions and is flexible with hours to meet anyone schedule (I work 10-11 hours a day on average). He had worked with professional athletes and beginners with no gym experience. I recommend this gym to everyone looking to improve their health, fitness and quality of life at any level.
Sean is the man. He is knowledgeable, intuitive and motivating. He puts you through the grind and makes it fun.
Great place to work out! I've been going to Boom for about four months now. As a firefighter I need to stay in shape to do my job effectively and safely. Working out has been a big part of my life. Going to Boom takes me up another notch. Sean is very knowledgeable about fitness and the human body. He always has an open ear to questions. I would recommend this gym to anyone.
I have been working with Sean Seaberg for almost a year now, and it has been a game changer in my overall fitness goals. Sean is a highly engaged trainer and overall good guy. He takes time with each client to make sure we are accountable and achieving our goals, all the while making it fun experience. As for the facilities, they're clean and have all the modern fitness and strength training tools one needs to make their goals come to life. It is a great community of people and I highly recommend that if you're looking for a challenge check out Boom Athletics.!
BOOM IS THE BEST ! I have been going for a year now and love it ! Sean is the best trainer by far, he takes the time and energy into everyone there . The workouts were always great , and I really learned proper technique from all the trainings. I couldn’t be any more satisfied , so happy to be part of the Boom family !!
Sean is a great guy and really knows what he is doing. overall he provides a very safe environment to get in shape. I have experienced multiple injuries in my life that sometimes effect the way I have to approach working out. Sean does a great job of coaching me through correct form to ensure I can properly get back in shape without further injuring my self and I still walk out every time feeling like I still put in a lot of work, which is very hard a lot of times when dealing with old injury's..
If you are experienced, or just beginning Boom! Athletics has everything you need. Sean is easily one of the best coaches. If you show up with a positive attitude and are willing to work, Sean will get you the results you are looking for. Personally for me, lifting weights was something I had always wanted to do but I was always afraid to even step foot on the weight floor, instead I stuck to what I knew which was running on the treadmill and stepping on the stair master. From the first class I took, Sean made me feel comfortable despite feeling reserved. 6 months later, I am proud to say I am comfortable to through some weight around with knowledge and confidence. The space is clean, and the atmosphere is friendly, it really is a supportive community that is fun and interactive. If you are looking for quality, BOOM! Athletics is where it is at. I wish I had joined sooner! Thanks Sean!!!
Great personalized work outs and coaching at a great price point.
Training for a sport is a big deal for me. I needed a place where I can learn the proper way how to lift, stay fit, and be on a well balanced diet. Boom! Athletics has a top fitness program that has improved me as a runner being more explosive and stronger. I’ve been going there for a little bit over 6 months and the results i’ve gotten are outstanding. Boom! Athletics fitness program is affordable and is based on your scheduling. It’s also in the heart of Haverhill and is an ideal program to anyone! I recommend it to everyone!
Boom athletics is one of the best gym I’ve been to in Haverhill. The trainers are very charismatic and pay very close attention to detail when it comes to form. If decide you decide to know be ready for a quality experience
I've been working with Boom! Athletics on and off for a few years and whenever I'm going consistently I can see progress very fast! It's the best quality of strength and conditioning in Haverhill, easily. I was a former gymnast & coach. I had multiple surgeries including both shoulders and elbows. Sean was able to help me grow physically and getting me back on track doing what I love once again and then some. If you're looking to get your fitness on this is the best deal anywhere!
A few months ago, I was new to the area and looking for a gym. In every city, there are the typical $10-$40/month corporate gym options. You can go in, do what you need to do, and leave - without ever having to speak to somebody. That’s okay. People do it. And sure enough; I was close to doing it all over again. Then I found Boom. And I’m so glad I did. Boom will push you. It will engage you. It will demand you interact with others and yourself. But I promise you: if you are getting tired of trudging through the aimless, goal-less, cookie cutter gym routine and want to take your fitness to the next level, Boom is, without a doubt, the best bang for your buck. The gyms owned by Sean Seaburg, a local Haverhill guy, and he’ll personally work with you to identify and achieve your goals. After spending just a month with Sean, I’m so glad my money is going to his business and back into the city of Haverhill. Seriously - one of the best kept secrets in the Valley. If you want a higher fitness awareness; knowledge, and engagement, at least visit Boom and consider its model. I’m so happy I found it.
Such great energy and positivity. Boom athletics is the place where you want to make a change for the better in your life. All trainers are experts and have such caring qualities. One of the best decisions I’ve made!
I've been seeing Sean for almost 3 years now. Ive been dealing with a bunch of different injuries from poor form while working out by myself, but he was able to work around every single injury I've had and corrected my form. When I first started seeing him I had a bulging disk in my L5 S1 disk. The pain in my lower back made it hard for me to do certain exercises like squats and deadlifts, but after a few months the pain went away and I was squatting 240 like it was nothing. I've seen tremendous gains since I've been with him he always pushes people to be the best they can. The environment is better then any atmosphere I've been in. Sean is more than my trainer, he's my mentor and one of my best friends. I highly recommend him to anyone that's trying to strive to be the best person they can be
I’ve been going to Boom for a few months now. As someone who had no idea about weight training, I’m learning something new every session and my body is transforming as a result. This is by far the best bang for your buck value you can get from any gym or fitness center.
I’ve been going to Sean for almost 2 years! Before going to him I was scared to pick up a barbell or go near the weights, but now it’s one of my favorite things to do in the gym! He has helped me achieved so many of my goals and the gym atmosphere is great! Boom is awesome 10/10 recommend!
For all you 50+ year old men whom daydream of the fitness strength and stamina you possessed years ago, before the family took precedence over your personal well-being, this is the place to get it back! I like many, have ping-ponged through the local fitness centers and their rotating trainers with no success. A friend suggested I check out Boom Athletics. Wow! Felt the difference upon first session with Sean. Over the past several months, I've come to appreciate Sean's care for his clients as we all work towards our goals. As others have pointed out, his knowledge of nutrition and training is unprecedented. My strength and stamina have increased ten fold in six months. But, what makes Boom Athletics 'the choice' is Sean's personal attention and care. He has not just created the best facility in Greater Haverhill area, he has created a supportive home for his clients. There's no loud music, no headphones, no over-the-top outfits....there's clients happy and supportive of one-another making progress towards their personal goals. Do as I did. Check Boom out. Follow Sean's guidance. Enjoy looking and feeling GREAT!
Extremely professional and knowledgeable. Great gym and owner.
In the past I have gone to large gyms and worked out at home doing workouts such as P90X. I never had much guidance in the gym so I found it hard to stay motivated. Working out at home got dull over time. I had great results working out at home years ago but watching the same DVD's over and over got to be repetitive. I found out from a co-worker that Boom Athletics was up on the 5th floor from where I worked. I decided to stop in one day after work and Sean gave me a free training session. I have been stopping by his gym now for several months, Sean is great to work with and always mixes up the routine. Typically most people will come in and do a warm up and then he will have everyone do exercises that work a specific muscle group - legs, back, chest etc. The classes are small and really only consist of maybe 4-5 people max, everyone I have met has been helpful and friendly so it's a good environment to work out in. Sean works with people who are beginners and those that are looking for something more advanced so anyone can participate. I highly recommend checking out Boom Athletics, you won't regret it!
