I don’t know why I waited so long! Everyone was so nice and welcoming. Coach Steve guided me through my first workout and helped choose weights appropriate for me. A few days later, I took my first kickboxing class in 9 years and absolutely loved it!
I feel silly for being intimidated before, now I’m excited to get into a routine with the classes!

At 30 years old I’m in the best shape of my life because of they hard work we all put in everyday. Ever single person in the gym pushes me or inspires me to be better and keep on improving. The one thing I really learned at boom is it doesn’t matter if you’re the best, the fastest, or the strongest, you’re only competing with yourself. If you can beat the person you were yesterday, physically, mentally, or emotionally, then you are making strides in the right direction.

I have never felt as comfortable and encouraged as I do here. The owners, coaches, and members are some of the greatest people I’ve ever met! If you haven’t tried out Sonic Boom yet, what are you waiting for????

I am so much stronger than I was when I started here. I was 52 when I started and thought I was already too old for this. I am now 60 years old and never dreamed I would be lifting what I am and feeling the way I do. The gym has helped immensely with my balance and handling my every day stress. I just feel I’m the healthiest I have ever been. Every member that I work out with treats me just like anyone else and don’t let me slack on anything. In fact they cheer me on and that is huge. It’s like an extended family. It makes it fun and makes me want to show up with my best every class.

Kickboxing
If you like to move you can feel the burn while jabbing, roundhouse kicking, and uppercutting the bags during our kickboxing classes. It's not all gloves though, our coaches mix in plenty of cardio and weight movements that will make sure your heart rate stays at a nice elevated pace. Sonic Boom also utilizes the Impact Wrap system to keep track of how many strikes your punching bag takes and displaying that across a live leaderboard during class.
Best of all: One Sonic Boom membership includes both Strength & Conditioning and Kickboxing classes, so you are free to explore both options!

MORE FROM OUR FAM
I was a multi-sport athlete most of my life. I did not need to be convinced to work out, it was second nature. That all changed when the pandemic hit and I found out I was also pregnant! All of a sudden I had a child and had lost some motivation to work out. I tried going to a gym alone like I had done in the past, but I needed more. My body had changed and so had my life. I wanted to find a place that could give me the best workout with the little bit of free time I had. I still craved a competitive environment but more than that, a place that I could find my love of working out and being apart of a team atmosphere again. A place I could push myself and become stronger not only physically, but mentally and emotionally as well. ENTER SONIC BOOM!!!
From the first day I walked in I was immediately welcomed not only by the incredible staff but also the amazing members. The workouts are different every single day and that helps keep me motivated. Workouts are tough but we cheer each other on like a team. This place simply makes all my bad days better. About a year and a half later I have transformed as a person and I am 100 times happier and healthier since joining the Sonic Boom Family-Thank you to everyone single member and the amazing coaches for your part in that - Steph
Whether you’ve been working out all of your life or brand new, the trainers here will work with you to make sure you’re doing everything safely and effectively. They’re also some of the nicest, most encouraging people I’ve ever met. I felt instantly comfortable with this gym when I started. In the six months that I’ve been a member, I’ve progressed so much physically and mentally. I am stronger, healthier, and happier. I recommend this gym to anyone who is looking for real change and progress in their life. -Dani
Fantastic gym, the guys there have changed my strength, endurance, and mental toughness. I’m glad that I chose to join. - Gabe
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!! - Diana
