There is definitely a big family vibe at Sonic Boom. The coaches are always available to help you out with any question you have, at any time of the day. If you're just trying to become fitter, lose stubborn weight, or improve your weightlifting Boom is by far the best option in the area. I've been going to Sonic Boom for about 6 months now and I can't believe how much time I wasted at big brand gyms doing ineffective work outs. Before joining Sonic Boom I was getting pretty upset about a weight gain that kept on creeping up no matter how hard I tried to stop it. It was making my clothes uncomfortably tight and putting me in a bad mood all day. Fast forward to today and I'm back to what I weighed years ago, except now I'm stronger and my range of motion has greatly improved. The coaches have helped me every step of the way with chiseling away at my flexibility and introducing me to new lifts in a safe and non-intimating fashion. The members also deserve a special shout out for being super supportive during workouts and encouraging everyone to do their best. Getting started with a trial was not only free but very low pressure and well worth it for anyone slightly interested in what this gym has to offer. read more

Hard to put into words how much this place means to me! The coaches and members are incredible! They put so much heart and soul into everything they do day in and day out. Each and every person who walks in their doors will get their undivided attention when it's needed. In the last year and a half I have made amazing strides inside and outside of the gym and have gained some amazing friends on top of that! Even with some bumps in the road and a few steps backwards the last few months they keep pushing me to continue to move forward! Anyone who knows me knows how passionate I am about working out now and I haven't had this passion in many many years! I can't speak more highly of this gym! I am Down over 50lbs and many pants sizes since joining and most of all a better wife, mom, daughter and friend outside of the gym! Thank you guys for everything you do and following your dreams! read more

I've been a member at Sonic Boom for almost two years now and I absolutely love this place! I have gone to other gyms for years prior, but this gym has proven to have a more friendly and helpful atmosphere. The people in the classes are always so nice and make you feel welcome and the coaching staff is the best part of what you pay for! I would have never attempted to back squat in the weight room at other gyms, but here, the coaches teach you how to lift safely and properly and take pride in making sure you keep good form and increase strength! I love going in and having my work out laid out for me! Not to mention, you are in a small group of others doing the same workout so there is motivation to finish and finish strong! I highly recommend this gym to anyone, young or older! read more

I started at sonic boom about a year ago. What I like most about this gym is they work with you. The classes are 60 minutes of cardio, strength training and lifting. I never really did weight training but the older I get I know that it is very important for my health. The instructors help you with all of the exercises and modify it to your level. They make sure you are doing the exercises correctly so you don't injure yourself. There are a lot of class times, personal training and open gym . The clientele are young and old. I would highly recommend this gym to all beginners and seasoned gym goers! I'm 60 years old and everyone there makes you feel welcome and are willing to work with you! If you want a great workout go to Boom! read more
