Seacoast Athletics

Fantastic experience: This is my first gym experience and I couldn’t be happier with my decision. Great facility, great trainers only wish I had started sooner!

Fantastic experience: Absolutely love this place! The attention from the coaches and the encouragement from other members makes it one of a kind. The workouts, service and community are amazing. Couldn’t recommend it more highly.

Fantastic experience: Justin has been my strength and conditioning coach for the last 8 years. He’s extremely knowledgeable and gives 110% to all his clients. I highly recommend Seacoast Athletics.

Fantastic experience: I started at Seacoast Athletics 2 months ago, and I already know this is the beginning of a new long term community for me. Group classes have been the answer to my ability to keep fitness as a multi-day a week habit. I learned this for myself 6 years ago, and it remains true. After 3 lovely years chasing an exclusively CrossFit style fitness approach, I arrived at a point where it was time for change: I was having trouble with motivation, but ultimately with the frustration of reaching what felt like a rather unimpressive plateau with my abilities while feeling plagued with low key injuries more often than not. I wanted to incorporate more body building, muscle group focused training but wasn't excited about the solo, headphones-and-no-direct-eye-contact gym life, or the loss of a gym community and energy. I reached out to a friend who is super happy at SA and who was also making great progress with her goals. She put me in touch with Justin Mahan, the owner and head coach here. Justin and his coaching staff are superb. They are earnest in their determination to be the best coach for you each class. As individuals, they are each stellar, caring people. They realize the importance of community and fortify it with a welcoming, multi fitness level daily offering of show-up-and-be-fit workouts. I really personally appreciate an environment where I can let go of some past approaches to working out and begin again with where I am today. There are as many fitness goals as there are people in the gym with you at any given class. At Seacoast Athletics, I feel like this is celebrated, not confined to conform to one path.

Fantastic experience: Exceptional Gym! Very clean, spacious gym. Coaches are very friendly, knowledgeable and very accommodating! Programming is excellent! This is our happy place!! Thank you Justin!

Fantastic experience: Fantastic group of people ! Coaches and those working out. Each class gets individually tailored with personal attention. Wide variety of ages and skill level makes it fun.

Fantastic experience: I have tried a lot of gyms, three in the Seacoast area, and Seacoast Athletics is doing what the others say they are or want to do. Really. I’m 60+ and have been in better shape in my life and I decided I would try SA to see what happened. Yes, it’s cross fit, and yes there are a lot of 30+ Swinging from the rings and lifting heavy weights. Good on them. But, I and a few others, follow an adjusted path with Alex and Justin helping every step of the way. I do not feel intimidated. Really. Everyone is friendly. Really. It’s a great community! I love going to the classes and feel great when I finish each class strongly. I am on a mission now to see what I may accomplish! Try it! Really.

Fantastic experience: I love this gym! The programming is outstanding and scalable- all ages and fitness levels train here- from CrossFit competitors to grandmas getting back into shape. Huge focus on mobility and functional fitness. Justin, Lisa and his team make everyone feel welcome.

Fantastic experience: I just joined SA in July after hearing my friends rave about it…after only 2 weeks of being there, I can see why. You can tell that the workouts are very well planned, each having a distinct purpose/focusing on certain muscles or skills. The workouts have been a great combo of challenging and fun. From weight lifting, cardio, core- it’s all there in great programmed workouts- all you have to do is show up. The coaches are friendly and knowledgeable and the members have made the environment very welcoming. Happy I joined, if you’re thinking of trying out a new gym I definitely recommend SA.

Fantastic experience: Already have gone a long way in my weightloss journey (losing 150 pounds) I still felt like a beginner when it comes to exercise. I was lost when I would walk into any other gym and not knowing the proper way of doing things or even what to do every time I went. This gym is by far the best place I have ever worked out at. The people are like family, the gym is clean and very well put together, and the trainers are absolutely amazing as far as attitude and their knowledge. I actually look forward to working out now and physically and mentally feel stronger than I did the day before. Seacoast Athletics is a place I would highly recommend!

Fantastic experience: I’m new to strength and conditioning workouts and was nervous to join without any experience, but after several weeks I am absolutely loving it! It is unlike any workout environment I’ve been in before. I’m used to barre and hot yoga, but this gives me more of an actual workout, I find myself excited to go - working out has become a real treat! All the people from staff to other members have made me feel like part of the group. It’s truly refreshing and not at all intimidating(like I thought a gym like this would be). It’s really fun!

Fantastic experience: Seacoast Athletics is the answer I’ve been looking for. It had been over a year without any formal exercise when I first started at the gym but I felt welcomed and supported from day one. I appreciate the time and planning that is put into our customized workouts as well as the stretching segments at the start of each class to make sure we’re warmed up and ready to rock. In just 7 months I’ve seen changes in my strength and endurance that haven’t been achieved elsewhere. Seacoast Athletics provides tailored workouts to my level with room to grow and reach my goals. I believe I’ve begun a fitness journey that will lead to lasting results. It’s a warm community guided by experienced instructors who care about the development of their members. All the while making it fun!

Fantastic experience: Representing the over 60 group, my time at Seacoast Athletics is always welcoming. I am always greeted warmly by all athletes. I was surprised at the many age groups that are represented here and how well everyone works together to stay or fit. Strongly suggest giving it a try. A personal training session at the beginning is a great way to get to know Justin and what he hopes to do for you. His knowledge is impressive.

Fantastic experience: Seacoast is an excellent place to workout and get fit. The coaching motivates me to continue to get better and I always learn new tips to improve my skill and technique. As an older guy, it can intimidating to do group fitness and feel pressure to keep pace but you will never feel that way here. The different levels of programming within each class allow you to choose a level that you are comfortable with and participate at that level while also challenging yourself to become a better athlete. SA is clean, well run and a fun place to spend an hour or so a day.

Fantastic experience: I'd follow Justin to any gym. The amount of knowledge he has across all forms of training is priceless. Better yet, each work out is catered to what you're looking for. Some days I want to lift heavy, other days I'm just looking to get a nice workout in and keep my heart rate up for an extended period of time. Other times, I decide to run a marathon...He's been there to support any and all fitness goal I have. Doesn't matter your age or fitness level. You won't find someone that cares more for his clients. Can't speak highly enough about the other staff and members either. All around, there's just no better fitness community.

Fantastic experience: The workouts are clearly explained, different paths are provided depending on your goals and the workouts kick your butt (in a good way)! I have an issue with my foot and they are great with offering alternative exercises to accomplish the same goal. I have taken classes with Justin, Ralph and Lisa and they are all fantastic.

Fantastic experience: Seacoast Athletics is unlike any gym in the area. Owners Justin and Lisa have built a very welcoming space where athletes of all kinds are able to meet their fitness goals side by side. Seacoast Athletics' programming will challenge anyone, and the diversity of movements offered during each day and individual workout will help anyone meet whatever fitness goals they may have. The community and atmosphere are second to none. Coaches Nick, Ralph and Kayla take their cues from Justin and Lisa, and no matter who is coaching the experience is always seamless. We are lucky to be a part of it.

Fantastic experience: A 5 star review undersells the impact Seacoast Athletics has had on me. Simply put; In EVERY exercise I move better, with more strength and less fatigue across a broader range of motion. I feel better than I ever have, and have remained injury free while finding ways to accomplish things I never thought I was capable of. Yes, the gym itself and the community is amazing....but it's the attention to detail that Justin has (along with every other coach) that makes SA truly unique. I feel challenged in the workouts, but I'm also able to see objective, measurable improvements. I'm so grateful to the entire team at SA. Anyone with a fitness goal stands to gain a lot from reaching out.

Fantastic experience: If you’re looking to bring your fitness to the next level while being surrounded by great people, this is the gym for you. Justin and Lisa are great trainers with a real desire to see you become the best version of yourself. Highly recommended for all skill levels…

Fantastic experience: I am new to this type of exercise and I’m so glad I joined Seacoast Athletics. The coaches there take the time teach you how to properly do the work outs and make it fun with their cheery attitude and awesome playlists. The gym is a big open space and extremely clean, I appreciate the clean up after every workout. Great community to join if you’re looking for motivation for a healthier for active lifestyle.

Fantastic experience: Walking into Seacoast Athletics (SA), I was nervous and excited, you can imagine, right? However, little did I know, that it would become part of my daily ritual and help me rejuvenate due to my crazy schedule. It's astonishing to witness how Justin and his team empower their members while creating an engaging supportive community culture. The programming is targeted for every fitness level, better yet, you get to choose. The team pays strict attention to form and safety in order to maximize your progress without injury. They are compassionate individuals who have created a niche in the fitness community. It doesn't matter where you are in your fitness journey. At SA, it's about creating a balanced lifestyle and greater overall well-being. The first step in the door is always the most difficult, but I assure you, it'll be one of the best decisions you'll ever make.

Fantastic experience: Seacoast athletics has been a second home for me since joining at the end of the summer in 2021. The personal coaching I have gotten from Justin, Nick, and Lisa has been incredible. The small class sizes allow that one-on-one-esque interaction while still allowing the flow of the class to keep at a steady pace. I've reached new levels in my fitness journey, learned so much about form with even the simplest movements such as rowing and push ups. The community has been bar none my favorite out of any gym I've been a part of over the last 10 years. There's are so many reasons why Seacoast Athletics was voted best fitness center on the seacoast last year. And I only mentioned a few of them.

Fantastic experience: Justin and team have built an amazing gym and an amazing family. I came back after not working out for awhile and felt right at home immediately. If you are looking for a new gym, stop looking - you’ve found it.

Fantastic experience: The BEST gym around. It'll get you stronger and fit in no time. Excellent coaches who take the time to actually teach you the proper techniques to the excersises and their knowledge is unsurpassed. The people who you work out with are all great, all friendly. The gym itself is brand new, tons of equipment, meticulously clean, and has many times to choose a class during the day.

Fantastic experience: Seacoast Athletics isn’t just a “gym”. This place is different. This place is better. This place is special. SA is a game changer. Keep reading…. It starts with HC Justin Mahan who designs the programming. Unlike other CF gyms, Justin offers multiple tracks tailored to meet your personal goals. This is unique and it allows anyone to improve and get fit regardless of your starting point. The facility is spotless. The equipment is top notch. The community is supportive, motivated and inclusive. This is your place to grow and thrive. And this is our place. The coaches are amazing. Highly qualified and personable, Lisa, Ralphachino, Kayla, and Nick will guide you and support your journey. I’ve trained at a lot of gyms. I’ve coached. I love being part of the Seacoast Athletics family and I am better for it. Come and find out for yourself

Fantastic experience: Seacoast Athletics has been an amazing gym for me. I am so glad I made the decision to join 7 months ago. Since joining I have gotten strong and healthy again. The coaches at SA are the reason I always look forward to walking through the doors. They are true coaches. They teach and correct when needed but also push me to push myself. The gym itself has high end equipment, is always clean, and they are constantly reinvesting in the gym with new equipment. I always leave with a sense of accomplishment. They are the full package....knowledge, fun, and positive energy. I highly recommend Seacoast Athletics to anyone. Christine Joyce

Fantastic experience: After almost 6 months at Seacoast Athletics, I can confidently say that there is no better gym on the seacoast. I walked in on my first day fat and out of shape. Today I feel better than I ever have. The community at Seacoast Athletics is incredibly friendly. I was made to feel welcome by the coaches and other members from the minute I walked in the door. I now look forward to going to the gym, which is something I never thought I would say. The class schedule is the best I’ve ever seen, and I had looked at a lot of different gyms. No matter what shift you work, there is a class for you several days a week. All of the coaches are incredible. Their ability to help you progress in different movements without overwhelming you is unmatched. There is a healthy variety of workouts, and you know what they will be at the start of every week. There are different options to choose from, and the coaches always make sure you are comfortable with the movements. They also help scale them to your ability and are able to work around injuries with no issues. The gym is also spotless. Every piece of equipment is cleaned after every use and the floors are mopped after every class. To anyone reading this looking for a new gym, your search is over. Stop reading reviews, and come in for a class. You won’t regret it.

Fantastic experience: I trained with Justin for about a year. It was a very positive experience. Justin is very knowledgeable and is capable of putting the program together for any experience level. I highly recommend seacoast athletics.

Fantastic experience: I have had the privilege of knowing Justin for the past 4 years. Working with him has completely changed my life for the better. When I first met him I was a shy teenager who had never worked out before. Since working with him and getting involved with the Seacoast Athletics community it has allowed me to become more confident in myself and what I am able to accomplish. All of the coaches at SA genuinely care about your success and progress. All of the members are also so welcoming, so it really helps create the sense of community. Anyone looking for a gym give this a try and I am sure you will fall in love with it as I have.

Fantastic experience: I love this place! Motivating atmosphere, excellent programming and great coaches.Quality of movement is highly prioritized for safety and efficiency. The programming is exceptional. I cannot say enough good things about this place. Whether it's group classes or individual programming, gets to know you individually so they can help you be better than you were yesterday. Highly recommended place to join to be healthy physically and mentally.

Fantastic experience: I was finding that i was getting injured more frequently than I liked doing the things I love (skiing, surfing, and golf) so I was recommended seacoast athletics for strength and conditioning training. Justin has classes and programming that are geared towards keeping us active and healthy and i have felt great since training at SA. Recently i went on a ski trip and usually i am ridiculously sore after my first big day skiing. This year I woke up after day 1 and for the first time wasn't crazy sore. I attribute this to the type of training at SA as it is a good mix of appropriate level strength and conditioning. Highly recommend SA if you are looking for a place to stay healthy and strong to do the activities you love pain free.

Fantastic experience: I’ve been working out at Seacoast Athletics for more than a year and wouldn’t go anywhere else. There is a good mix of ages and abilities, a varied and entertaining plan for each class and knowledgeable coaches. I’m an older adult and feel fine working out alongside twenty year olds because Justin helps me scale the workout so that I don’t injure myself. He has extensive knowledge of human physiology and exercise techniques that enable him to guide each person towards their goals. I highly recommend Seacoast Athletics to anyone who wants to achieve practical and functional fitness.

Fantastic experience: Love this gym and the fantastic one on one training sessions with Justin!

Fantastic experience: Seacoast Athletics has completely changed my perspective on being a 46 year old. For the first time in years I’m feeling like an athlete again. When I started your classes I had to do step ups on the 18 inch box because I didn’t have the stamina to do box jumps. Last two open gyms I was able to do box jumps on the 24 inch box. Today I was floored that I could to do 5 double unders in a row and I really appreciated Justin’s enthusiasm when he saw it. When I got home after class I touched the rim on my basketball hoop for the first time in well over 5 years. Thank you so much for your expertise and patience. Justin, Lisa, and Nick have all been so helpful and supportive. I’m so appreciative for all you’ve done for me and I’m excited to see what gains I can make in the future.

Fantastic experience: I have worked out in many gyms and this one is by far the best fit for me. Over the last 10 years my fitness goals have changed many times and at SA, whatever my goal is for the day, week, month, year, I know Justin and all the staff there will support me. I have the flexibility to work out with a group of peers yet personalize the workout for my benefit without judgement.

Fantastic experience: I am 110% confident whatever your fitness goals might be: weight loss, strength, endurance, and/or conditioning, you will find success at Seacoast Athletics. I have been a personal training client with Justin for 3 years. Working and progressing with him has been truly transformative. He initially created a program and coached me on straightening and rehabbing my lousy back. His programming did just that from 2017 to 2018. I have been back pain-free ever since. Then from 2019 to 2020, we focused on getting a lot stronger. I had never done any serious strong training (Powerlifting). Before starting the strength program, Justin tested my baseline strength for a 1 rep max. My starting baseline numbers were: Bench Press 175, Back Squat 250, Deadlift 280, and a Strict Press - 140. After his coaching and programming, my results are as follows: Bench Press 325, Back Squat 425, Deadlift 500, and a Strict Press 200. Thank you for all your help, Justin & Seacoast Athletics!

Fantastic experience: I’ve been to a lot of places and can without a doubt say Seacoast Athletics, with Justin, is an amazing place to work out and the staff is super helpful, encouraging, and friendly. Great mix of functional fitness with traditional gym equipment. Lots of space for Olympic lifting too. There are classes offered in the morning, at noon and in the evening – good, varied range of different options. Their group classes are challenging and fun they focus on strength training more than group classes I’ve tried which I love. It’s great to be able to really get stronger and have proper form in a group setting, while still getting that cardio in. It’s an excellent workout every time and Justin is able to keep things fresh month after month.

Fantastic experience: There is no better training facility on the seacost than Seacoast Athletics. Since joining eight months ago, I've lost 8lbs while still managing to add 30lbs to my bench press, PR my front squat and clean and jerk, string together 3-5 strict pull-ups, and increase my overall aerobic capacity including running a mile in under 7:30. Justin is the most thoughtful, knowledgeable, and caring coach I've ever had the pleasure of working with. His programming is so uniquely intentional and designed to truly build on your progress from week to week, which is completely unmatched by other facilities. His method works. Period. The gym is clean, safe, and welcoming. The coaching staff (including Justin's wife Lisa) are equally as caring and intentional, and there to meet you where you're at without question. Drop in - you won't be disappointed!

Fantastic experience: Positive: Communication , Professionalism , Quality Seacoast Athletics provides excellent coaching, challenging but fun workout programming, top quality equipment, as well as a clean and friendly environment. Justin and Lisa have great attention to detail, all around. Highly recommend!

Fantastic experience: Justin is a phenomenal coach! Being someone who is very hesitant to step outside my comfort zone, Justin was very welcoming and made sure I was setup for success when joining! No matter what goals you have, Justin is supportive to all and everyone who works out here are friendly, welcoming and just happy to be a part of this Seacoast family! Would recommend this gym to anyone!

Fantastic experience: Positive: Communication , Professionalism , Quality Seacoast Athletics is an amazing training facility. No matter your goals, Justin and his team will be with you every step of the way. Everyone at Seacoast is welcoming and instantly makes you feel like you’re a part of the family (with the added bonus of some friendly competition of course). Come workout with us!!!

Fantastic experience: Seacoast athletics is the best gym around! It is way more than a gym it is a community and a family all made possible by our great leader Justin! I started there the first day he opened the doors and hands down one of the best decisions I have ever made. Justin has such a great energy and truly cares about every one of his members. He has helped me immensely in achieving my goals and always pushes and challenges me. I cannot thank him enough and each and every member. I enjoy the positivity and love motivating others; I think I enjoy cheering and seeing others achieving their goals as much if not more than my own. Big shout out to the other amazing coaches as well Lisa, Nick, and Ralph! I look forward to many many years with Seacoast Athletics! If you're looking for a gym stop by and check it out cause words won't do it justice!

Fantastic experience: After training at Seacoast Athletics for the past 6 weeks, I can confidently say that Justin and team do a great job tailoring individual fitness goals with top notch programming, solid equipment, and a comfortable environment. There are a lot of options on the Seacoast, but for me what sets SA apart is the unwavering focus on mobility and functional movements. There is always a solid chunk of time dedicated to a mobility and stretching circuit that is specifically connected to day's programming, which is not as common as it should be in most gyms. All that, plus a great group of people!

Fantastic experience: Seacoast Athletics is a very impressive gym that provides athletes of any experience or conditioning level the opportunity to pursue wide ranging physical and athletic goals. The owner of the gym (Justin) is extremely knowledgeable and positive. Justin takes time with each member of the gym to help them advance their movement patterns to optimize performance and avoid injury. The group dynamic of the workouts is always motivational. It is awesome to see people advancing athletically and I am always inspired when members of the gym redefine what is possible! I am extremely grateful to be part of the Seacoast Athletics Community and want to thank SA for doing what they do! I would highly recommend.

Fantastic experience: It's the positive energy for me. I have had the privilege of being coached by Justin since moving to the seacoast 7 years ago. And within that time I've been able to witness his growth not only as a human being but as a mentor and an innovative programmer. His positive energy and upbeat manner is contagious throughout the gym cultivating an open and supportive community. He truly shows up everyday and pushes you to be better for yourself. If you're in the seacoast area and are looking to try out a new gym, you don't want to sleep on this one.

Fantastic experience: Seacoast athletics is THE best fitness gym on the seacoast.... actually in all of New England. If you have not stopped in to check the place out, meet the owner Justin and his wife Lisa, or even meet some of the member you are surely missing out! Wether you are looking to prepared for a certain sports season, looking to build muscle and get super strong, or looking to just stay fit into your golden years seacoast athletics is the place for you! Justin is the most knowledgeable, kind, and caring coach I’ve ever experienced. He can accommodate any person of any skill level or experience level! I can’t imagine myself anywhere else. What are you waiting for! Get in there and check it out!

Fantastic experience: Justin (owner) is as smart and intentional with training his athletes as he is physically strong - and Justin is JACKED! Professional and understanding, Justin’s approach to training myself and others is to take stock of ability and goals, and design an achievable progression to get there. I’ve never felt like I was being pushed beyond my ability. Quite the opposite. Justin takes care to make sure I’m not over doing it and asks questions to ensure I’m ready to try something new. I’m a significantly better athlete today than I was 2 years ago (I’ve been training with Justin for 18 months). My energy is high, I feel strong, and my kids can’t keep up with me. Now Justin has started his own gym doing things exactly as he wants it. If you’re looking to have more success in your training, and have another perspective in a training partner; then get into Seacoast Athletics and start starting. You won’t regret it. BONUS: He opened up his gym during the apocalypse and has procedures in place to keep everyone safe and healthy. It’s impressively safe. Check it out!

Fantastic experience: I've had the privilege of being taught by, coached by and mentored by the owner Justin Mahan in the fitness industry for the last 9 years. He pours his heart and soul into each of his clients and is meticulous about the small details. Seacoast Athletics has all of the little details. From the decals, to the way the gym is set up, to the apps that he uses to deliver your workouts and assist with your membership, to every piece of programming...every last thing has been specifically chosen or placed with his clients in mind. Additionally, it is incredibly clean and the Covid-19 policies in place keep your mind at ease. Justin cares so much about each of his clients and members that not only do his programming tracks help you meet your fitness goals but he also has extensive knowledge with injury prevention and can provide any movement modification that is necessary.

Fantastic experience: Positive: Communication , Professionalism , Quality Justin runs an immaculate gym and is extremely knowledgeable in his craft. He makes it a point to make you feel welcomed every time you walk in the door and his enthusiasm is contagious. Working out is actually fun again at Seacoast Athletics!

Fantastic experience: As someone with a number of health conditions, fitness is simultaneously very important and very challenging for my overall well-being. Justin has invested in me to find ways for me to not only meet my goals, but go WAY beyond what I even thought was possible or that I was capable of. After trying countless different types of fitness activities (TRX, pilates, CrossFit, aerobic group classes, barre, all the cardio exercise machines, lap swimming, running...), none have fully worked for my body, let alone kept my interest or made me feel so proud and so often. Justin’s unique approach to strength and fitness has stood out to me from a motivation (it’s always interesting and the perfect amount of challenge, never overwhelming) and results perspective. I’ve hit more personal bests with no injuries (knock on wood!) since training with him full time now. This strength and sense of accomplishment has carried over not only into my other fitness-related pursuits, but also into my professional and personal lives where I’m happier and a better support for those I love and care about. Overall, I can’t recommend SA, and the fitness community Justin and his wife are building together enough. It is truly a labor of love. You will know it from the moment you step into the SA world. If you’re not sure, I encourage you to give it a shot. I certainly will never look back on the day I found the courage to give it a try. I would not be the person I am today if it weren’t for Justin and all he does for this community. I look forward to training for years ahead—both with him and because of him.
