Boom is awesome! Sean is a great trainer with a lot of knowledge. I have been going to the strength classes and the striking classes, both are great. The gym is very clean and equipment is top of the line. 10/10 highly recommended the Saturday class.

We’ve had our 11 year old son seeing Sean now for just about 4 months to help him move better in lacrosse and the improvement in his game is incredible. He has so much more confidence, energy and drive. Even other parents whose kids play lacrosse with him noticed a huge difference in how he moved. My son was so excited to tell Sean that he doesn’t get winded anymore by the end of the game and that he has so much energy!!! So much so that my 14 year old wanted to join. He’s been for just about a month and absolutely loves it. I can’t wait to see what the next few months bring for them and how much stronger they both will get. Sean invests his time and knowledge in teaching these kids hard work and perseverance and I know this will stay with them for years to come.
