What is Jiu Jitsu?

Jiu Jitsu is a grappling art that emphasizes the ability to control an opponent on the ground and defend against ground attacks. Jiu Jitsu utilizes principles of leverage and body positioning to allow people of all sizes and shapes to defend and apply advanced technique against any training partner. The great jiu jitsu players know that it’s not just a physical contest, but a contest of the mind. Like a game of chess, jiu jitsu offers those who enjoy an intellectual challenge the chance to think five moves ahead and develop a strategy that outsmarts their opponent. Whether you’re a life-long martial artist or brand new, jiu jitsu offers everyone an individual experience and the chance to develop skill and confidence in hand-to-hand ground combat.

"Jiu Jitsu is one of the very few things in my life that can quiet all of the noise in my head. Having such a tangible and physical challenge in front of you that needs to be solved is so foreign but so refreshing. It’s been a great outlet for relieving stress."


"I have been honored to be a part of the Monadnock bjj family for several years now. I put both of our daughters in the kid’s program for about 2 years before I got up the courage to join in. It was a pleasure to watch them grow and develop in their newfound grappling skills.Read More

That was the first time I got to watch either of them really exert themselves and push their limits physically. Then, after class one fateful evening, my 12 year old daughter was able to demonstrate a sweet take-down…on me. I joined the adult class that next week and haven’t looked back.It’s an intense and humbling experience to begin jiujitsu as an adult but it has been life changing in many wonderful ways. The people at Monadnock are great. Everyone is friendly, and willing to give and receive advice when needed. The sport seems to self-select for humility and that is reflected in our group. I have learned things there in the past few years that have made me a better father and husband. I have gained a much better sense of patience. It has been very helpful for me personally and I am proud to participate with those folks and call them my friends.”
