The Effects Of Body Tension On Martial Arts Movement

As we work out way through class, what am I looking for in movement? 

What are some of the skills to identify, that if I can call attention to, the members in the group- myself included can remember and work on in our own training outside of class? 

Removing body tension. 

Working on moving as fluidly and relaxed as possible no matter the exercise, waza, or kata. 

Remaining relaxed helps keep correct body alignment and balance, allows one to adapt to changes in movement, and provides for ukemi. 

I'm always looking and impressing to remove tension in a person's martial arts movement. 

Junan taiso- body stretching is the first step, along with light exercise to keep the joints moving- walking is great for this. As we make our way through class, after we have been doing an exercise or waza for a bit, I stop the group and ask: what are you feeling right now? 

Pause for a moment and stand relaxed shizen. 

Any points on the body that feel stiff? 

Lower back? 



Where have you been carrying tension through what was just being practiced? 

Can we explore footwork and posture (kamae) to correct the tension? 

Perhaps more junan taiso and body work in that area? 

Constantly eliminating tension.

The aim of the Shinmyoken dojo (school of the life giving sword) is to understand nature and the movement of being zero through taijutsu. The school exists to create and transmit this through the experience of isshi soden.

Located in Westchester New York, the Shinmyoken dojo is a martial arts training group founded in 2005 with the aim of coming together as martial arts friends to study the Japanese martial arts of Masaaki Hatsumi through the lessons of the Bujinkan dojo. 

As friends (buyu) we come together to grow, learn, and share our individual potential in this wonderful martial art. In our group there is no beginner or advanced classes, as we all have the capacity to learn the martial arts in great stride. 

No previous martial arts experience is needed, new members, and out of town or traveling Bujinkan buyu are always welcome. 

The focus of the group is to make progress each week in learning the martial arts, developing skill, self-defense ability, and an understanding of how and why people move. 

Training is supervised by Fred Feddeck who has been studying the Bujinkan dojo martial arts since 1993. 

In 2003 he was honored to take the godan shinsha with the training group later forming as a vehicle to study what he has been taught and experienced in the Bujinkan dojo martial arts. 

Joe Maurantonio, dai-shihan, is and continues to be his teacher and mentor. 


Training in budo taijutsu through our dojo is offered in three class formats. 

The first is our weekly Saturday morning classes from 9-11 AM at a local park in Yonkers which is accessible by car, bus, and Metro North train. 

Second is our regular weekly zoom class as a way to build on the physical practice-paired movements explored in our Saturday classes. 

Third is our monthly discussion class exploring martial arts philosophy, history, tactics, and kuden. 


Membership in the dojo is open to those eighteen years of age or older and who can abide by the rules of the Bujinkan. 

Those interested in joining the dojo will be asked to fill out a brief questionnaire as an introduction and meet with the head instructor before an invitation to watch a class will be extended, general martial arts questions and other training inquiries are also welcome.
