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!

Have known and worked with Sean for decades; he knows his stuff; he translates meaning to his clientele very well. Top notch character and service.

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 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 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!!

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!

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!

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!

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!!!
