Boom! Athletics

Our Coaches

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!

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!
