  • Are You Serious?

    What does it mean to be serious about your training? Does it mean you are always straight faced at the dojo? Does it mean you are very formal? Does it mean you are very regimented and organized? For me, it means something else. This past weekend I got to teach at a wonderful training camp […]

  • An-shu Rumiko

    At the beginning of this month we had the honor of hosting An-shu Rumiko Hayes for her first ever, solo seminar.

An-shu Rumiko covered many topics and ideas on […]

  • Set Side Foot Seminar

    Set Side Foot is a concept that allows you to maintain kamae throughout all your movement whether striking, throwing or applying locks. Kamae is not a position to start from and then do techniques, it must be maintained the entire time while doing taijutsu. This course shows you how to set yourself to be in […]

  • Cover Creates Control

    Our martial art is not a sport. It grew from a need to protect yourself in a life or death situation not from realitively safe competitions. Yet many people train without considering this. They defend and attack to satisfy their ego instead of to protect their life. Cover Creates Control is about how to first […]

  • In Gravity

    At this past Black Belt Training in Dayton I was asked to teach a short session. My goal was to show people how to get into fighting focus, what athletes call the zone. This is done with a particular breathing pattern, spinal alignment, hand alignments and…getting into gravity. The combination of these things help move […]

  • May I Take A Moment Of Your Time?

    Dear Friends of To-Shin Do, If I may, I would like to take a moment and speak to you about manners. Many people today believe manners are dying away. There is quite a bit of evidence to back this online and in the news. Just recently I was solicited by a number of people asking […]

  • Are You Breathing?

    When you are training, are you breathing? Seems like a silly question, you may think of course I am, but are you? If you tense up doing a kata or technique If you lose your focus during training If you start thinking about what you should do If you feel yourself rushing ahead to the […]

  • Clear Goals

    With the new year many people are making resolutions and setting goals for 2018. This thought reminded me of a conversation I overheard at festival this year right before the fire ceremony. Someone was asked if they were going to put a stick in the fire and their response was no because they had done […]

  • Women's Self-Defense Warning

    I’ve noticed an increase in Women’s Self Defense classes being offered recently. There is a need for them, however I wish to caution those of you offering them. There is a distinct difference between Women’s Self Defense, teaching structural and strategic ideas to a smaller person being attacked by a stranger, and dealing with intimate […]

As I watched people at Festival this year I got to see an extreme spectrum […]
