American Grappling Fundamentals

Come join us in one of the most popular, fast growing combat sports in the world. Grappling is an ancient art birthed in the early centuries by soldiers, gladiators, and warriors that fought for their kingdoms and communities. We combine several styles of grappling for self defense conditioning and techniques to protect ourselves from whatever comes our way!


The Beginning

Wrestling that included grappling methods are referenced in the Christian Bible, The Iliad, and the Indian Vedas. Ancient Greek wrestling featured this technique in a sport called Pále that was highlighted during the Olympic Games. Wrestlers competed to earn points by touching one another’s shoulders, hips, and backs to the ground.


Grappling moved through Japan, France, and England during the middle ages. Over time, grappling took on qualities of freestyle wrestling, Judo, and Brazilian Jiu-jitsu. Classic Jiu-Jutsu developed between 1467 and 1573, as individuals used unarmed combat combined with weaponry.

Daggers, sickles, chains, and swords were favorites of classic Ju-Jutsu athletes who practiced armored grappling. These wrestlers relied on arm- and leglocks and choking to disarm their competitors. The latter is frowned upon today.


Some grappling champions use freestyle wrestling takedowns and rely on Sambo, and Catch-As-Catch-Can style moves to take down competitors. Many self-defense class teachers use traditional Jiu-Jutsu moves, including submission grappling to overpower people.

The sport does not involve striking, but values touching the hip, shoulder, and back to the ground and rewards these moves with points that can add up to win a match. Competitors can also tap out, ending a match because they want to forfeit from intense pain or to preserve their strength.

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!!

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!

- Paul Cronin

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!!!

Sean is very accommodating as well, I have a high demand work schedule that’s constantly changing, he is always bending to my needs. I would recommend Boom Athletics to anyone that needs to make a positive change in their life.
