Why Adults Walk In
Fitness You'll Actually Keep Doing.
The gym got boring by February
A skill with belts, forms and a next step
Too out of shape to start something new
Class scales to whatever shape you're in tonight
Never learned how to protect yourself
Practical self-defense drilled until it's automatic
Stress follows you home from work
An hour where nothing else exists but the mat
60+
We have students still training past
Designed For This Age
Depth you don't get from a franchise.
Giroux Bros was started by brothers Steve and Jeff Giroux, who have trained and taught since 1984. Steve opened the school in 1999, is an 8th Degree Black Belt, a three-time Grand Champion, a Wieland Norris Award winner, and sits on the UFAF Board of Directors. The Newtonville dojo is run today by Master Danny Sohmer, who started training here in 2002 and brought home two Norris Cups at the 2024 World Championships. Every year the team trains and competes with the wider Chuck Norris System.
Real Lineage

Self-Defense That Holds Up

A Full-Body Workout

Train With Your Kids

Calm Under Pressure
Learn to stay steady when everything around you is hectic.
No Ego On The Mat
Beginners are helped, not tested. Respect runs both directions.
One Hour On The Mat.

Basics
